对内生矿床来说,当成矿物质具备之后,构造条件是否有利就成了是否成矿的关键性因素,而“构造迭加”则又往往决定着矿床的富矿部位,这种认识早已为地质工作者所接受的,以徐山钨矿床为事例。徐山钨矿床,经工作证明,在垂直方向上是上部为脉状钨矿,中部为矽卡岩型钨矿,下部为花岗岩型钨矿的“三位一体”的多类型钨矿床,规模达到大型钨矿。
For endogenous ore deposits, whether the structural conditions are favorable or not is the key factor for metallogenesis after the ore-forming materials are available, and the “structural superposition” often determines the ore-rich parts of the ore deposits, which is already known For geological workers accepted by Xu Shan tungsten deposit as an example. Xushan tungsten deposit, proved by the work, is a multi-type tungsten deposit of the “Trinity” in the upper part of the vein type tungsten ore in the vertical direction, the skarn type tungsten ore in the middle part and the granite type tungsten ore in the vertical direction, Large-scale tungsten ore.
