CHARCOAL IDENTIFICATION AND AMS RADIOCARBON DATING OF SAMPLES FROM SITES 42CB2316 AND 42EM15, UTAH, AND AMS RADIOCARBON DATING OF JUNIPER BARK FROM THE MIKKELSON SITE (ML 4764), UTAH

Four charcoal samples from sites 42Cb2316 and 42Em15 were submitted for identification and AMS radiocarbon dating. These sites are located in Range Creek Canyon, eastern Utah, and represent Fremont habitation sites. In addition, a portion of juniper bark from a mat with a whole black-on-white jar sitting on it from the Mikkelson Site (ML 4764) was submitted for AMS radiocarbon dating. The mat with the jar was partially buried beneath the surface in a small rockshelter with a Formative/Fremont/Anasazi association. A total of five AMS radiocarbon dates were obtained.

本次送检了采自42Cb2316与42Em15两处遗址的4份炭样，用于物种鉴定与加速器质谱放射性碳定年（AMS Radiocarbon Dating）。这两处遗址坐落于犹他州东部的里奇克里克峡谷（Range Creek Canyon），属于弗里蒙特人（Fremont）的定居遗址。此外，从米克尔森遗址（Mikkelson Site，编号ML 4764）一处铺有完整白地黑彩陶罐的草席上采集的杜松树皮样本，亦送检用于加速器质谱放射性碳定年。该草席与陶罐被部分掩埋于一处小型岩棚地表之下，该岩棚属于成型期（Formative）/弗里蒙特（Fremont）/阿纳萨齐（Anasazi）文化关联遗存。最终共获取5组加速器质谱放射性碳定年数据。
