Late Pleistocene site formation and paleoclimate at Lapa do Picareiro, Portugal
The cave site of Lapa do Picareiro, Portugal contains a deep (~10 m) sedimentary sequence representing much of the Middle and Upper Paleolithic, with abundant animal bones, lithic/bone/shell artifacts, and charcoal/ash in hearths. A deposition model based on 49 radiocarbon ages demonstrates average sedimentation rates of 0.1–0.3 mm a −1 between 9 and 45 ka. Extrapolation suggests an age at the base of the excavation of 65–78 ka. The cave sediment…

Geophysical Evaluation of the Richland and Holloway Mounds, Southeastern Louisiana, USA
The Mississippi River Valley contains some of the earliest records of Native American earthwork construction, extending back ∼6000 years. Louisiana contains over 700 mounds of cultural significance, most of which have not been examined, leaving significant gaps in our understanding of mound usage in this region. Using geophysical techniques, including magnetic susceptibility (MS) and electrical resistivity, the Richland (16WF183) and Holloway (16…

Magnetic susceptibility applied as an age–depth–climate relative dating technique using sediments from Scladina Cave, a Late Pleistocene cave site in Belgium
The magnetic susceptibility of cherts
Recent exploratory studies have suggested the potential of magnetic susceptibility (MS) as a rapid and low‐cost sourcing technique for lithic archaeological materials. Most commercially available susceptibility instruments, however, do not have the sensitivity to characterize weakly susceptible cherts and silicified woods. Comparative results from nine chert, two silicified wood, a porcellanite, and four obsidian sources using a highly sensitive,…
Detecting Palaeolithic Activity Areas Through Electrical Resistivity Survey
Paleoclimate and intersite correlations from Late Pleistocene/Holocene cave sites
During the last 10 years or so, magnetic susceptibility (MS) measurements of cave sediments from archaeological sites have been used for intrasite correlation and paleoclimate estimation. This is possible, if the context is appropriate, because the MS of these sediments result from climate processes active outside caves causing variations in magnetic properties of the sediments ultimately accumulating inside of caves. Once deposited, these materi…

A Test of the MSEC Method for Paleoclimate and intersite correlations from Late Pleistocene/Holocene cave sites in southern Europe
En los ultlmos diez alios, se han utilizado las mediciones de la susceptibilidad magnetica (MS) de los sedimentos de los yacimientos arqueologicos en cueva para establecer correlaciones entre yacimientos y una estimacion del paleoclima. Ello es posible porque la MS correspondiente a estos sedimentos es el resultado de los procesos activos del clima en el exterior de las cavidades y las variaciones en las propiedades magneticas de los sedimentos, …
Identification of the last glacial maximum in the Upper Paleolithic of Portugal using magnetic susceptibility measurements of Caldeirão Cave sediments
We have sampled Upper and Middle Paleolithic sediments in Caldeirão Cave, Portugal, for paleoclimatic analysis. This work involved measuring magnetic susceptibility (MS) on continuous vertical profiles of a series of ∼8 cc sediment samples, and using the MS data as a paleoclimate proxy. Previous work has shown that caves can be ideal recorders of paleoclimatic variations because they are protected environments. Pedogenesis outside the cave during…

High-Resolution Paleoclimatic Trends for the Holocene Identified Using Magnetic Susceptibility Data from Archaeological Excavations in Caves
Paleoclimate Characterization and Intra-site Correlation Using Magnetic Susceptibility Measurements
Magnetic susceptibility was measured for 630 samples from Holocene sediments taken from Konispol Cave, sw Albania. Comparisons between magnetic susceptibility profiles from three trenches within the cave show distinctive variations in magnetic susceptibility magnitudes and patterns that, in turn, allow direct correlations between trenches and estimates of small-scale sedimentation rate changes. Using 14C dates in conjunction with magnetic suscept…
Magnetic and Geochemical Variations as Indicators of Palaeoclimate and Archaeological Site Evolution
Le gisement acheuléen de Cagny-l'Épinette (Somme)
steppic landscape interrupted by trees. The climatic conditions were close to those of an interglacial, from the Tardiglacial to the Early Glacial. The lithic industries are characterized by bifaces with various morphologies. The flaking and blank production indicate an opportunistic behaviour which did not develop any sophisticated operating scheme. On the whole non-standardized flake tools were badly manufactured : they mainly consist of notche…

Radiocarbon and archaeomagnetic dates from Konispol Cave, Albania
Albania, isolated from Europe for nearly half a century, was closed to absolute archaeological dating during that time. New dates from an unusual large cave-site in southern Albania go beyond the single first radiocarbon date published for the country in ANTIQUITY in 1991, and permit the establishment of a radiocarbon and archaeomagnetic sequence
Unusual electrical resistivity effects associated with fast‐growing trees
A series of electrical resistivity profiles have been acquired in eucalyptus groves during archaeological surveys performed in Portugal. The combination of the sandy soils in the region plus the presence of high growth eucalyptus trees yielded anomalous resistivity values which were extremely high and showed large variability. Other moderate and low growth trees did not show similar unusual resistivities. We conclude that extreme caution must be …
Electrical resistivity surveys as indicators of site potential
Electrical resistivity surveys have been conducted, in conjunction with follow‐up auger and test excavations, to optimize the excavation potential within two European closed sites. The first site, Pont d'Ambon II rock shelter, is situated on the Dronne River in the Department of the Dordogne, southwestern France. It is located ∼100 m south of Pont d'Ambon I rock shelter, from which late Upper Paleolithic cultural material has been recovered. Auge…
Geoelectric stratigraphy and subsurface evaluation of quaternary stream sediments at the Cooper Basin, NE Texas
An electrical resistivity survey of a portion of the Cooper Reservoir Basin in northeast Texas has been used to delineate the major lithostratigraphic units of Quaternary flood plain deposits and subsurface paleogeomorphic features of interest to geoarchaeologists. This investigation was conducted to evaluate the fluviatile deposits along the South Sulphur River which flows through Cooper Basin, to identify the basin morphology, and to detect bur…

The rockwall in rockwall, texas
The city council of Rockwall, Texas, decided in 1985 to build a park containing an exposure of the “famed” rockwall after which the city and county of Rockwall derive their names. This wall, thought to be man‐made because of it's unusual brick‐like appearance, was first discovered in 1851. As a result of weathering, the wall has no surface exposure and crews working for the city had not been able to find it. Geological studies, published between …
