This proposal requests funds to permit Dr. Johan C. Varekamp, Department of Earth and Environmental Sciences, Wesleyan University, to pursue with Dr. Adjat Sudradjat and staff members, Volcanological Survey of Indonesia, for a period of 24 months, a program of research on the geophysics and geology of the East Sunda and Banda Arcs, strings of small, active volcanoes, north and east of Timor in Indonesia. By combining field studies of volcanic stratigraphy with petrography, mineral and glass analyses, volcanic gas geochemistry, and bulk rock element and isotope geochemistry, the collaborators will obtain new insights into the origin and development of the enigmatic potassic arc volcanoes in this region. They also will trace the genetic relations between these volcanoes and neighboring calcalkaline volcanoes. Studies of the volcanic gases and hydrothermal fluids will provide an assessment of geothermal potential of these arcs. The collaborators are highly respected scientists with a record of successful research collaboration in the region to be studied. This project is relevant to the objectives of the Science in Developing Countries Program which seeks to increase the level of cooperation between U.S. scientists and engineers and their counterparts in developing countries through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.

这一建议要求资金允许约翰·C博士。Varekamp，地球和环境科学系，卫斯理大学，追求与Dr. Sudradjat和工作人员，印度尼西亚火山调查，为期24个月，对东巽他和班达弧，小，活火山串，在印度尼西亚帝汶岛北部和东部的地球物理学和地质研究方案。通过将火山地层学的野外研究与岩石学、矿物和玻璃分析、火山气体地球化学以及岩石元素和同位素地球化学相结合，合作者将对该地区神秘的钾质弧火山的起源和发展获得新的见解。他们还将追踪这些火山与邻近的钙碱性火山之间的遗传关系。对火山气体和热液的研究将提供对这些弧的地热潜力的评估。合作者是备受尊敬的科学家，在所研究的区域有成功的研究合作记录。该项目与发展中国家科学方案的目标有关，该方案旨在通过交流科学信息、思想、技能和技术以及通过在互利问题上的合作，提高美国科学家和工程师与发展中国家同行之间的合作水平。
