POLLEN AND MACROFLORAL ANALYSIS FOR THE CARSON CITY FREEWAY PROJECT PHASE II, NEVADA

Twenty-two pollen and twenty macrofloral samples were collected from fill of structures and pits in the Carson City Freeway Phase 2 project. Fifty features were identified during Phase II testing. Analysis of pollen and macrofloral samples was prioritized to examine primarily structures. Eight radiocarbon dates have been received that indicate occupation between approximately 380 and 1760 BP. This phase of the analysis is considered to be an examination of the pollen and macrofloral records for preservation and recovery of data that can provide information on the past environment during this approximately 1400 years of occupation in the area, as well as provide evidence of some of the plants that people selected to exploit.从卡森城高速公路（Carson City Freeway）二期工程的建筑遗迹与坑洼充填堆积物中，共采集22份花粉样品与20份大植物遗存（macrofloral）样品。二期测试期间共识别出50处遗迹特征。本次研究优先开展花粉与大植物遗存样品分析，以重点考察相关建筑遗迹。目前已获取8组碳十四测年数据（radiocarbon dates），结果表明该区域的人类活动时段介于距今（Before Present，BP）约380年至1760年之间。本阶段分析的核心目标为核查花粉与大植物遗存记录，以评估样品保存状态并获取相关数据：这些数据既可揭示该区域近1400年人类活动时期的古环境信息，也可佐证当时人类选取利用的部分植物类群。
