一前言富家坞斑岩铜(钼)矿床,是德兴铜矿的勘探基地之一。在该矿区补充勘探过程中,我们与探勘队协作,共同开展了岩石蚀变与矿化的研究,提出了以下几点看法。 1.矿区含矿岩体的岩浆冷凝作用,可分为四个发展阶段;第一岩浆结晶阶段→第二岩浆结晶阶段→气化岩浆气成水热(自变质)交代作用阶段→岩浆期后热液阶段。 2.蚀变岩石类型主要为:钾长石—(黑云母化)蚀变岩;伊利石—水白云母化蚀变岩,石英—绢云母—水白云母化蚀变岩;绿
I. Introduction The Fujiatang porphyry copper (molybdenum) deposit is one of the exploration bases of Dexing Copper Mine. During the process of complementary exploration in this mining area, we collaborate with the exploration team to carry out research on rock alteration and mineralization and put forward the following views. 1. Magma condensation in the ore-bearing rock mass can be divided into four stages: the first stage of magma crystallization → the second stage of magma crystallization → the hydrothermal (self-metamorphic) metasomatic stage of magmatic gas → the stage of magmatism Hydrothermal phase. 2. The types of alteration rocks are mainly: feldspar- (biotitization) alteration rock; illite-water muscovite alteration rock, quartz-sericite-water muscovite alteration rock; green
