Holocene and recent valley-bottom sediment storage decouples natural and anthropogenic hillslope erosion from sediment delivery to streams at time scales of 10 1 –10 4 yr in a third-order Yangtze Rive…
To assess the time scales and relative importance of temporal decoupling between hillslope erosion and the introduction of sediment to streams in a Yangtze River headwater basin, we used multiple techniques to date sediments in alluvial fans and terraces in a third-order stream valley draining a 30-km 2 catchment in SW Sichuan, China. Poorly sorted angular sediments in tributary-junction alluvial fans ranged in age from 11261 BCE to 1844 CE, and …
Luminescence Dating of Stone Structures in the Northeastern United States
There is no consensus on who built the numerous stone structures that dot the archaeological landscape in the northeastern United States. Professional archaeologists traditionally have attributed them to colonial farmers, but increasing numbers of archaeologists have joined many nonprofessional groups and Native Americans in arguing for Indigenous origins. Better understanding of these structures can be obtained by determining how old they are. T…
The signature of accumulated permanent uplift, northern Cascadia subduction zone
Uplift of the overriding plate at a subduction zone denotes interseismic strain accumulation, which is subsequently released during a megathrust earthquake. Although most interseismic strain is thought to be released elastically, observations of uplifted coastal regions at subduction zones worldwide indicate that some strain may result in permanent uplift. The Grays Harbor and Willapa Bay (Washington, USA) coastal region of the Cascadia subductio…
Implications of the loess record for Holocene climate and human settlement in Heye Catchment, Jiuzhaigou, eastern Tibetan Plateau, Sichuan, China
We examine the Holocene loess record in the Heye Catchment on the margins of the Tibetan Plateau (TP) and China Loess Plateau (CLP) to determine: the region to which the Heye Catchment climate is more similar; temporal change in wind strength; and modification of the loess record by mass wasting and human activity. Luminescence and radiocarbon dating demonstrate loess deposited in two periods: >11–8.6 ka and
The Contributions of Luminescence Dating of Sediments to Understanding the First Settlement of the Americas
Two major criteria for judging the validity of claims for early settlement of the Americas are solid dating by radiometric methods and evidence of stratigraphic integrity. Luminescence dating can provide information on both, not only producing a date but evaluating stratigraphic integrity by means of single-grain dating. Because of these qualities, luminescence has been applied to a large number of early sites. This paper reviews these applicatio…
Units in Ceramic Analysis and the Problem of Vessel Use Life
Shott (2022, American Antiquity 87:794-815) argues that making inferences from ceramic data requires first inferring use lives of vessels-something that is difficult to do. This comment argues that the problem of differential use life becomes more tractable if the assemblage, rather than the vessel, is the unit of analysis. Aside from empirical reasons, theoretical considerations also favor the assemblage as the appropriate unit
Dating stone arrangements using luminescence
Luminescence dating of rocks and sediments associated with various anthropogenic rock arrangements has the potential to provide age information for these hard-to-date features. This study applies infrared stimulated luminescence (IRSL) to sediments under rocks and to the rocks themselves from tipi rings and other features from the northern Plains. Dates are provided for 27 sediment and 5 rock samples from 7 archaeological sites in Montana, North …
Site occupation spans at Middle Ceramic Antelope Creek phase sites in the Southern Plains of Texas
Twenty-one AMS radiocarbon and optical stimulated luminescence assays from Early Ceramic (Plains Woodland) and Middle Ceramic (Antelope Creek) periods are reported from sites on the Cross Bar Ranch in Potter County, Texas including the first direct date on Phaseolus sp. remains in the Southern Plains. Calibrated radiocarbon dates and a single luminescence assay are used to evaluate site occupation spans during the Middle Ceramic Antelope Creek ph…
Re-evaluating Pleistocene-Holocene occupation of cave sites in north-west Thailand
Established chronologies indicate a long-term 'Hoabinhian' hunter-gatherer occupation of Mainland Southeast Asia during the Terminal Pleistocene to Mid-Holocene (45 000-3000 years ago). Here, the authors re-examine the 'Hoabinhian' sequence from north-west Thailand using new radiocarbon and luminescence data from Spirit Cave, Steep Cliff Cave and Banyan Valley Cave. The results indicate that hunter-gatherers exploited this ecologically diverse re…
Spatiotemporal variations and implications of luminescence sensitivity of quartz grains on the Chinese Loess Plateau since the last interglaciation
Although luminescence sensitivity of quartz grains of desert sands has been used in discriminating provenance, it still remains unclear about its spatiotemporal variations and climatic implications. In this paper, the luminescence sensitivity of quartz grains from the northern margin of the Chinese Loess Plateau (CLP) was studied using single-aliquot optically stimulated luminescence (OSL) and “pseudo” single-grain OSL measurements. Our results i…
The Rise and Fall of Alice Boer
In this paper we present a review of previous research carried out at the Alice Boer site coupled with new data regarding its lithic industry and ages. Our data suggest that the site, once believed to be at least 14,000 years old, most probably was occupied no earlier than 8000 years ago. The lithic material, comprising both bifacial and unifacial formal artifacts, can be associated to the Rioclarense industry. This industry is now well described…
Late Quaternary (≥MIS 3 to MIS 1) stratigraphic transitions in a highland Beringian landscape along the Kuskokwim River, Alaska
Stratigraphic records extending to Marine Oxygen Isotope Stage (MIS) 3 (57,000–29,000 cal yr BP) or older in Beringia are extremely rare. Three stratigraphic sections in interior western Alaska show near continuous sedimentological and environmental progressions extending from at least MIS 3, if not older, through MIS 1 (14,000 cal yr BP–present). The Kolmakof, Sue Creek, and VABM (vertical angle bench mark) Kuskokwim sections along the central K…

