试析贵州省铜元素地球化学图所透露的地质信息

根据贵州省铜元素地球化学图透露的地质信息，结合相关资料对比分析，本文认为：(1)黔西北峨眉山玄武岩覆盖区具有较好的找矿前景；(2)下三叠统曾超覆于黔东南地区的上元古宇、石炭系和二叠系等地层之上，该地区在晚二叠世应存在一片古陆；(3)峨眉地裂运动在石炭纪就开始影响贵州；(4)燕山期构造运动对贵州铜元素的再分配有明显影响(5)从江县南部摩天岭花岗岩体北缘接触带很值得进行深入研究。

Primary Analysis on the Geological Information from the Geochemical Map of Copper Element in Guizhou Province

By the geological information illustrated from the geochemical map of copper element in Guizhou Province, a comparative analysis is made by integrating the relative data. In the opinion of writer, the distributive province of Emeishan basalt in northwestern Guizhou is of fairly prospective; lower Triassic once overlapped the layers of upper Proterozoic, Carboniferous and Permian in Southeastern Guizhou, in which an ancient land of late Permian may come into being; Emeishan fracture movement in impacting on Guizhou originated from Carboniferous; Yanshannian structure movement affects apparently the re-location of copper element; Contact zone at north wing of Motianlin basaltic body in the south of Congjiang is fairly valuable to carry on further research.
