本文对河南卢氏县椿树沟-娘娘庙钼(钨)矿区的围岩蚀变类型及矿石矿物特征进行了研究。研究结果表明,该矿床围岩蚀变主要早期的矽卡岩化形成镁质矽卡岩,后期迭加了热液蚀变作用,交代早期矽卡岩又形成透闪石、阳起石、金云母、蛇纹石、钼(钨)矿物等组成的含水晚期矽卡岩。其中后期迭加了的液蚀变作用与矿化关系最为密切;矿石类型以单钼型矿石和单钨型矿石为主,钼钨型矿石出现在钼、钨矿体叠加部位。矿石中主要金属矿物为辉钼矿、白钨矿、黄铁矿。
In this paper, the rock alteration types and mineralogy characteristics of surrounding rocks in the Chunshugou-Niangniangmiao Molybdenum (Tungsten) mine in Lushi County, Henan Province were studied. The results show that the main early skarn alteration of the deposit formed magnesian skarn, and hydrothermal alteration was superimposed in the later stage of the ore deposit alteration. Early skarn also formed tremolite, Mica, serpentine, molybdenum (tungsten) minerals and other aquifers composed of late skarn. The liquid alteration which is superimposed at the later stage is most closely related to the mineralization. The types of ore are dominated by mono-molybdenum type ore and monotungsten type ore, and the molybdenum-tungsten type ore appears in the superimposed part of molybdenum and tungsten ore body. The main minerals in the ore are molybdenite, scheelite and pyrite.
