Sediment Core (Other Keyword)
1-6 (6 Records)
Twenty pollen samples collected from seven cores were examined to provide a stratigraphic record of vegetation. In addition, charcoal from three of the pollen samples were radiocarbon dated to provide date context for Cores 4, 15, and 16.
Pollen Analyses of Samples from New Jersey (2021)
A series of pollen samples representing five cores were submitted for pollen analysis. The pollen signatures from these cores are discussed below.
POLLEN ANALYSIS OF SAMPLES FROM THE CHEYENNE RIVER, SOUTH DAKOTA (2003)
Single pollen samples from ten cores from the Cheyenne River area in South Dakota were examined in search of evidence that might indicate that these sediments accumulated during the historic era. Pollen evidence for the historic era includes pollen from plants known to have been introduced into the western United States during the historic era and are not native to this area. Examples include common weeds such as Erodium cicutarium (cranesbill), Cirsium (Russian thistle), Trifolium...

POLLEN, STARCH, PHYTOLlTH, AND PROTEIN RESIDUE ANALYSIS OF ARTIFACTS AND SOIL SAMPLES FROM MIDDEN DEPOSITS AT SITES CA-ORA-263 AND CA-ORA-264; POLLEN, PHYTOLlTH, AND DIATOM ANALYSIS OF CORE SAMPLES FROM AN OFF-SITE LOCATION; AND ARCHAEOCLATIC MODELING FOR THE HELLMAN RANCH PROJECT, CALIFORNIA (2004)
Pollen, phytolith, starch, and protein residue analyses were conducted on artifacts recovered in association with burials at site CA-ORA-263 in southern California, as well as on the soil control samples associated with these artifacts collected from midden sediments. An isolated basin metate at site CA-ORA-264 and a soil control from the basin fill also were examined for pollen, starches, phytoliths, and possible protein residues. These analyses were undertaken to be able to more fully...
STRATIGRAPHIC POLLEN ANALYSIS OF ELEVEN CORES NEAR EDGEWOOD, MARYLAND (2003)
Several cores were extracted from sediments of the peninsula between the Bush and Gunpowder Rivers near Edgewood Maryland. Samples were extracted at irregular intervals from eleven of these cores and submitted for environmental pollen analysis in order to assist in determining ages for strata underlying the peninsula. Accurate determination of biostratigraphic ages are difficult, at best, and require extensive, close-interval sampling to determine changes in frequency and the appearance and...
