塔儿沟钨矿经过几年的普查勘探,对本类型的矿化特征及其富集规律进行了初步研究,现整理成文,介绍如后,不当之处,请批评指正。 (一)概况该区石英脉型黑钨矿床,以规模大、矿化深及品位富为特点。矿脉主要赋存于震旦系的绢英片岩、角闪石英片岩中,其所充填的裂隙,是由祁吕山字型构造体系西翼之北东向挤压作用所形成的北西向断裂带而派生的矿化裂隙。矿脉密集成带,有五个矿带(即Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ矿带),按其构造方向可分两组:一组为北西向(Ⅰ、Ⅱ矿
Taruogou tungsten mine after several years of census exploration, the type of mineralization characteristics and enrichment of the law conducted a preliminary study is now collated, introduced, such as inappropriate, please criticism. (A) Overview The quartz vein type wolframite deposit in this area is characterized by its large scale, deep mineralization and rich grade. The veins mainly occur in Sinian schlieren-schist and hornblende schist which fill the northwest fault zone formed by the eastward extrusion of the west wing of the Qilu-Shan structural system Derived mineralization cracks. There are five ore zones (ie, Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ ore zone) which can be divided into two groups according to their tectonic direction: one is northwest direction (Ⅰ, Ⅱ ore
