Analysis of the Scale Size and Metallogenic Characteristics of Crystalline Graphite Ore
摘要
Abstract
The size of crystalline graphite scales is closely related to the geological background and ore type of mineralization.This article is based on on-site research and comprehensive research.Analyzed the characteristics of graphite scales in different mineralization zones.Research has shown that:Large scale graphite deposits are mainly located in the middle of the northern margin of the North China Craton,Southern part of Jiamusi Xingkai plot,Jiaobei Uplift,South margin of North China Craton-Qinling Mountains,Huanglong fault type graphite mineralization belt.Large scale graphite ore is mainly graphite Gneiss,Schist,granulite,marble type ore.The earlier the formation age(Neoarchean to Proterozoic),the higher the degree of deterioration,the larger the crystal,the metamorphic degree generally reaches hornblende facies to granulite facies.Small and medium-sized scales are mainly distributed in the Yangtze landmass,New Huaxia Ancient Land,North of Jiamusi Xingkai Block,Middle section of the northern margin of the North China landmass,Junggar Block,etc.Small and medium-sized scales were mainly formed from Mesoproterozoic to Cambrian.A small amount was formed in Carboniferous.The ore types are mainly graphite schist and graphite quartz,the metamorphic facies are generally greenschist and amphibolite facies.关键词
