| 摘 要： | 西昆仑-喀喇昆仑位于特提斯构造域北缘,该地区通过多年的基础地质调查和找矿勘查,已在铁矿、铅锌矿、锰矿等找矿方面实现了重大突破。项目组最近三年通过多次野外勘查、系统取样与室内化验分析,确认在新疆和田县喀喇昆仑腹地白龙山新发现了一处超大型锂铷多金属矿床。该矿床为花岗伟晶岩型,目前已确定含矿伟晶岩墙规模为长度3750 m,宽度46~165 m,其中I号矿带由3个巨大矿体组成,长990~1230 m,厚61.86~115.85 m,走向110°~120°,倾角65°~80°。3个主矿体Li_2O平均品位1.26%~1.60%,Rb_2O平均品位0.10%~0.12%,估算334资源量Li_2O为345.7647万吨,Rb_2O为17.682万吨,达到超大型规模,有望成为一个世界级规模的巨型锂矿床。白龙山超大型锂铷多金属矿床的发现,为整个西昆仑-喀喇昆仑地区稀有金属矿产找矿实现了重大突破,对喀喇昆仑锂稀有金属成矿带的确立奠定了坚实的基础,使该地区有望成为我国一个新的重要的锂资源基地。

| Abstract: | The West Kunlun-Karakorum Orogenic Belt is located in the northern most part of the Tibet Plateau. Great progresses have been made in metallogenic study and prospecting of iron, lead, zinc, and manganese ore deposits in the last few years. However, even though lithium is one of the most important metal resources in the region, the importance of lithium polymetallic mineralization has largely been ignored. Through three years of systematic field exploration and laboratory analyses, we have found a superlarge Li-Rb rare metal pegmatite deposit in the Bailongshan area of the Karakorum Mountains, Hetian County, Xinjiang. It is a pegmatite type Li-Rb deposit, and a large spodumene-containing pegmatite wall (length>3750 m, width 46?165 m) has been delineated. The deposit consists of three main ore bodies situated in the ore-bearing pegmatite wall (length 990?1230 m, thick 61.86?115.85 m). The resource reserves for Li2O and Rb2O are estimated to be 3.45 million tons and 176,000 tons, respectively. It is reasonable to infer that it will turn out to be a world-scale lithium deposit. The discovery of the Bailongshan superlarge Li-Rb rare metal pegmatite deposit is a great breakthrough of ore prospecting in the Western Kunlun?Karakorum region. The discovery also unveiled a potential Karakorum lithium rare metal metallogenic belt, which will possibly become a new important lithium resource base in China. |
