Origin and Economic Significance of Neoproterozoic Ophiolites in the Southern Eastern Desert, Egypt: US-Egypt Joint Science Program

该项目将研究埃及东南部沙漠的蛇绿岩（海洋岩石圈碎片），并利用这些信息更好地了解具有经济意义的矿藏。前人的研究表明，弧前蛇绿岩模式对了解中东部沙漠蛇绿岩组合非常有用，PIs建议对东部沙漠南部的蛇绿岩进行类似的研究。重点将放在了解与埃及最明确的缝合带Allaqi-Heiani-Gerf缝合带相关的蛇绿岩，该缝合带可以连续追溯到从纳赛尔湖到苏丹边境以北的红海。更广泛的影响包括社会相关性，因为科学目标支持经济目标，即了解蛇绿岩对经济矿床的类型和位置施加的控制。此外，这将为更广泛的边际社区带来各种各样的科学利益。本项目由美国国家科学基金会国际科学与工程办公室共同资助。

This project will study ophiolites (fragments of oceanic lithosphere) in the South Eastern Desert of Egypt and use this information to better understand economically significant mineral deposits. Previous efforts have shown that application of the fore-arc ophiolite mode to be very useful for understanding the ophiolitic assemblages in the Central Eastern Desert, and the PIs propose to similarly study ophiolitic rocks in the southern Eastern Desert. Emphasis will be placed on understanding ophiolites associated with the best defined suture zone in Egypt, the Allaqi-Heiani-Gerf suture, which can be continuously traced from Lake Nasser to the Red Sea just north of the Sudanese border. The Broader impacts include societal relevance since the scientific objective supports an economic objective of understanding what if any controls the ophiolite exerted on the type and location of economic mineral deposits. Additionally there will be a diverse scientific benefit to the broader MARGINS community.This project is co-funded by the NSF Office of International Science and Engineering.
