摘要:
帕米尔高原是由喜马拉雅山脉、喀喇昆仑山脉、昆仑山脉、天山山脉、兴都库什山脉交汇于此形成的一个巨大的山结.由于其特殊的地质构造位置和复杂的构造演化历史,形成了良好的成矿地质背景条件.依据中塔两国政府"双方地学领域科技合作谅解备忘录"精神,中塔两国合作组织实施了"塔吉克帕米尔成矿带地球化学调查"工作.完成3万km2地球化学填图任务,建立了工作区地球化学数据库,编制了系列地球化学图件.应用地球化学分析方法回答了测区资源潜力评价有关的地学问题,在此基础上编制了Ag、Au、Pb-Zn等8个元素(组)找矿预测图,共圈定各类找矿预测区136个.同时,也从地球化学角度解决了许多地质问题.为开展塔吉克帕米尔地区地质科学研究,了解帕米尔地区优势资源种类、分布地域、资源潜力等评价信息,快速缩小找矿靶区,实现找矿突破,改变地区资源分布格局等工作提供了可靠而丰富的地球化学基础资料.
Abstract:
The Pamir Plateau was formed by a series of mountain ranges such as the Himalaya, Karakoram, Kunlun, Tianshan and Hindu Kush. Its unique geological location and complex tectonic evolution provide good metallogenic and geological conditions for the plateau. According to the Memorandum of Understanding on Geoscientific Cooperation signed by and between the Ministry of Foreign Affairs of the People's Republic of China and the Ministry of Foreign Affairs of the Republic of Tajikistan on November 25, 2010, both parties organized and implemented "geochemical surveys in the Pamir metallogenic belt in Tajikistan". Geochemical mapping for an area of 30,000 square kilometers has been completed;a regional geochemical database has been established;and a series of geochemical maps have been made. The geological problems related to resource potential assessment in the area have been answered by geochemical means On this basis, the ore-prospecting map for 8 elements (groups) such as Ag, Au and Pb-Zn have been completed;136 ore-prospecting areas have been delineated;and many geological problems have been solved. These achievements provide reliable and abundant basic geochemical data for undertaking geoscientific research, understanding potential evaluation information (such as species, geographical distribution and potential of high-quality resources), quickly narrowing the range of ore-prospecting targets, achieving ore-prospecting breakthroughs and changing the resource distribution patterns in the Pamir area in Tajikistan.
