Strontium and Carbon Isotope Stratigraphy of the Petroleum-Rich Upper Cretaceous La Luna Formation, Venezuela

0120120富拉加该奖项将支持北卡罗来纳大学教堂山分校的保罗·D·富拉加博士和蒂莫西·J·布拉洛尔博士与玛丽亚·洛伦特以及委内瑞拉中央大学的埃格利·J·萨帕塔合作进行一项研究，以确定委内瑞拉主要石油来源拉露娜组的锶和碳同位素地层学。该提案计划提供一个化学地层学框架(基于锶和碳同位素)，以便对委内瑞拉的La露娜组剖面进行对比，从而更好地了解其沉积环境和这些富碳有机矿床的积累。这一地层学将是即将完成的地层生物地层学-化学地层学年龄模型的组成部分。这项调查将加强我们对控制整个地球历史上被称为“黑色页岩”的海洋白垩纪有机富碳沉积物(CORG)积累过程的理解。

0120120FullagarThis award will support Drs. Paul D. Fullagar and Timothy J. Bralower, University of North Carolina at Chapel Hill, in collaboration with Maria Lorente, and Eglee J. Zapata, Universidad Central de Venezuela, for a study to determine the strontium- and carbon-isotope stratigraphy for La Luna Formation, a major source of petroleum in Venezuela. The proposal plans to provide a chemostratigraphy framework (based on strontium and carbon isotopes) that would allow correlation of La Luna Formation sections in Venezuela, and thus a better understanding of its environment of deposition and the accumulation of these organic carbon-rich deposits. This stratigraphy will be an integral part of a nearly completed biostratigraphic-chemostratigraphic age model for the formation. The investigation will enhance our understanding of the processes that control the accumulation of marine Cretaceous organic carbon-rich sediments (CORG) known as "black shales" deposits throughout earth history.
