ABSTRACT P.I.Glenn Goodfriend SBR-9312787 A number of new dating techniques for use in archaeology are currently in the development stages. Of these, aspartic acid racemization on shell of various sorts (particluarly ostrich egg shell) is the most exciting and reliable, covering new ranges of dates that other techniques are inadequate for. The current small project will be the first application of this technique to especially recent excavations from Lake Titicaca around the time of colonization. It will allow for a more detailed understanding of the dynamics surrounding a number of events, including environmental alteration/degradation, that happened around that time. It will also allow refinement of the dating techniques themselves. *** P\anthro\jfried\9312787.abs PIF Cp ) ! LIST PIF U . ! PHON_WINPIF r 9 ! HP PIF F ( ! _DEFAULTPIF ıx + ! ETAS_WINPIF 8 ! !

摘要 P.I.Glenn Goodfriend SBR-9312787 许多用于考古学的新测年技术目前正处于开发阶段。 其中，各种蛋壳（特别是鸵鸟蛋壳）上的天冬氨酸外消旋反应是最令人兴奋和可靠的，涵盖了其他技术无法满足的新日期范围。 当前的小型项目将首次将该技术应用于殖民时期的的喀喀湖的近期挖掘工作。 它将允许更详细地了解围绕当时发生的许多事件的动态，包括环境改变/退化。 它还将允许改进约会技术本身。 *** P\anthro\jfried\9312787.abs PIF Cp ) ! 列出 PIF U 。 ！ PHON_WINPIF r 9 ！ HP PIF F ( ! _DEFAULTPIF ıx + !
