Acquisition of Basic Analytical Equipment for the Study of Rocks, Groundwaters, and other Aqueous Solutions

该合同提供了购买直接耦合等离子体光谱仪（DCP）和分光光度计（SPM）所需资金的50%，用于分析实验室实验中产生的自然地质和合成流体。该大学承诺提供额外的资金，使此次收购成为可能。这些设备将被安置在南卫理公会大学地质科学系，PI和他的学生以及其他一些教员和研究生将广泛使用这些设备。DCP和SPM将用于确定大块岩石和地下水的化学成分、矿物的溶解度和矿物流体的反应速率。使用该设备的教师和学生将获得化学分析，这将是一系列研究项目的重要组成部分。这些项目将包括研究：风化和土壤形成，全球二氧化碳循环，不同地形的古水文，变质作用和地幔交代作用期间的流体-岩石相互作用。

This award provides 50% of the funds needed for the acquisition of a directly coupled plasma spectrometer (DCP) and a spectrophotometer (SPM) to analyze natural geologic and synthetic fluids produced in laboratory experiments. The university is committed to provide the additional funds required to make this acquisition possible. This equipment ,which will be housed in the Department of Geological Sciences at Southern Methodist University, will be used extensively by the PI and his students and by a number of other faculty and graduate students. The DCP and SPM will be used to determine chemical compositions of bulk rocks and groundwaters, solubilities of minerals, and mineral fluid reaction rates.Faculty and students using this equipment will be obtaining chemical analyses that will be an important component of a diverse set of research projects. These projects will include studies of : weathering and soil formation, global cycling of carbon dioxide, paleohydrology in different terrains, and fluid-rock interaction during metamorphism and mantle metasomatism.
