AMS Radiocarbon Analysis (Other Keyword)
276-283 (283 Records)
Three samples from cores in a marshy area adjacent to Tolay Creek, California, were submitted for radiocarbon dating. Botanic components of the peat and marsh deposits were separated, then submitted for AMS dating. Three radiocarbon dates were obtained.
RADIOCARBON DATES FOR SITES 23LE174 & 23CK302, MISSOURI (2007)
One botanic sample and four sediment samples from site 23CK302 were submitted for AMS radiocarbon dating. A single botanic sample from 23LE174 also was submitted for dating. Although the original intent was to recover microscopic charcoal from all four sediment samples, visual examination of the screened portion of two of the samples revealed the presence of small pieces of coal. Coal cannot be removed from the microscopic charcoal fraction and would have caused the determination of the...
RADIOCARBON DATES ON SAMPLES FROM THE CARBON AND CLAY CORES OF A BUDDHA STATUE AND ASSOCIATED NAGA THRONE, SRI VIJAYA PERIOD STATUARY (2009)
A large, bronze Thai sculpture of a Buddha and Naga, thought to be from the Sri Vijaya Empire in southern Thailand contained carbon and clay cores, which yielded sufficient carbon for radiocarbon dating. This statuary, cast in two pieces, is reputed to be from the Sri Vijaya Empire in the late 12th to mid 13th century. Radiocarbon dating of samples from both portions of this statuary was completed to verify the dates.
SHELL AMS RADIOCARBON DATE, CA-SDI-5017, YWCA GARNET PROJECT PACIFIC BEACH, SAN DIEGO COUNTY, CALIFORNIA (2007)
Several Argopecten ventricosus shells from Test Unit 7 (Table 1) from the west-central portion of the ethnographic Kumeyaay village of La Rinconada de Jamo (CA-SDI-5017), were submitted to be dated using the AMS radiocarbon dating method
STARCH, ORGANIC RESIDUE (FTIR) ANALYSIS, AND AMS RADIOCARBON DATING OF A CERAMIC SHERD FROM CANYON FERRY LAKE, LEWIS AND CLARK COUNTY, MONTANA (2010)
A ceramic vessel rim sherd recovered from Canyon Ferry Lake in Lewis and Clark County, Montana was submitted for starch, organic residue analysis, and AMS radiocarbon dating. The ceramic was tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR).
STARCH, PROTEIN RESIDUE, ORGANIC RESIDUE (FTIR), MACROFLORAL ANALYSIS, CHARCOAL IDENTIFICATION, AND AMS RADIOCARBON DATING OF SAMPLES FROM SITES 42JB1732, 42JB1739, 42JB1749, 42JB1760, 42JB1764, KEG MOUNTAIN RANCH, AND 42TO3974, UTAH (2011)
Lithic tools, groundstone, fire-cracked rock, charcoal, and sediment samples from sites 42JB1732, 42JB1739, 42JB1749, 42JB1760, 42JB1764, and Keg Mountain Ranch, in the Old River Bed Valley, western Utah, were submitted for starch, protein residue, organic residue, and macrofloral analyses, as well as charcoal identification and AMS radiocarbon dating. The samples were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). A basalt chopper from Clovis site 42TO3794,...
WOOD AND CHARCOAL IDENTIFICATION AND AMS RADIOCARBON DATING OF SAMPLES FROM B. F. SISK DAM, CALIFORNIA (2009)
Two wood samples and eight charcoal samples were submitted for identification and AMS radiocarbon dating. These samples were collected from Bench 5 and Bench 4 at the B. F. Sisk Dam in central California. Samples were identified, and radiocarbon dates were obtained on nine samples.
XAD PURIFICATION AND RADIOCARBON DATING OF BONE FROM CUNCAICHA ROCKSHELTER, PERUXAD PURIFICATION AND RADIOCARBON DATING OF BONE FROM CUNCAICHA ROCKSHELTER, PERU (2012)
Three samples of bone collected from Cuncaicha Rockshelter in Peru were pulverized at the University of Arizona and received for XAD purification and AMS radiocarbon dating. These samples represent three unique specimens identified as vicuña (Vicuna mensalis) or Andean deer (Hippocamelus antisensis).
