0949384RoweThis award provides funds for a hand-held AXS X-ray fluorescence unit. The unit will be used to obtain rapid chemostratigraphic information from organic-rich mudstones. The new instrument will primarily be used to prioritize samples for more detailed laboratory analysis. Samples will be screened in the field and from a core repository. The analytical goals are to match geochemical characteristics with sedimentology and stratigraphy - with emaphasis on the Permo-Triassic Boundary in the Panthalassic and Tethyan Oceans and the Barnett Shale. The PI intends to survey rock outcroppings in order to prioritize subsequent laboratory analyses. Of particular interest is determining mudstone chemostratigraphy. The instrument will support undergraduate and graduate students, the PI and internal/external collaborators. The PI routinely uses analytical instrumentation in geochemistry coursework. This acquisition will support research training for underrepresented groups. The instrument will be housed in the UT Arlington (UTA) Geoscience Building when not being used in the core repository or in the field. ***

0949384Rowe 该奖项为手持式 AXS X 射线荧光装置提供资金。该装置将用于从富含有机物的泥岩中快速获取化学地层信息。新仪器将主要用于对样品进行优先排序，以进行更详细的实验室分析。样品将在现场和核心存储库中进行筛选。分析目标是将地球化学特征与沉积学和地层学相匹配，重点是泛海洋和特提斯洋的二叠纪-三叠纪边界以及巴尼特页岩。 PI 打算调查岩石露头，以便确定后续实验室分析的优先顺序。特别令人感兴趣的是确定泥岩化学地层学。该工具将为本科生和研究生、PI 和内部/外部合作者提供支持。 PI 通常在地球化学课程中使用分析仪器。此次收购将支持针对代表性不足群体的研究培训。当该仪器不在核心储存库或现场使用时，将安置在 UT Arlington (UTA) 地球科学大楼内。 ***
