MACROFLORAL ANALYSIS AND AMS RADIOCARBON DATING OF SAMPLES FROM SITE LA 175774

Fill from two stain features at site LA 175774 were submitted for macrofloral analysis and AMS radiocarbon dating. These stain features contained thermally altered caliche, carbonstained soil, and charcoal fragments. Ceramics and features at the site suggest multiple occupation periods related to the Jornada Mogollon (circa 400-1350 AD) and possibly the Querecho/Maljamar phase. The expected age for the features is around AD 900-1300.采自LA 175774遗址两处染色遗存的填积物已被送检，用于开展大植物遗存分析与加速器质谱碳十四测年（AMS Radiocarbon Dating）。该类染色遗存包含经热改造的钙结壳、碳染土壤及炭屑碎片。该遗址出土的陶器与遗存迹象表明，其存在多段与约罗纳莫戈隆文化（Jornada Mogollon，约公元400-1350年）相关的居住阶段，亦可能归属奎雷乔/马尔哈马尔阶段（Querecho/Maljamar phase）。该类遗存的预期测年范围约为公元900-1300年。
