0321278GrossmanThis Major Research Instrumentation (MRI) grant provides partial support for the purchase of an stable isotope ratio mass spectrometer (SIRMS) and automation systems that will allow (1) automated carbon and oxygen isotopic analyses of carbonate minerals, (2) oxygen and hydrogen isotopic analyses of water, and (3) automated carbon and nitrogen isotopic analyses of organic matter. A state-of-the-art micromilling system for high-resolution sampling of carbonates fossils will also be purchased. The new SIRMS will replace a 19 year old Finnigan MAT 251 in the Department of Geology & Geophysics at Texas A&M. The facility will also benefit faculty and students in Departments of Oceanography, Chemistry, and Anthropology and researchers affiliated with the Ocean Drilling Program. The new SIRMS will be employed for isotopic research including studies of Paleozoic and Tertiary paleoclimates, the biogeochemistry of anaerobic systems, carbonate petrology and human paleodiets. ***

这笔重大研究仪器(MRI)赠款为购买稳定的同位素比质谱仪(SIRMS)和自动化系统提供部分支持，这些系统将允许(1)碳酸盐矿物的自动化碳和氧同位素分析，(2)水的氧和氧同位素分析，以及(3)有机物的自动化碳和氮同位素分析。还将购买用于碳酸盐化石高分辨率采样的最先进的微型研磨系统。新的SIRMS将取代德克萨斯A&A&M地质与地球物理系已有19年历史的芬兰垫子251。该设施还将使海洋学、化学和人类学系的教职员工和学生以及与海洋钻探计划相关的研究人员受益。新的SIRMS将用于同位素研究，包括古生代和第三纪古气候、厌氧系统的生物地球化学、碳酸盐岩石学和人类古饮食的研究。***
