摘要:
      在整理湖南73处钨矿床资料的基础上,通过成矿区带划分、控矿因素归纳、重要钨矿成矿区带的成矿密度和成矿强度的定量分析,将湖南钨矿区带划分为5个Ⅲ级成矿区(带)、12个Ⅳ级成矿亚带(区)、20个矿集区。梳理Ⅳ级各成矿亚带(区)的矿床分布特征可知,万洋山—诸广山成矿区(Ⅲ-83-5)钨矿床数量最多,资兴—宜章成矿区(Ⅲ-83-4)的成矿强度最强,达212.74 t/km2。各矿集区矿床分布特征显示,千里山—骑田岭钨矿集区(Ⅲ-83-4-a)有9处钨矿床,矿床数量最多;瑶岗仙钨矿集区(Ⅲ-83-5-c)成矿密度、成矿强度均位居矿集区首位。燕山期为钨矿成矿的高峰期,该期形成的WO3累计查明资源量占全省累计查明资源量的78.78%。

Abstract:
      Based on the data of 73 tungsten deposits in Hunan, through the classification of metallogenic zones, the induction of ore-controlling factors, the quantitative analysis of metallogenic density and metallogenic intensity of important tungsten ore belts, Hunan tungsten ore belts are divided into 5 Ⅲ-level metallogenic areas (belts), 12 Ⅳ-level metallogenic subbelts (subzones), and 20 ore concentration areas. The deposit distribution characteristics of Ⅳ-level metallogenic subbelts (subzones) reveal that Wanyangshan-Zhuguangshan metallogenic area (Ⅲ-83-5) has the largest number of tungsten deposits, and Zixing-Yizhang metallogenic area (Ⅲ-83-4) has the strongest metallogenic intensity, up to 212.74 t/km2. The deposit distribution characteristics of each ore concentration area show that there are 9 tungsten deposits in Qianlishan-Qitianling tungsten concentration area (Ⅲ-83-4-a), and its number of tungsten deposits is the largest. Yaogangxian tungsten ore concentration area (Ⅲ-83-5-c) has the highest metallogenic density and intensity. The tungsten ore-forming peak occurred in the Yanshanian period, and the proven accumulated WO3 reserves formed during this period account for 78.78% of the total proven reserves of Hunan Province.
