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.