Revisiting Alice Boer
The Alice Boer site, located in Southeastern Brazil, was considered to be one of the oldest sites in the Americas, and a strong candidate for being a pre‐Clovis site. Ages obtained by researchers during the 1970s and 1980s put the site inside a chronological range between 2 and 14 ka, eventually reaching as old as 30 ka or even 130 ka. Between 2010 and 2012, our research team revisited the site to improve the knowledge of Paleoindian occupation i…
Optically stimulated luminescence dating of a probable Native American cairn and wall site in Eastern Pennsylvania
More than 5000 rock structure sites are found in northeastern United States, but their cultural attribution has long been debated. Some argue than many are prehistoric in origin, while others maintain they all date to colonial times. Few have been dated, and of those that have, the association of the dated material and the rocks can be challenged. Here, we provide luminescence analysis on the rocks themselves at a large site in eastern Pennsylvan…

Additional Dating at Williamson-Plainview and Type Milnesand Sites in Eastern New Mexico
Luminescence dates are provided for the Williamson-Plainview and Milnesand sites in the Southern High Plains, eastern New Mexico. These supplement radiocarbon dates reported earlier. The luminescence dates are consistent with the late Pleistocene radiocarbon dates
Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) Dating of Two Burned Clovis Wyandotte Chert Lithic Specimens from Paleo Crossing (33ME274), Ohio, USA
Paleo Crossing (33ME274), a Clovis site in Medina County, Northeast Ohio, USA, has played an important role in debates on the Pleistocene Peopling of the Americas given its published, and assumed accurate, age of 10,980 ± 75 BP (12,717–13,020 calibrated BP, median age 12,854 cal BP). However, there are still questions surrounding the radiocarbon ages from the site. We aimed to bypass using the association of charcoal with features or artifacts, a…
Luminescence Dating of Late Pleistocene and Holocene Sediments in Uruguay
The archaeological record in the Negro River in central Uruguay Republic is remarkable for its richness, including the presence of a significant number of Paleoindian fishtail points. As part of ongoing research on the earliest human occupations in this region, luminescence dating is applied to develop a terminal Pleistocene-Holocene regional chronology. Eight ages were derived from six samples taken from sedimentary fluvial deposits from two sit…
The “Lagoa do Camargo 1” Paleoindian site
Lagoa do Camargo 1, a Paleoindian archaeological site located in southeast Brazil dated between 10.5 and 8.3 ka, was studied using a variety of analyses: artifact and charcoal frequencies, soil morphology and micromorphology, magnetic analysis, optically stimulated luminescence, and radiocarbon dating. Our results show that the sandy tropical Oxisol present at the site was accumulated by episodic erosion and accumulation of materials along the sl…

