MACROFLORAL ANALYSIS AND AMS RADIOCARBON DATING OF SAMPLES FROM SITES CA-LAN-1359 AND CA-LAN-3018 IN THE LOS ANGELES NATIONAL FOREST, SOUTHERN CALIFORNIA

Samples from stratigraphic columns associated with earth ovens at sites CA-LAN-1359
and CAL-LAN-3018 in southern California were examined for macrofloral remains. Charcoal
and botanic samples also were submitted for identification, and charcoal in three samples from
CA-LAN-3018 were AMS radiocarbon dated. These sites are located along Upper Big Tujunga
Creek in the Angeles National Forest, Las Angeles County. They represent multi-functional
sites used for procurement and processing of lithic materials and food resources. Macrofloral
analysis will be used to provide subsistence information concerning plant resources utilized by
the various occupants of these sites.

针对加利福尼亚南部CA-LAN-1359与CAL-LAN-3018遗址内与土灶遗迹相关的地层柱样本，开展了大植物遗存检测分析。研究同时提交炭质样品与植物遗存样本进行种类鉴定，并对CAL-LAN-3018遗址的3份炭样实施了加速器质谱（AMS）碳十四测年。上述遗址坐落于洛杉矶县安吉莱斯国家森林内的大图琼加溪上游沿岸，均为兼具石器原料获取、加工以及食物资源开发利用功能的多用途考古遗址。本次大植物遗存分析将用于获取该遗址各时期居住者所利用的植物资源相关的生计模式信息。
