US-Bangladesh Cooperative Research Basin-Wide Stratigraphy of Cenozoic Sequences in the Bengal Basin

项目描述：本项目旨在支持阿拉巴马州奥本大学地质系Ashraf Uddin博士和孟加拉国达卡大学地质系M. Mustafa Alam博士的合作研究项目。这些科学家计划进行实地研究并收集有代表性的沉积物样本，以便调查孟加拉盆地始新世到第四纪的序列，为全盆地的对比和邻近山带的构造历史寻找矿物学和地质年代学证据。他们将确定最有可能限制全盆地相关性的技术。这些技术将包括对材料的裂变径迹分析、对若干剖面的磁地层研究和重矿物研究。由此产生的地层格架将用于评估孟加拉盆地的历史，包括石油潜力和正在进行的大陆碰撞的宝贵记录。范围：阿什拉夫·乌丁博士是一名刚毕业的博士，他在喜马拉雅-孟加拉盆地的沉积学演化历史方面做了重要的研究。在这个项目中，他将与几位资深学者合作，他们在一些将要使用的技术方面具有丰富的经验。其中一位是尼尔·奥普戴克，他将研究磁地层学，他也曾在西喜马拉雅山研究中使用过这种方法。另一位是约翰·加弗（John Garver），他将监督裂变径迹分析，他最近在相当复杂的裂变径迹分析领域拥有丰富的经验，该领域将碎屑颗粒年龄与源地联系起来。来自阿拉巴马大学的一名美国研究生和至少一名来自达卡大学的研究生也将参与这项研究，并将获得国际科学合作的经验。达卡大学地质系将为该项目提供设施和支持。该项目将受益于双方可获得的互补专业知识和设施。该项目符合INT标准，支持对美国和外国互惠互利的有价值的合作研究。本项目由国际项目部和地球科学部资助。

0117405UddinDescription: This project is to support a cooperative research project by Dr. Ashraf Uddin, Department of Geology, Auburn University, Auburn, Alabama and Dr. M. Mustafa Alam, Department of Geology, University of Dhaka, Dhaka, Bangladesh. These scientists plan to conduct field research and to collect representative sediment samples in order to investigate Eocene through Quaternary sequences of the Bengal basin for mineralogical and geochronological evidence for basin-wide correlation and of the tectonic history of the adjacent mountain belts. They will identify techniques with the best potential for constraining basin-wide correlation. The techniques will include fission-track analysis of materials, magentostratigraphic study on several sections, and heavy-mineral studies. The resulting stratigraphic framework will be used to evaluate the Bengal basin history, with implications for both petroleum potential and a valuable record of the ongoing continental collision.Scope: Dr. Ashraf Uddin is a recent Ph.D. graduate who has made significant research on the sedimentology of the Himalayan-Bengal basin evolutionary history. In this project he will be collaborating with several senior scholars with extensive experience in some of the techniques to be used. One is Neil Opdyke, who will be working on the magnetostratigraphy, and who has also used this worked on the western Himalayas study. Another is John Garver, who will supervise the fission-track analysis, has extensive, recent experience in the rather complicated area of fission-track analysis that relates detrital grain ages to source terranes. One US graduate student from the University of Alabama and at least one from the University of Dhaka will also participate in this research and will gain experience in international scientific collaboration. The Department of Geology at the U. of Dhaka will provide facilities and support for the project. The project will benefit from the complementary expertise and facilities available to the two sides. This project meets INT criteria for supporting meritorious collaborative research of mutual benefit to the US and the foreign country. This project is funded by the Division of International Programs and the Division of Earth Sciences.