The Rosa-Keystone Dunes Field
Stabilized sand sheets and dunes hold a remarkable amount of information on paleoenvironmental conditions under which late Quaternary landscapes evolved in northern subarctic regions. We provide the results of a project focused on understanding the development of lowland environments and ecosystems, including dunes and sand sheets, which were critical habitat for early human occupations in subarctic regions. Our study area is the Rosa-Keystone Du…
Early Holocene ritual complexity in South America
Dating Stone Alignments by Luminescence
Stone alignments, including tipi rings and drive lines, are abundant on the northern Plains and adjacent Rocky Mountains, but they have been notoriously difficult to date. This paper applies luminescence dating to sediments directly underneath the rocks to estimate the age of placement of the rock. This is based on the assumption that before the rock was emplaced, turbation processes brought sufficient grains to the surface, where sunlight reset …

Watson Brake, a Middle Archaic Mound Complex in Northeast Louisiana
Middle Archaic earthen mound complexes in the lower Mississippi valley are remote antecedents of the famous but much younger Poverty Point earthworks. Watson Brake is the largest and most complex of these early mound sites. Very extensive coring and stratigraphic studies, aided by 25 radiocarbon dates and six luminescence dates, show that minor earthworks were begun here at ca. 3500 B.C. in association with an oval arrangement of burned rock midd…
Effects of Temper on Strength of Ceramics
Results of strength tests on sand- and shell-tempered ceramics reported by Bronitsky and Hamer (1986) are difficult to interpret because of flawed experimental procedures and have questionable relevance to the archaeological record. Results from an improved procedure suggest shell-tempered ceramics as produced in prehistoric southeastern Missouri were stronger and tougher than sand-tempered counterparts

How old is Luzia? Luminescence dating and stratigraphic integrity at Lapa Vermelha, Lagoa Santa, Brazil
During an excavation in the 1970s, a disarticulated female human skeleton, later nicknamed Luzia, was discovered at 12m depth at Lapa Vermelha rockshelter in central Brazil. Radiocarbon dating of associated charcoal suggested an age of 11.4‐16.4 ka for the skeleton. The scattering of the skeletal parts, some uncertainty about the exact provenience of the skeleton, and evidence of pervasive insect turbation in the archaeological layers have raised…

User Guide for Luminescence Sampling in Archaeological and Geological Contexts
Luminescence dating provides a direct age estimate of the time of last exposure of quartz or feldspar minerals to light or heat and has been successfully applied to deposits, rock surfaces, and fired materials in a number of archaeological and geological settings. Sampling strategies are diverse and can be customized depending on local circumstances, although all sediment samples need to include a light-safe sample and material for dose-rate dete…
Post-Capsian Occupation in the Eastern Maghreb
The 1973–1976 excavations at Aïn Misteheyia, a Capsian site in eastern Algeria, revealed an archaeological sequence dated between 9500 and 6000 cal BP with evidence for technological and subsistence change coeval with what we now know to be the 8200 event. A human burial from the lowest levels at the site which are dated on land snail shell to at least 9000 cal BP, is dated twice on collagen, run 30 years apart by different laboratories using dif…

Problems of Ceramic Chronology in the Southeast
The chronology of shell-tempered pottery in the eastern United States is poorly understood, preventing any resolution to the question of how this pottery came to dominate ceramic assemblages in the late prehistoric period. Part of the problem lies in traditional dating methods that either provide only average dates that suppress variation or address depositional rather than manufacturing events. Better resolution can be obtained by dating individ…
Correspondence in Tree-Ring and Thermoluminescence Dating
Dating of early Navajo residence and special use sites, ca. A.D. 1500-1775, has been hampered by a lack of datable materials and poor precision in radiocarbon results. Methods described in this paper use materials ubiquitous at early Navajo sites in northwestern New Mexico and employ a dual strategy involving tree-ring dating of nonarchitectural wood and thermoluminescence assay of ceramics and burned rock. Comparison of samples obtained from a n…
Paleoindian Open‐Air Sites in Tropical Settings
Paleoindian sites in eastern South America are generally found inside rock‐shelters. Recently, we designed a program to find open‐air Paleoindian sites in the Lagoa Santa region of Brazil. Here, we present data gathered at Sumidouro site, a multicomponent site with a Paleoindian horizon, detected on a shoreline slope of Sumidouro Lake, Minas Gerais State. We present a model for late Pleistocene/Holocene slope evolution that suggests at least thre…
Accelerator Mass Spectrometry Radiocarbon Dating of Temper in Shell-Tempered Ceramics
Direct dating of artifacts is preferable to dating via association in most archaeological situations. In this article we describe and discuss the first application of accelerator mass spectrometry (AMS) to directly date temper particles in shell-tempered pottery. This method can be applied to ceramics from around the world that are tempered with freshwater or marine shell. To assess the method, we examine 34 new or previously reported dates (AMS …
Temporal Data Requirements, Luminescence Dates, and the Resolution of Chronological Structure of Late Prehistoric Deposits in the Central Mississippi River Valley
Our ability to order chronologically the archaeological record has long been linked to our capacity to generate explanations. Evolutionary explanations make even greater demands on chronological data requirements than most other approaches. Single date characterizations of deposits are wholly inadequate. Rather, we require distributions of dates that can be used to estimate duration and rates of assemblage formation. In addition, the events dated…

