POLLEN AND STARCH ANALYSIS AT 35GR1507, OREGON

Nine pollen samples were examined from site 35GR1507 on the John Day River near
Dayville in Grant County, Oregon. These samples represent a column through a probable house
(Feature 3) that yielded a radiocarbon age of 4370 + 70 BP, a sample from Feature 2, a hearth,
and test samples outside the features. Pollen and starch analyses were undertaken to learn
about prehistoric vegetation at the time of occupation and use of plants by the occupants of this
site.

本研究对美国俄勒冈州格兰特县代维尔近郊约翰戴河沿岸的35GR1507遗址，开展了9份花粉样品的检测分析。本次采集的样品涵盖疑似房屋遗迹（Feature 3）的地层柱样，该遗迹的碳十四测年结果为4370±70 BP；同时包含遗迹2（Feature 2，一处灶址（hearth））的样品，以及遗迹外部的对照样品。本研究通过花粉与淀粉粒分析，旨在揭示该遗址被先民占据使用时期的史前植被状况，以及当时先民对植物资源的利用情况。
