Study on the Geological Characteristics,Ore-controlling Factors and Genesis Model of the Yaoying Graphite Deposit in Ji'an City,Jilin Province
摘要
Abstract
The Yaoying graphite deposit in Ji'an City,Jilin Province,is located in the third member of the Huangchagou Group(Pt1h3)of the Ji'an Rock Series.It is generally distributed in a pseudo-layered and lens-shaped pattern.The ore bodies are controlled by a syncline structure,with symmetrical distribution on both wings near the core.The deposit is of medium size,and the natural type of ore is graphite amphibole granulite,with good ore quality.The genesis type is a regional metamorphic deposit.Stratigraphic control is the core ore-controlling factor in the study area,and regional metamorphism is the main ore-controlling factor.Fold structures have influenced the distribution pattern of the ore body.The Paleoproterozoic plagioclase granite(γοPt1)has strengthened the migmatization in the study area.Through a systematic analysis of the geological characteristics,geological background,genesis and ore-controlling factors of the Yaoying graphite deposit,a genesis model of the deposit has been constructed.The research results provide theoretical support for the exploration of crystalline graphite in this area.关键词
