一、问题的提出多年来,众多的地质工作者从各种不同的侧面对大厂矿田锡多金属矿成矿规律进行了多学科研究.基本结论是:成矿物质来源于龙箱盖黑云母花岗岩体,矿化富集主要受岩体及构造控制,地层仅提供了有利岩性条件.近年来也有一些地质学家认为成矿物质是多来源的,成矿是多阶段的,但仍认为矿田中的锡、钨、铜等成矿元素是来自龙箱盖花岗岩体.
First, the problem raised Over the years, many geological workers from various aspects of the Dachang ore tin polymetallic mineralization law carried out a multi-disciplinary research.The basic conclusion is: the ore-forming material from the dragon capped mica The granite body and mineralization enrichment are mainly controlled by the rock mass and structure, and the strata provide only favorable lithology conditions. In recent years, some geologists also believe that the ore-forming materials are multi-sourced and the ore-forming is multi-stage, Ore in the tin, tungsten, copper and other metallogenic elements from the Longbox granite body.
