چکیده
ABSTRACT Archival charcoal tree-ring segments from the Mississippian center of Kincaid Mounds provide chronometric information for history this important site. However, recovered was originally treated with a paraffin consolidant, once common practice in American archaeology. This paper presents data on efficacy solvent pretreatment protocol and new wiggle-matched 14 C dates largest mound (Mound 10) at Kincaid. FTIR analysis known-age intentionally contaminated paraffin, as well archaeological material, show that chloroform is effective removing contamination. Wiggle-matched cutting final construction episodes Mound 10 Kincaid, indicate used late 1300s unique structure apex occurring around 1390. study demonstrates potential museum collections to contribute high-resolution chronological despite past conservation practices complicate dating.

Radiocarbon Dating: The Continuing Revolution
Radiocarbon (I4C) dating, now in its fifth decade of general use, continues to be the most widely employed method of inferring chronometric age for late Pleistocene and Holocene age materials recovered from archeological contexts. Over the last decade, several technical advances in I4C studies have provided contexts for a number of significant applications in archeology that were previously eit...
متن کاملRadiocarbon Dating of Ground Water
Radiocarbon dating of ground water is used in combination with the primary measurements of classical hydrological and chemical analyses. Radiocarbon dating will produce the best results when it involves multiple measurements or sequential sampling. The most useful data come from these comparisons and not from absolute ages. In the case of multiple measurements, the apparent ages of the ground w...
متن کاملRadiocarbon dating of charcoal and bone collagen associated with early pottery at Yuchanyan Cave, Hunan Province, China.
Yuchanyan Cave in Daoxian County, Hunan Province (People's Republic of China), yielded fragmentary remains of 2 or more ceramic vessels, in addition to large amounts of ash, a rich animal bone assemblage, cobble and flake artifacts, bone tools, and shell tools. The artifacts indicate that the cave was a Late Paleolithic foragers' camp. Here we report on the radiocarbon ages of the sediments bas...
