Lithologic Discontinuities in Soils
Lithologic discontinuities are significant changes in particle size distribution or mineralogy that represent lithological differences within a soil column. Lithologic discontinuities in soils occur globally and are present when two or more different, vertically stacked, parent materials exist within a profile due to variations in past geologic or depositional processes. Recognition of these types of lithologic changes is important because pedoge…
Geoarchaeology and paleoecology of the deeply stratified Richard Beene site, Medina River valley, South-Central Texas, USA
Late Quaternary environments of the Waco Mammoth site, Texas USA
The Waco Mammoth Site (WMS) in central Texas contains the remains of the largest mammoth herd ( Mammuthus columbi ) in North America that died in a single catastrophic event. Most mammoths at the site died on a gravel bar of the ancient Bosque River adjacent to a collapsing tributary wall. However, the timing and cause of death of the 26 mammoths documented to date are controversial. The objectives of this research are to: describe and interpret …
Early Holocene soil cryoturbation in northeastern USA
Climatic and human controls on Holocene floodplain vegetation changes in eastern Pennsylvania based on the isotopic composition of soil organic matter
A paleoenvironmental time-series spanning the Holocene was constructed using 29 radiocarbon ages and 149 standardized δ 13 C som values from alluvial terrace profiles along the middle Delaware River valley. There is good agreement between increasing δ 13 C som and Panicoideae phytolith concentrations, suggesting that variations in C 4 biomass are a major contributor to changes in the soil δ 13 C. A measurement error deconvolution curve over time …
Late Quaternary alluvial history of the middle Owl Creek drainage basin in central Texas
Analysis of Site Formation History and Potential Disturbance of Stratigraphic Context in Vertisols at the Debra L. Friedkin Archaeological Site in Central Texas, USA
Archaeological sites within physically “active” soils, such as Vertisols, are considered suspect by archaeologists because of concern for possible disturbance of stratigraphic context. Pedology, micromorphology, and geochemistry are tools useful for assessing soil mixing. Clay‐rich floodplain soils (Typic Haplusterts) were examined at the Debra L. Friedkin archaeological site along Buttermilk Creek in southwestern Bell County, Texas, USA. The soi…

Assessing lithologic discontinuities and parent material uniformity within the Texas sandy mantle and implications for archaeological burial and preservation potential in upland settings
Alfisols within the Texas Gulf Coast Plain commonly exhibit textural contrasts between sandy, artifact-bearing A–E horizons (i.e., sandy mantle), and artifact-sterile clay-rich Bt (argillic) horizons. This has invoked debate about parent material uniformity and pedogenic versus geomorphic sandy mantle origins, which has implications for the scientific value of buried archaeological sites. To improve our understanding of archaeological burial in u…
The Buttermilk Creek Complex and the Origins of Clovis at the Debra L. Friedkin Site, Texas
A large artifact assemblage dating to 15,000 years ago lies beneath a Clovis assemblage in central Texas.
