This trip focuses on late Quaternary alluvial stratigraphy and geoarcheology in the central Great Plains of Kansas and extreme northern Oklahoma. The first stop is at the Claussen archeological site on the bank of Mill Creek in northeastern Kansas. An extensive cutbank at the Claussen site provides an opportunity to examine the stratigraphic relationships of early, middle, and late Holocene alluvial fills. Archeological materials are contained in these fills, including Paleoarchaic cultural deposits at depths of m below the land surface. We will cross a steep bioclimatic gradient as we travel west from tallgrass prairie at the Claussen site to the shortgrass prairie of southwestern Kansas. Stratified cultural deposits at Simshauser, including an early Paleoindian component, are contained in an alluvial fan on the margin of the draw. We will examine the soil-stratigraphy of the fan and hear about the results of recent archeological testing at the site. We will also examine thick sections of late Wisconsinan and early Holocene valley fill beneath a broad terrace in Mattox Draw.

PubMed Central. Toffolo, Michael B. The relative chronology of the Aegean Iron Age is robust. It is based on minute stylistic changes in the Submycenaean, Protogeometric and Geometric styles and their sub-phases. The small number of radiocarbon dates available for this time span is not sufficient to establish an absolute chronological sequence.

Here we present a new set of short-lived radiocarbon dates from the sites of Lefkandi, Kalapodi and Corinth in Greece. We focus on the crucial transition from the Submycenaean to the Protogeometric periods.

In recent decades, much tsunami and earthquake research has been focused on the coast of the Pacific Northwest, where more and more evidence points to large earthquakes and tsunamis in the past and the potential for more in the future. The source of these earthquakes and tsunamis is the Cascadia subduction zone, which lies mostly off shore and extends approximately miles 1, kilometers from Cape Mendocino in Northern California to Northern Vancouver Island, Canada. The Cascadia subduction zone is where the Juan de Fuca, Explorer, and Gorda tectonic plates are subducting under the North American plate.

It is now thought to be capable of producing great earthquakes of magnitude 8 or 9, like those off Indonesia in and Japan in

Plasma oxidation was used to obtain radiocarbon dates on six different materials from a naturally mummified baby bundle from the Lower Pecos River region of southwest Texas. This bundle was selected because it was thought to represent a single event and would illustrate the accuracy and precision of the plasma oxidation method. Plasma oxidation is shown to be a virtually non-destructive alternative to combustion.

Because only sub-milligram amounts of material are removed from an artifact over its exposed surface, no visible change in fragile materials has been observed, even under magnification. The method is best applied when natural organic contamination is unlikely and serious consideration of this issue is needed in all cases.

If organic contamination is present, it will have to be removed before plasma oxidation to obtain accurate radiocarbon dates. Radiocarbon dating. The application of the radiocarbon dating in archaeology has not served only to solve problems related with the establishment of chronologies, but also in the development of archaeological methods of excavation and interpretation. This has been possible because the dating method by radiocarbon provides a common temporary scale that transcends the cultural and regional frontiers.

It is even spoken of the revolution that has meant the fact that the application of this method has allowed to the archaeologist to pass from the construction of chronologies until the evaluation and dynamic interpretation of the archaeological data to build theories. This work explains and compares methods for the detection of 14 C, as the gas counting, the liquid scintillation counting and the mass spectrometry with accelerators.
