摘要
江西省广昌县万山红地区长石矿赋存于震旦系片岩裂隙带中,主要控矿构造为裂隙,矿区出露地层简单,主要有震旦系洪山组和第四系地层,矿区内构造呈单斜构造,总体北东向,倾向南东。矿区内主要发育4条长石矿脉(M1~M4),矿石结构以花岗结构为主,块状构造。万山红长石矿床成矿物质来源主要为燕山中期花岗岩体,为后期长石脉侵入抑或含钾热液沿断裂裂隙交代而成,总体上属于岩浆岩型矿床类型。
Occurring in schist fracture zone of the Sinian System,the ore-controlling structure of Wangshanhong feldspar deposit in Guangchang County of Jiangxi Province belongs to fracture,whose exposed strata is simple and inner structure is monoclinic,with four feldspar lodes in massive granite structure.The ore-forming material source of Wangshanhong feldspar deposit is granite body from Yanshanian Middle period,invaded by feldspar vein or dissolved by potassium-bearing hydrothermal fluids along the fractures,belonging to magmatic deposits.
