一、前言我国南岭钨矿,在世界上素负盛名,已有五十多年的开采和研究历史,但具体研究成矿温度的工作至今还很少。本文拟就主要成矿区钨矿成矿温度及有关问题作一初步探讨。关于热液矿床成矿温度的划分,一般认为:500—300℃为高温热液;300—200℃为中温;200—50℃属低温。在实际工作中,鉴定成矿温度的标志常常是依据矿物的共生组合,其次是近矿的围岩蚀变类型及矿脉矿石结构构造等等。目前,利用矿物母液包裹体测
I. Introduction Nanling tungsten mine in our country is well-known in the world and has more than 50 years of mining and research history. However, the work of studying the ore-forming temperature is still rare. This article intends to make a preliminary discussion on the metallogenic temperature and its related issues in the main metallogenic area. On the classification of hydrothermal ore deposit temperature, generally considered: 500-300 ℃ for the high temperature hydrothermal; 300-200 ℃ for the temperature; 200-50 ℃ is low temperature. In practical work, the identification of metallogenic temperature is often based on the symbiotic assemblage of minerals, followed by the alteration type of surrounding rock and structure of ore vein ore and so on. At present, the use of mineral liquid inclusions measured
