摘要
本文系统讨论了黔西南凝灰岩型金矿的层控特征。重点认为该类型金矿明显受地层层位、岩性、岩相、层内构造及其它相关地质构造的控制,尤其是受矿源层———峨眉山玄武岩及其相邻地层岩石的控制,成矿作用也表现出层控矿床所具有的热液蚀变特征和多阶段性。
A systematic discussion of stratabound feature of tuff-type gold deposits, southwest Guizhou is conducted. It is emphatically figured that this sort of gold deposits is apparently dominated by succession of strata, lithology, lithofacies, interbedded tectonic and associated geological structures, especially the source beds of Emeishan basalts and stratigraphic rocks nearby, furthermore the metallogenesis is of the hydrothermal alterations and multi-stage features characterized with stratabound deposits.
