EXPLORATORY POLLEN ANALYSIS AT 340T38 AND 340T72, OTTOWA COUNTY, OKLAHOMA

Six pollen samples from two sites in Ottowa County, Oklahoma, were examined
from buried soils and other strata. Three goals were established for pollen
analysis, including determining the extent of pollen preservation, describing the
general vegetation community for time periods represented, and searching for the presence of maize. Site 340T38 is represented by four samples, two of which were removed from a buried soil horizon that yielded a radiocarbon age of 1010 + 80 BP (C-13 adjusted) . Site 340T72 is represented by two samples, one of which was removed from an A horizon.

对取自美国俄克拉荷马州渥太华县（Ottowa County）两处遗址、产自埋藏土壤及其他地层的6份花粉样品开展了孢粉分析。本次分析设定了三项研究目标：其一为明确花粉的保存程度，其二为还原对应沉积时代的区域植被群落整体概况，其三为搜寻玉米（maize）的遗存痕迹。340T38遗址共有4份样品，其中2份采自某一埋藏土层位，该层位经碳13校正后的放射性碳测年结果为1010±80 BP。340T72遗址共有2份样品，其中1份采自A层（A horizon）。
