矿床位于湘桂粤北海西-印支坳陷区的东部边缘,与赣南后加里东隆起区毗邻.与成矿有关的岩体为主体期黑云母花岗岩和补充期二云母花岗岩组成的千里山燕山早期花岗岩.岩体侵入中、上泥盆统一套碎屑碳酸盐地层.矿床产于补充期细粒二云母花岗岩与泥盆系上统佘田桥组含砂泥质条带灰岩的接触带上.与成矿有关的蚀变主要是夕卡岩化和云英岩化.为一特大型的含有云母-石英网脉的夕卡岩型钨、钼、铋、锡、铍矿床.本文着重从元素地球化学角度探讨矿床成因,并
The deposit is located on the eastern margin of the Hercynian-Indosinian depression in the northern part of Hunan, Guangxi and Guangxi Provinces and adjoins the post-Galeon Uplift in southern Jiangxi Province. The metallogenetic rocks are mainly composed of biotite granite and complementary mica granite Early Yanshanian granites intruded into the middle and upper Devonian clastic carbonate strata, and the ore deposits originated from the fine granodiorite granites in the complementary period and the sandy shoal shale limestone in the upper member of the Devonian Shetianqiao Formation Contact zone.The metallogenic alteration is mainly skarnization and dolomitization, which is a large skarn-type tungsten, molybdenum, bismuth, tin and beryllium deposit containing mica-quartz network veins. This article focuses on the origin of the deposit from the perspective of elemental geochemistry
