新疆东昆仑白干湖钨地球化学块体的确立及意义

新疆东昆仑是我国西部地质工作程度较低地区之一,白干湖钨地球化学块体的确定及白干湖钨锡矿床的发现成为该区矿产勘查中突破性的进展.文章概述了白干湖钨地球化学块体的地质、矿产及地球化学特征.对该块体与成矿的关系进行了探讨,认为钨地球化学块体为白干湖钨锡矿床的形成提供了丰富的成矿物质,钨的成矿与岩浆的演化有着密切的成因关系.指出白干湖钨锡矿床有望成为超大型矿床,新疆东昆仑地区有望成为我国一个新的钨矿远景区和新的钨矿产区.

DISCOVERY AND SIGNIFICANCE OF BAIGANHU W GEOCHEMICAL BLOCK IN THE EASTERN KUNLUN MOUNTAIN, XINJIANG

Previously mineral resources exploration work had been hardly done in the eastern Kunlun area of Xinjiang. Major advances including discovery of Baiganhu W and Sn deposit and Baiganhu W geochemical block have been made in recent years. Geological and geochemical characteristics of Baiganhu W geochemical block are briefly introduced. Relations between geochemical block and ore formation have been analyzed. Baiganhu W geochemical block supplies abundant ore - forming materials for Baiganhu W and Sn deposit. Formation of W ores is related with evolution of granitic magma. It is suggested that Baiganhu W and Sn deposit a potential to become a superlarge deposit, and the eastern Kunlun mountain area also has a potential to be a new important ore prospecting and producing area for tungsten.
