摘要
赣南具"世界钨都"之称,特别是易识别、易选的石英脉型钨矿床闻名遐尔。近20年来,在开采开发石英脉型钨矿的同时,人们也发现了一种新的钨矿类型,即八仙脑式的破碎蚀变岩带-石英脉复合型钨矿。本文通过对八仙脑钨矿成矿特征的研究,提出了"五层楼+地下室"的找矿新模型,以期对该区的新一轮钨多金属矿找矿有所启迪与帮助。该模型已经对老庵里、金银庵等大、中型钨矿的勘探起了重要的指导作用。
The Gannan area （southern Jiangxi province） is famous for tungsten, hence nicknamed the tungsten capital of the world, especially quartz vein-type tungsten deposits, which are easily recognized and mined. After 20 years＇ explortation here, a new type of tungsten deposit, Baxiannao-type brecciatied alterated zone quartz-vein-type composite tungsten deposit has been recognized. The paper studies ore-forming features of this kind in detail, and proposes a new model Five Floors q-Basement for this kind of deposit, which is expected to give more help to next new-round exploration for tungsten polymetals deposits in this area and also provides important guidance for exploration in large-or medium-scale tungsten deposits such as Lao＇anli and Jinyin＇an.
