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

描述：该奖项是为了支持爱达荷州波卡特洛爱达荷州立大学地球科学系Shuhab Khan博士，堪萨斯州劳伦斯堪萨斯大学地质系J. Douglas Walker博士和巴基斯坦白沙瓦白沙瓦大学地质卓越中心Mohammed T. Shah博士之间的合作项目。研究人员计划：(1)在巴基斯坦喜马拉雅山脉的Kohistan地块北部开展野外工作，对Teru- shandur和Teru- yasin地区的Teru火山岩和伴生岩石进行地球化学和同位素测年（U-Pb）和取样；(2)开展地区年代学、同位素调查项目；(3)利用星载数据和实地观测，对整个科伊斯坦地区北部的Teru火山进行测绘。研究结果将有助于进一步认识晚期火山的年龄、区域分布、同位素和地球化学亲缘关系及其对喜马拉雅西北地区演化、科希斯坦西北地区碰撞前后构造热史、科希斯坦地体特别是喜马拉雅地区的安第斯边缘和碰撞后历史的影响。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Kohistan弧序列的岩性测绘技术，该技术有可能用于绘制喜马拉雅地区大部分无法进入的大片地区。研究范围：拟开展的研究项目建立在研究人员获得的特鲁—山都地区的初步年龄、地球化学和同位素结果的基础上，以及主要研究人员与明尼苏达大学现有的合作关系的基础上，研究成果将有助于对碰撞造山作用的广泛理解。这项提议的工作将对伊利诺伊州立大学和宾夕法尼亚大学的教育产生影响，因为两所大学的研究生都将参与这项研究。他于2001年获得博士学位，目前在爱达荷州立大学（Idaho State University）开始学术和研究生涯。他将得到英国Walker博士实验室优秀的技术分析专家的支持。一位巴基斯坦科学家将在I.S.U.度过两个月，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.
