摘要:

镇安西部钨矿集区位于南秦岭构造带,区内出露地层主要为古生代碳酸盐岩,岩浆岩主要为胭脂坝、懒板凳和四海坪花岗岩体。区内断裂发育,为钨矿成矿提供了导矿构造和容矿构造。近EW走向断裂破碎带内出现了典型的矽卡岩型钨矿化,此外NE-NNE走向的石英脉型钨矿化同样发育,二者共同构成了本区的主要钨钼矿化类型。通过对矿集区棋盘沟和核桃坪等典型钨矿床进行野外调查及室内研究,取得以下认识:(1)矿集区内控矿构造为近EW向与NE-NNE向2组不同方向的构造裂隙;(2)根据该区构造背景,矿集区内NE-NNE构造裂隙是晚印支—燕山期构造活动形成的,近EW向构造裂隙则主要是印支期构造活动形成的,相对于燕山期钨钼成矿期近EW向断裂为成矿前构造,而NE-NNE向断裂裂隙属于成矿期构造;(3)矿集区内钨矿化类型以热液石英脉型和矽卡岩型为主,其中石英脉型主要受NE-NNE向断裂及节理裂隙控制,矽卡岩型主要受近EW向断裂破碎带控制。

Abstract:

The western tungsten deposit area of Zhen’an is located in the south Qinling tectonic belt.The main exposed strata in the area are Paleozoic carbonate rocks.The magmatic rocks are mainly rouge dams,lazy benches and Sihaiping granite bodies.The fault development in the area provides a ore-conducting and ore-bearing structure for the tungsten ore formation in the area.The skarn-type tungsten mineralization occurred in the near EW strike fracture zone.In addition,the NE-NNE-oriented quartz vein-type tungsten mineralization also developed,which together constitute the main tungsten-molybdenum mineralization type in this area.This paper mainly conducts field investigation and indoor research on typical tungsten deposits such as Qipangou and Hetaoping in the mining area,and has obtained the following knowledge:(1)The ore-controlling structure in the ore-concentrating area is a tectonic fracture in two different directions from the EW and the NE-NNE direction.(2)According to the tectonic background of the area,the tectonic fractures in the NE-NNE of the ore-concentrating area are formed by the Late Indosinian-Yanshanian tectonic activities,and the near-east tectonic fractures are mainly formed by the Indosinian tectonic activities.Compared with the Yanshanian tungsten-molybdenum ore-forming period,the near-east-west fault is a pre-mineral structure,while the NE-NNE fault fracture belongs to the metallogenic structure.(3)The type of tungsten mineralization in the ore-concentrating area is mainly composed of hydrothermal quartz vein type and fault-controlled skarn type.The quartz vein type is mainly controlled by the NE-NNE fault and joint fissures, and the skarn type is mainly controlled by the near-east-west fault fracture zone.

Key words: ore-controlling structure, skarn type, quartz vein type, prospecting indicator, scheelite, western Zhen’an area, South Qinling
