Acquisition of a Carbon/Sulfur Determinator System for Sedimentary Materials

利用这笔赠款，奥本大学地质和地理系将获得一套碳/硫测定仪系统，用于分析沉积物和沉积岩中的有机碳和硫成分。购买这一设备将取代现在不能使用和过时的碳分析仪，这将有助于维护和加强现有的研究和教学计划，这些计划涉及对细粒沉积材料的详细表征，以及对其沉积环境和碳氢化合物来源潜力的评估。首席研究员和他的学生正在并将参与研究项目，这些项目将从准确测量沉积有机碳和/或硫含量中受益匪浅。这些方案包括：(1)重建海洋盆地古氧气史；(2)评价韵律层状远洋碳酸盐岩层序中沉积旋回性的成因机制；(3)被动边缘序列的层序地层学和海平面动力学解释；(4)古代近岸和边缘海洋环境和过程的分析。***

0139790SavrdaWith funds from this grant, the Department of Geology and Geography at Auburn University will acquire a carbon/sulfur determinator system for the analysis of organic carbon and sulfur components in sediments and sedimentary rocks. Acquisition of this equipment, which will replace a now-inoperative and obsolete carbon analyzer, will help maintain and enhance existing research and teaching programs that involve detailed characterization of fine-grained sedimentary materials and evaluation of their depositional environments and their hydrocarbon-source potential. The principal investigator and his students are and will be involved in research programs that will benefit significantly from accurate measurement of sedimentary organic carbon and/or sulfur contents. These programs involve (1) reconstruction of marine basin paleo-oxygenation histories; (2) evaluation of causal mechanisms for depositional cyclicity in rhythmically bedded pelagic carbonate sequences; (3) sequence stratigraphy of passive-margin successions and interpretation of sea-level dynamics; and (4) analysis of ancient nearshore and marginal marine environments and processes. ***