Thermoluminescence Dating of a Crucible Fragment From an Early Tin Processing Site in Turkey
Archaeological exploration in the Taurus mountains at Göltepe in south‐central Turkey has uncovered a site indicating the presence of extensive tin ore mining and smelling operations The most recent find of smelting crucible fragments allowed for a thermoluminescence‐hased age determination spanning a late fifth to early third millennium BC date. This result is consistent with a number of radiocarbon dates derived for charcoal also found at the s…
Paleoindian Cave Dwellers in the Amazon
A Paleoindian campsite has been uncovered in stratified prehistoric deposits in Caverna da Pedra Pintada at Monte Alegre in the Brazilian Amazon. Fifty-six radiocarbon dates on carbonized plant remains and 13 luminescence dates on lithics and sediment indicate a late Pleistocene age contemporary with North American Paleoindians. Paintings, triangular bifacial spear points, and other tools in the cave document a culture distinct from North America…
Luminescence dating and modern human origins
For the most recent evolutionary history of our species, that covering the emergence of anatomically modern humans during the last 100,000 years or more, few dating methods have such a wide range of potential application as luminescence dating. With its ability to provide direct ages in this time range for both archeological and depositional events, and using commonly occurring materials, luminescence seems to be an appropriate tool for almost an…

Luminescence dating of protohistoric pottery from the Great Basin
Luminescence analyses of several protohistoric brownware ceramics from the Great Basin have produced dates ranging from the 15th to 19th centuries. These begin to add detail to the chronology of these ceramics, which up until now has been poorly known despite their potential importance for understanding Numic population movement in the area. Use of the “slide method” for determining equivalent dose has circumvented problems due to nonlinearity in…
Firing Analysis of South‐eastern Missouri Indian Pottery Using Iron Mössbauer Spectroscopy
The Mössbauer spectra of prehistoric pottery and clay from the Malden Plain of south‐eastern Missouri, USA, were examined. The pottery dates from AD 500 to 1400. The earlier sherds were tempered with sand and the later ones with shell. The sherds and clay contain a mixture of illite, smectite, and kaolinite. Most samples of clay and sherds contained both ferric and ferrous species. The spectral parameters for the ferric species were %DLE Q ∼0. 7—…

Documents, Ceramics, Tree Rings, and Luminescence
Scholars have long debated the timing of final native abandonment of the Lower Rio Chama region of northern New Mexico. Traditional estimates of abandonment, based on ceramic styles, tree-ring dates, and documentary dates, range from A.D. 1550 to 1650. Although reasonably exact for many archaeological problems, this level of temporal resolution is insufficient in this case, given the rapid changes that occurred with Spanish colonization and settl…
Uranium‐series and Luminescence Dating of Volcanic Lithic Artefacts
U‐series dating was used to determine the growth rate of a feldspar‐to‐clay weathering rind in a mid‐Holocene Cascade–Olcott tradition andesite core, and luminescence dating (last exposure to sunlight) was used to date fine‐grained feldspars scraped from the surfaces of similar buried artefacts from a 14 C‐sediment‐dated archaeological site (45KI464) on the wet western slope of the Cascade Mountains of Washington. For U‐series dating, we measured…
Understanding Dating Applications
A recent critique (Espenshade, 2004) of an application of luminescence dating in New Mexico represents a misreading of the original work and a misunderstanding of how dates should be interpreted in archaeology. It is well known that the dating event (what is actually being dated) and the target event (what one wants to date) can differ. This difference accounts for the discrepancies noted in the New Mexico study and also makes problematic Espensh…
