Petrology and Geochemistry of Economic Minerals and Their Host Rocks in the Besham Area of Northern Pakistan

描述：该项目支持P.I.John W.Shervais博士和他的巴基斯坦博士生M.Tahir Shah在巴基斯坦进行的地质实地研究，以及Shah先生在东华盛顿大学M.Ikrauddin博士的实验室进行的实验室研究。研究目标包括：1)评价金、银在基本金属铅锌矿体内及邻近地区的分布，以及贵金属含量与基本金属矿石品位的关系；2)评价引路元素在高级变质地体中寻找火山成因矿床的有效性；3)根据新的地球化学资料评价巴基斯坦贝沙姆地区铅锌矿床的成因。沙阿将在巴基斯坦的拉合尔和帕赞铅锌硫化物矿床这两个代表单一原生矿体的地区采集样本，这些原生矿体在构造上已被抵消。他将在伊克拉穆丁博士的监督下，在东华盛顿大学对这些样本进行地球化学分析。研究范围：除了巴基斯坦的研究生，南卡罗来纳大学和东华盛顿大学的科学家以及巴基斯坦白什瓦大学的地质学家将汇集在一起，他们对巴基斯坦的地质有丰富的经验。这项工作可能有助于增进对具有经济价值的矿物的地球化学的了解，并加强巴基斯坦研究生的科学能力和为该国的技术和经济发展作出贡献的潜力。

Description: This project supports geological field research in Pakistan by the P.I. Dr. John W. Shervais and his Pakistani doctoral student, M. Tahir Shah; and laboratory research by Mr. Shah in the laboratory of Dr. M. Ikramuddin at Eastern Washington University. The research objectives include: 1) assessment of the distribution of gold and silver within and adjacent to the base metal lead-zinc ore bodies and the correlation between precious metal concentrations and base metal ore grades; 2) assessment of the usefullness of pathfinder elements in locating volcanogenic ore deposits in high grade metamorphic terrains, and 3) evaluation of the origin of the lead-zinc deposits in the Besham area of Pakistan in light of the new geochemical data. Mr. Shah will collect samples in Pakistan in two areas that represent a single primary ore body that has been offset structurally, the Lahore and the Pazang lead-zinc sulfide deposits. He will conduct geochemical analysis of these samples at Eastern Washington University under supervision of Dr. Ikramuddin. Scope: The research will bring together, in addition to the Pakistan graduate student, scientists from the University of South Carolina, and Eastern Washington University, and geologists from the University of Peshwar in Pakistan who have extensive experience in the geology of Pakistan. The work is likely to lead to improvement in the understanding of the geochemistry of minerals of economic value, and to enhance the scientific capabilities of the Pakistani graduate student and his potential to contribute to the technical and economic development of his country.
