US-Pakistan Cooperative Research: Toward a Better Understanding of the Pakistani Himalayas: Inferences from Remote Sensing, Field, Age and Isotopic Data

0242950Walker描述：该奖项是为了表彰爱达荷州州立大学(I.S.U)地质科学系Shuhab Khan博士、堪萨斯州劳伦斯市堪萨斯大学地质学系J.Douglas Walker博士和巴基斯坦白沙瓦大学地质卓越中心Mohammed T.Shah博士之间的合作项目。调查人员计划：(1)在巴基斯坦喜马拉雅山脉科希斯坦地体北部进行野外工作，为Teru-Shandur和Teru-牙生地区的Teru火山岩及伴生岩石绘制地图和样品，以便进行地球化学和同位素测年；(2)在该地区进行年代学和同位素调查；(3)利用星载数据和野外观测，对整个Kohistein地体北部的Teru火山岩进行测绘。这些结果将有助于加深对晚期火山岩的年龄、面积分布、同位素和地球化学亲和力及其对喜马拉雅西北地区演化、科希斯坦西北部同碰撞和碰撞后构造热史、特别是科希斯坦地体和整个喜马拉雅山脉的安第斯边缘和碰撞后历史的意义的理解。研究人员计划利用最近部署的星载ASTER传感器的数据，开发和验证科希斯坦弧层序的岩性填图技术，这些技术可能被用来绘制喜马拉雅山脉大部分难以接近的广大地区的地图。范围：拟议的研究计划建立在调查人员获得的Teru-Shandur地区的初步年龄、地球化学和同位素结果，以及首席调查员与P.P.之间现有的合作关系的基础上。研究成果将有助于更广泛地理解碰撞造山作用。这项拟议的工作将对伊利诺伊州立大学和南加州大学产生教育影响，因为这两所大学的研究生都将参与这项研究。Khan博士于2001年获得博士学位，目前在爱达荷州立大学从事学术和研究工作。他将得到沃克博士英国实验室出色的技术分析专业知识的支持。一名巴基斯坦科学家将在I.S.U工作两个月，帮助处理和解释图像，并准备一份手稿。

0242950WalkerDescription: This award is for support of a cooperative project between Dr. Shuhab Khan, Department of Geosciences, Idaho State University (I.S.U.), Pocatello, Idaho, Dr. J. Douglas Walker, Department of Geology, University of Kansas (U. of K.), Lawrence, Kansas and Dr. Mohammed T. Shah, Center of Excellence in Geology, University of Peshawar (U. of P.), Peshawar, Pakistan. The investigators plan to: (1) conduct field work in the northern Kohistan terrane in the Pakistani Himalayas to map and sample for geochemical and isotopic dating (U-Pb) of the Teru volcanics and associated rocks from the Teru-Shandur and Teru-Yasin areas; (2) conduct a program of geochronologic and isotopic investigations in the area; (3) to run a mapping exercise for the Teru volcanics in the entire northern Kohistan terrane by using space-borne data and field observations. The results will improve understanding of the age, areal distribution, and isotopic and geochemical affinities of the late-stage volcanics and their implications for the evolution of the northwest Himalayas, the syn- and post-collisional tectonothermal history of northwest Kohistan, and the Andean margin and post-collisional history of the Kohistan terrane in particular and the Himalayas in general. The investigators plan to develop and validate techniques for lithologic mapping of Kohistan arc sequences by using data from the recently deployed space-borne ASTER sensor, which can potentially be used to map vast areas in the Himalayas that are largely inaccessible.Scope: The proposed research program builds on preliminary age, geochemical, and isotopic results in the Teru-Shandur area, which were obtained by the investigators, as well as on the existing collaborative relationship between the principal investigator and U. of P. The research results will contribute to the broad understanding of collisional orogenesis. The proposed work will have an educational impact both at I.S.U. and the U. of P., as graduate students from both universities will be involved in the research. Dr. Khan received his Ph.D. in 2001 and is starting an academic and research career at Idaho State University. He will be supported by the excellent technical analytical expertise in Dr. Walker's laboratory the U. of K. A Pakistani scientist will spend two months at I.S.U. to help in the processing and interpreting of images and in the preparation of a manuscript.
