U.S.-Argentina Cooperative Research on Determining Tectonic Subsidence History from Chronostratigraphy of Non-Marine Foreland Basin Strata, San Juan, Argentina

该奖项支持康奈尔大学的Teresa Jordan博士和阿根廷圣胡安国立大学的Felisa Bercowski博士在构造沉降史上的合作研究。阿根廷圣胡安省的出露地层中包含了晚新生代安第斯山脉的造山史。这种地层记录受构造作用的影响，可以用磁极性地层学和裂变径迹测年等现代技术来解释。将从现有的年代学研究中提取资料，并将结合岩石学、成岩学（沉积以来的物理和化学变化）和相学（外观和组成）研究。Bercowski教授将学习数据分析方法的理论和应用，这些方法将在她的实验室中应用。乔丹教授将有机会与一位生活在自然地质实验室的地质学家一起工作。这次合作为两位科学家提供了一个研究新生代非海相地层和构造史以及石炭纪和寒武纪地层和构造史的机会。这项资助是对美国国家科学基金会地球科学部提供的资金的补充，并扩展了Jordan博士和Bercowski博士之间的国际合作。

This award supports cooperative research on tectonic subsidence history between Dr. Teresa Jordan of Cornell University and Dr. Felisa Bercowski of the National University of San Juan, Argentina. The history of Andean mountain building in the late Cenozoic period is contained in exposed strata in the San Juan province in Argentina. This stratigraphic record was influenced by tectonic processes which can be interpreted by modern techniques such as magnetic polarity stratigraphy and fission track dating. Information will be extracted from existing chronological studies and will be coupled with petrographic, diagenetic (physical and chemical changes since deposition), and facies (appearance and composition) studies. Professor Bercowski will study theory and application of data analysis methods which will be applied in her laboratory. Prof. Jordan will have the opportunity to work with a geologist living in a natural geological laboratory. This collaboration provides an opportunity for both scientists to study Cenozoic non-marine stratigraphic and tectonic history as well as those of the Carboniferous and Cambrian ages. This grant is supplemental to funding provided by the Earth Sciences Division of NSF and extends the international cooperation between Dr. Jordan and Dr. Bercowski.
