石英脉型钨多金属矿床的扇状成矿实例及找矿模型
Fan-shaped case and exploration model of quartz vein-type tungsten polymetallic deposits
摘要
Abstract
Quartz vein-type tungsten deposits are the most abundant types of tungsten deposits in China,yet the re-serves are being rapidly depleted.There is an urgent need to innovate the exploration model to guide break-throughs in finding new deposits.The article,which combines over two decades of exploration practice,con-structs a new exploration model for quartz vein-type tungsten deposits through a detailed analysis of fan-shaped mineralization instances.This model emphasizes that the ore-bearing fractures are of magmatic dynamic origin and are distributed in a fan-shaped pattern at the top of the granite.The fan-shaped mineralization system is be-lieved to have formed when post-magmatic hydrothermal fluids filled the fractures as they were opening.The model also proposes geological,geochemical,and geophysical indicators for"exploration around the granite","exploration around known deposits",and"exploration around the deposits for granite",guiding the deployment of exploration survey projects at the deposit scale.To date,this model has been validated in the Heshangtian W-Sn deposit in Guangdong Province,Shanhu W-Sn deposit and Shedong W-Mo deposit in Guangxi Province,as well as the Pangushan W-Bi deposit in Jiangxi Province,and has achieved remarkable results in exploration.关键词
