摘要
本文以秦岭泥盆系中与铅锌矿化有关的铁白云石硅质岩为例,从岩石的产出状态、沉积构造环境、岩石学和岩石地球化学特征等出发,阐述了岩石的喷流沉积成因,同时提出岩石作为喷流岩的识别标志及其可能的找矿线索.
Exemplified by the ankerite-siliceous rocks that related to the Pb-Zn mineralizations in Devonianformations in Qinling Mountains, and proceeded from occurrence mode, sedimentary-structural environment, petrographic and lithologic-geochemical features, this paper expounds the exhalative-sedimentaryorigin of such rocks and suggests that these rocks may be used as a recognition marker of the cxhalites and a possible clue for exploration.
