This MRI award funds a laser ablation (LA) system to couple with an existing Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The LA-ICP-MS allows elemental analysis of very small areas (micron scale) of solid geological or biological samples. The LA will enable the research programs of Union faculty and students, as well as those of researchers from outside institutions. The acquisition of the LA will greatly expand our ability to address both basic and applied questions in paleoclimatology, paleoenvironments, and high-temperature geochemistry (including volcanology and geochronology), and their connection to related geological, geochemical, atmospheric, hydrologic, and ecological systems. The LA will allow for both rapid throughput and high spatial resolution that is required by the proposed research activities. This instrumentation will allow the lab to expand its capabilities in geochemistry, and is critical to advancing the research needs of several Geosciences faculty and their students. The LA will advance research on developing multiproxy paleoclimate, palaeoceanographic, and paleoenvironmental records, specifically to: a) utilize stalagmites to develop climate records in temperate and tropical regions; b) investigate historical pollution events using stalagmites and bivalve shells; and c) develop and investigate elemental proxies in biological carbonates including bivalve shells and corals. The LA system will also advance high-temperature geochemical research, with projects on magma mixing, volatile content of magmas prior to eruption, and thermometry in volcanic rocks and deeply eroded mountain belts. The LA will be used in undergraduate independent research, the lab components of undergraduate courses, and will advance the research of two female pre-tenure faculty at nearby institutions as well as foster new collaborations at other institutions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该MRI奖为激光消融（LA）系统提供了与现有的电感耦合等离子体质谱仪（ICP-MS）相对的。 LA-ICP-MS允许对固体地质或生物样品的非常小的区域（微米尺度）进行元素分析。洛杉矶将使工会教师和学生以及外部机构的研究人员的研究计划。洛杉矶的获取将大大扩展我们在古气候，古环境和高温地球化学（包括火山学和地球人工学）中解决基本和应用问题的能力，以及它们与相关地质，地球，大气，水文学和生态系统的联系。洛杉矶将允许拟议的研究活动所要求的快速吞吐量和高空间分辨率。该仪器将使实验室能够扩展其在地球化学方面的能力，并且对于促进几位地球科学教师及其学生的研究需求至关重要。 洛杉矶将进一步研究开发多X型古气候，古环境图和古环境记录，特别是： b）使用石塔米木米和双壳类壳研究历史污染事件； c）开发和研究包括双壳类壳和珊瑚在内的生物碳酸盐群中的元素代理。洛杉矶系统还将推进高温地球化学研究，并通过岩浆混合，爆发前的岩浆含量以及火山岩和深层侵蚀的山带的温度计。 LA将用于本科研究，本科课程的实验室组成部分，并将推进对附近机构的两位女性预期教师的研究，并在其他机构中促进新的合作。该奖项反映了NSF的法定任务，并通过使用基金会的智能效果和宽阔的范围来评估，并通过评估值得评估。
