POLLEN, PHYTOLITH, AND MACROFLORAL ANALYSIS OF SAMPLES FROM FEATURE 57 AT THE SCU-LEAVY SITE, SANTA CLARA, CALIFORNIA

A Native American housepit (Feature 57) associated with Mission Santa Clara was discovered during excavations at the Leavy School of Business on the Santa Clara University in southern California. Feature 57 is the first Native American house to be identified archaeologically at Mission Santa Clara. Pollen, phytolith, and macrofloral analyses were conducted on a single soil sample collected from the housepit floor (Context 168). A floated light fraction sample also from Context 168 was examined for macrofloral remains. Two charcoal samples from post-abandonment fill (Context 133) were identified. Botanic analyses were undertaken to identify plants that were used, stored, and/or processed by the housepit occupants.科研人员在南加州圣克拉拉大学校园内的利维商学院（Leavy School of Business）开展考古发掘时，发现了一处与圣克拉拉传教团（Mission Santa Clara）相关的北美原住民房址坑（housepit，发掘特征57，Feature 57）。该发掘特征57（Feature 57）是圣克拉拉传教团范围内首个经考古学手段确认的北美原住民房址。研究人员对从该房址坑居住面采集的单份土壤样品（发掘单元168，Context 168）开展了孢粉（pollen）、植硅体（phytolith）与大植物遗存（macrofloral）分析。同时对同样采自发掘单元168（Context 168）的浮选轻组分样品（floated light fraction sample）开展了大植物遗存鉴定。从废弃后堆积层（post-abandonment fill，发掘单元133，Context 133）中提取的两份炭样已完成鉴定。本次植物考古分析（Botanic analyses）旨在鉴定该房址坑居住者曾使用、储存及/或加工的植物种类。
