无产阶级文化大革命以来,在世界著名的钨矿产地-赣南发现了两个新类型矿床:一个是花岗岩浸染型黑钨矿矿床,一个是花岗岩浸染型白钨矿矿床,现介绍如下.花岗岩浸染型黑钨矿矿床:矿床中的钨主要呈黑钨矿浸染于蚀变花岗岩中,因而得名.矿区内出露的地层为寒武系中上部浅变质砂岩夹板岩,该区东部有泥盆系砾岩、砂页岩,石炭系砂页岩、灰岩,以及白垩系红色岩层.矿区内断裂构造发育,以北东向为主,北西、北西西向次之.矿区及其外围燕山期酸性岩浆的侵入和喷发活动十分强烈,形成大片
Since the Great Proletarian Cultural Revolution, two new types of deposits have been discovered in Gannan, a world-famous tungsten ore producing place: one is a granite-disseminated wolframite deposit and the other is a granite-disseminated scheelite deposit, which is described below. Wollastonite Deposits: The tungsten in the deposit is mainly derived from wolframite infiltrated into altered granite, hence the name of the deposit.The strata exposed in the mines are the Cambrian Upper Paleo-metamorphic sandstone plinths and the Devonian basin in the east of the area Department of conglomerate, sand shale, Carboniferous sand shale, limestone, and Cretaceous red rocks.Fault structure developed in the mining area, mainly to the north and east, followed by the north west and north west-west.The acidity Magmatic intrusion and eruption activity is very strong, the formation of large
