1-14 (14 Records)
Two ceramic sherds from pot busts at site 8PB6, the Boca Raton Inlet Midden 3 site, in southeast Florida were submitted for analysis of residue and radiocarbon dating. Analysis of the residue for pollen, starch, and phytoliths provides an opportunity to record visual, microscopic evidence of food processing. Examination of the residue with Fourier Transform infrared spectrometry (FTIR) to obtain an infra-red spectrum provides information on the presence of lipids and di- and tri-glycerides,...
INFRA-RED ANALYSIS OF SANDSTONE VESSEL FRAGMENTS, SITE 46KA142, WEST VIRGINIA (2007)
Site 46Ka142, the Burning Spring Branch site, is situated on a terrace above the Kanawha River in Kanawha County, West Virginia. This multi-component site contains remnants of a 19th-century domestic house and salt furnace within the plowzone. The upper portions of the unplowed remainder of the A-horizon contained a Late Prehistoric village and portions of a Late Woodland settlement. Six sandstone vessel fragments were recovered from a site component dating to a transition between the Late...

MACROFLORAL AND FTIR ANALYSIS OF ROASTING PIT FILL AT SITE 5RB709, NORTHWEST COLORADO (2007)
Fill from two roasting pits at site 5RB709 in northwest Colorado were examined for macrofloral remains. The fill from one of the roasting pits also was examined using Fourier Transform Infrared Spectrometry (FTIR). The site was tested as part of the Northwest Pipeline Corporation's proposed 2006 Vernal Recoat Project. The roasting pits are associated with Fremont occupation of the site, dating to AD 780-1030. Macrofloral analysis will be used to provide subsistence information concerning...
MACROFLORAL, PHYTOLITH, STARCH, AND ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM HERKIMER HOUSING AUTHORITY, SITE HHA-1 PRECONTACT, HERKIMER COUNTY, NEW YORK (2020)
Site HHA-1 represents precontact use of a level floodplain at the confluence of two major waterways, the Mohawk River and West Canada Creek. Three samples were collected from Feature 1, a circular fire-cracked rock (FCR) deposit, for macrofloral, phytolith, starch, and organic residue analysis, the latter using Fourier Transform Infrared Spectroscopy. These analyses examined sediments and FCR from the feature in search of evidence of economic activity.
Micromorphology of Hearth Features and FTIR Analysis of Clays at Xianrendong and Yuchanyan Cave: Reconstructing Pyrotechnology and Human Behaviour Connected with the Earliest Pottery (2017)
The cave sites of Xianrendong and Yuchanyan are known for having produced the earliest pottery sherds yet discovered, respectively 20,000 cal BP and 18,600 cal BP. Both of these Chinese Upper Palaeolithic sites have been systematically sampled for radiocarbon dating and geoarchaeological analysis. Through micromorphology we identified clay lined fire features and ash lenses at both caves, revealing technological behaviour concerning pyrotechnology and the manipulation of clays in the Chinese...
ORGANIC RESIDUE (FTIR) ANALYSIS OF HEARTH FILL FROM SITE 48SW16684, SWEETWATER COUNTY, WYOMING (2013)
Fill from a hearth at site 48SW16684 in southwestern Wyoming was submitted for organic residue analysis. The sample was tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). FTIR analysis provides information concerning the compounds that were extracted from the fill sample. Information concerning foods that might have been processed in association with the thermal feature at this site is derived from matches with our reference library of raw and processed plants and...
ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM SITE 48SW16682, SWEETWATER COUNTY, WYOMING (2013)
Fill from three hearths at site 48SW16682 in Sweetwater County,Wyoming were submitted for organic residue analysis using Fourier Transform Infrared Spectroscopy (FTIR). FTIR analysis provides information concerning the compounds that were extracted from the fill samples. Information concerning foods that might have been processed in association with thermal features at this site is derived from matches with our reference library of raw and processed plants and animals.
POLLEN ANALYSIS AT PREHISTORIC SITE 26CK7041 AND POLLEN, PHYTOLITH, MACROFLORAL, AND FOURIER TRANSFORM INFRARED SPECTROMETRY (FTIR) ANALYSES AT HISTORIC SITE 26CK7053 (2007)
Archaeobotanical samples were examined from two sites located on Oliver Ranch, approximately 10 miles southwest of Las Vegas, Nevada. Samples from two possible hearth or roasting features and a soil control were analyzed for pollen remains from prehistoric site 26CK7041. Samples also were submitted from three features at historic site 26CK7053. A sample believed to represent hearth/stove ash from Feature 1, a residential cabin, and four stratigraphic column samples from an area believed to...
POLLEN AND ORGANIC RESIDUE (FTIR) ANALYSIS FOR SITE 48SW883, SWEETWATER COUNTY, WYOMING (2007)
The Buck Draw site (48SW883) is located northeast of Wamsutter, Wyoming on the eastern flank of the Great Divide Basin. Three components were identified in the field and radiocarbon dated to 1400 ± 50 and 1820 ± 70 BP for Component I (the upper component), 5970 ± 50 BP for Component II (the middle component), and 5930 ± 40 BP and 5840 ± 40 BP for Component III (the lower component). Pollen was examined from sampled collected both inside and outside of features. In addition, FTIR (infra-red)...
POLLEN, PHYTOLITH, MACROFLORAL, AND ORGANIC RESIDUE (FTIR) ANALYSES, AND AMS RADIOCARBON DATING OF SAMPLES FROM THE CHARLES TOWNE LANDING STATE HISTORICAL SITE, (38CH1-PSTS), SOUTH CAROLINA (2007)
Ten samples from the historic Charles Towne Landing site (38CH1-PSTS) were analyzed for archaeobotanical remains. Samples from three possible planting features, a possible agricultural trench, a floor or processing area, and four possible postholes were examined for pollen, phytoliths, macrofloral remains, and/or using Fourier Transform infrared spectrometry (FTIR). The results of these analyses should provide information useful to interpreting the origin and function of these features...
