Production of Lithologic and Structural Maps from Digital Landsat Thematic Mapper Data Over the Eastern Desert, in Egypt

摘要叙述描述：该提案支持密苏里州圣路易斯市华盛顿大学的Mohamed Sultan博士和Raymond Arvidson博士以及埃及地质调查局总干事Atef Dardir博士的合作，艾因沙姆斯大学的Baher El Kaliouby博士和英国地质调查局的Eugene O‘Connor博士。该项目将建立在NASA支持的Sultan博士和Arvidson博士正在进行的研究工作的基础上，他们在研究工作中确定，专题测图仪数据在生成系统的地质图方面非常有用。所要求的国家科学基金支助的一部分计划用于购买四个数字陆地卫星专题地图(TM)场景。这些场景与调查人员目前持有的三个TM场景相结合，将为埃及东部沙漠所有晚期元古代露头提供专题地图覆盖。从这七个场景中，将生成1：150K和1：50K比例的彩色和黑白复合打印。这些合成材料将用于生成解释性地图，描绘东部沙漠的岩性、构造和矿产资源。这些产品将交付给埃及地质调查局、艾因沙姆斯大学和英国地质调查局(用于监督绘图计划)，以检查基于TM的说明的有效性，以及关于如何改进初始地图的说明。第一批TM产品将由该项目改进，并由埃及两个机构用作底图，以生成1：250K比例尺的区域地图和1：50K比例尺的本地地图。范围：这项建议是美国和埃及科学家在英国地质学家的帮助下，开发一套完整的埃及东部沙漠地质图的机会。这些地图将为科学家提供宝贵的补充信息，以便对东部沙漠中存在的阿拉伯-努比亚盾中元古代晚期大陆生长过程进行实地研究。较小比例尺地图的较高分辨率将确定更明确地研究该地区的地质史和经济潜力所需的细节。这些最终地图虽然增加了对埃及东部沙漠努比亚盾构造演化的了解和理解，但可能会为绘制世界其他地方干旱大陆上鲜为人知的地区地图提供重要帮助。这项建议确实符合促进国际科学知识交流的发展中国家科学计划的目标，并有助于促进发展中国家的科学发展。

ABSTRACT NARRATIVE Description: This proposal supports the collaboration of Drs. Mohamed Sultan and Raymond Arvidson of Washington University, St. Louis, Missouri, and Dr. Atef Dardir, Director General of the Geological Survey of Egypt, Dr. Baher El Kaliouby of Ain Shams University and Dr. Eugene O'Connor of the British Geological Survey. The project will build on the ongoing NASA supported research work of Drs. Sultan and Arvidson, where they have determined that thematic mapper data is very useful in generating systematic geological maps. A portion of the requested NSF support is planned for the purchase of four digital Landsat thematic mapper (TM) scenes. These scenes, when joined with the current set of three TM scenes held by the investigators, will provide thematic mapper coverage for all Late Proterozic outcrops in the Eastern Desert of Egypt. From these seven scenes, color and black and white composites prints at scales of 1:150K and 1:50K will be generated. Those composites will used to generate interpretative maps depicting the lithology, structures and mineral resources of the Eastern Desert. These products will be delivered to the Egyptian Geological Survey, Ain Shams University and British Geological Survey (for supervision of the mapping program) for checking the validity of TM based intrepretations and instructions on ways to refine the initial maps. The first TM products will be refined by the project and used as base maps by the two Egyptian institutions to generate regional maps on the scale of 1:250K and local maps to the scale of 1:50K. Scope: This proposal is an opportunity for U.S. and Egyptian scientists, aided by British geologists, to develop a set of complete geological maps of the Eastern Desert of Egypt. These maps will give scientists valuable additional information to pursue field studies of the continental growth processes in the Late Proterozic Era in the Arabian-Nubian Shield existing in the Eastern Desert. The greater resolution of the smaller scale maps will define the details necessary for more definitive studies of geological history and economic potenial of the region. These final maps, while adding to the knowledge and understanding of the tectonic evolution of the Nubian Shield in the Eastern Desert of Egypt, may provide significant assistance in mapping less known areas of arid continents elsewhere in the world. This proposal does meet the objectives of the Science in Developing Countries Program of advancing the international exchange of scientific knowledge and does cointribute to the enhancement of science in a developing country.
