Technician Support: New Utah State University Luminescence Geochronology Laboratory

0744455 pederson这项资助为犹他州立大学（USU）新成立的发光地质年代学实验室的实验室技术人员提供为期五年的部分工资支持。USU发光地质年表实验室拥有一种新的光学激发发光（OSL）阅读器，能够进行单粒测量。该仪器是用慈善捐赠的资金购买的，该实验室现在完全可以用于测定矿物的“埋藏”年龄（或最后暴露在阳光下的日期），最常见的是石英砂。依赖于OSL技术的研究应用包括河流和海滩沉积物、滑坡和烧制陶器的定年，特别是在没有当代有机材料可用或埋葬年龄超过放射性碳定年最大值约50 Ka的地方。OSL是第四纪地貌学的独特测年工具，在美国存在的OSL实验室很少。该技术职位将推进实验室的目标，包括扩大OSL在地貌学、地质灾害和地质考古学研究中的应用，并支持学生的培训和研究

0744455PedersonThis grant provides partial salary support over a five year period for a laboratory technician in a recently established luminescence geochronology lab at Utah State University (USU). The USU luminescence geochronology lab houses a new optically stimulated luminescence (OSL) reader capable of single grain measurements. The instrument was acquired with funds from a charitable donation and the lab is now fully operational for dating the "burial" age (or date of last exposure to sunlight) of minerals, most commonly quartz sands. Research applications that rely on the OSL technique include dating of river and beach deposits, landslides and fired pottery, especially where no contemporary organic materials are available or where the burial ages exceed the radiocarbon dating maximum of ca. 50 Ka. OSL is unique dating tool for Quaternary geomorphology and few OSL labs exist in the U.S. This technical position will advance the goals of the lab which include expanding applications of OSL for studies in geomorphology, geohazards, and geoarchaeology, and to support student training and research.***