Late quaternary alluvial stratigraphy of a low-order tributary in central texas, USA and its response to climate and sediment supply
This paper presents the first comprehensive late Quaternary alluvial stratigraphic study of a low-order tributary in central Texas, using Cowhouse Creek as a case study. The late Pleistocene Jackson (JA) alluvium forms the elevated T2 terrace. The entrenched Holocene valley is filled with the buried Georgetown (GT) alluvium (approximately 11,000 to 8000 14 C yr B.P.) and associated Royalty paleosol, and the surficially exposed Fort Hood (FH) allu…
Late prehistoric soil fertility, irrigation management, and agricultural production in northwest coastal Peru
The Pampa de Chaparrí (Pampa) in hyperarid northwest coastal Peru is an ideal area to study late prehispanic agricultural technology and production because irrigation canals and furrowed fields have been preserved since abandonment approximately 500 years ago. We collected 55 samples for soil characterization, fertility, and micromorphic analyses and compared these results to a noncultivated control soil previously sampled in an adjacent valley. …
Royal Coachman (41CM111) An Early Middle Archaic Site along Cordova Creek in Comal County, Texas
The Royal Coachman site, 41CM111, is bisected by FM 306 near the highway’s eastern crossing of the Guadalupe River. Archeologists from the Texas Department of Transportation conducted extensive excavations at the site in 1980 and the Center for Archaeological Research carried out fieldwork related to geomorphic assessment of the deposits in 2002. The site contains at least three archeological components, an upper zone that may be of late Middle A…
C 4 Plant Productivity and Climate-CO 2 Variations in South-Central Texas during the Late Quaternary
A continuous record of organic carbon δ 13 C from a buried soil sequence in south-central Texas demonstrates: 1) strong coupling between marine and adjacent continental ecosystems in the late Pleistocene as a result of glacial meltwater entering the Gulf of Mexico and 2) ecosystem decoupling in the Holocene associated with a reduction of meltwater and a shift in global circulation patterns. In the late Pleistocene, reduction in C 4 plant producti…
Stable Carbon and Oxygen Isotopes in Soils
Archaeological Survey of Southwest Block and Selected Roads and Firebreaks at Camp Maxey, Lamar County, Texas
In June, July, and September 1998, The Center for Archaeological Research (CAR) of The University of Texas at San Antonio (UTSA) conducted an archaeological survey of approximately 1,000 acres for the Texas Army National Guard (TXARNG) on Camp Maxey, a TXARNG training facility in north-central Lamar County, Texas, under Sections 106 and 110 of the National Historic Preservation Act and the Antiquities Code of Texas. The TXARNG had identified the …

Archaeological Survey at Rancho de las Cabras, San Antonio Missions National Historic Park, 41WN30, Wilson County, Texas
A two-stage archaeological investigation and preliminary geomorphological assessment was conducted at Rancho de las Cabras, San Antonio Missions National Historical Park, by the Center for Archaeological Research (CAR) of The University of Texas at San Antonio for the National Park Service (NPS). The investigation was prompted by NPS plans to construct a parking lot and visitors' center near the Spanish colonial ruins (41WN30). The geomorphologic…
An Archaeological Survey of a Pipeline Right-of-way along Loop 1604 from IH-37 to the San Antonio River, Southeast Bexar County, Texas
In February 1997, the Center for Archaeological Research (CAR) of The University of Texas at San Antonio was contracted by the San Antonio Water Systems (SAWS) to conduct an intensive archaeological survey and geomorphological study along a proposed 5 .5-km water main right-of-way, from the junction of ill -3 7 and Loop 1604 to the San Antonio River in southeast Bexar County. Upon completion of a 1 DO-percent pedestrian survey, 10 backhoe trenche…
Late Quaternary Floodplain History of the Brazos River in East-Central Texas
The floodplain along a 75-km segment of the Brazos River, traversing the Gulf Coastal Plain of Texas, has a complex late Quaternary history. From 18,000 to 8500 yr B.P., the Brazos River was a competent meandering stream that migrated from one side of the floodplain to the other, creating a thick layer of coarse-grained lateral accretion deposits. After 8500 yr B.P., the hydrologic regime of the Brazos River changed. The river became an underfit …
Geoarchaeological investigations of henson creek
A complex late Quaternary alluvial history was documented along Henson Creek, a low order tributary on the Fort Hood Military Reservation in central Texas. Three Quaternary alluvial landforms were recognized: terrace 2 (T2), terrace 1 (T1), and the modern floodplain (T0). The late Pleistocene T2 terrace may contain an array of sites spanning the entire known cultural record, while T1 may have sites spanning the last 5000 years only. Five fluvial …
Late Quaternary Vegetation and Climate Changes in Central Texas Based on the Isotopic Composition of Organic Carbon
Stable carbon isotope analysis of organic carbon in alluvial deposits and soils of three streams in central Texas reveals significant shifts in the ratio of C 3 to C 4 plant biomass production during the past 15,000 yr. These temporal changes in vegetation appear to be in response to changes in climate. During the late Pleistocene, C 4 plants comprised only about 45 to 50% of the vegetative biomass in this area, suggesting that conditions were co…
