某矿是赣南现有钨矿中一个典型的细脈带矿床.矿区内主要是前泥盆纪变质岩系.侵入体为呈墙状的花崗斑岩,走向东西,倾向南,倾角50-70°,与矿脈走向大体一致,唯倾向相反(图1).本区的主要褶皱构造为一短轴背斜,矿区即位于背斜的西翼.区内断裂构造可分成矿前、成矿后及成矿同时的三类.成矿前断裂系统走向北东东,接近东西,倾角陡,倾向时南时北(以后者为主),长1300公尺以上,深度最少500公尺.成矿同时的断裂
A mine is a typical vein belt in the existing tungsten deposits in southern Jiangxi Province, where the former Devonian metamorphic series are mainly intrusive granite porphyry, (Fig. 1) .The main fold in this area is a short-axis anticline, and the mining area is located in the west wing of the anticline, and the fault structure in the area can be divided into the ore front, After mineralization and metallogenesis at the same time, the three types of pre-metallogenic fault systems go to the east and northeast, close to east-west, with steep dipping angle and south to north (the latter is dominant) with a length of 1300 meters and a depth of at least 500 meters Simultaneous fracture of mineralization
