【摘要】：煤系石墨是煤及煤系碳质页岩等在岩浆热接触变质及构造变质作用下形成的,是石墨矿产的重要组成部分,也是煤系非金属矿产的一种,属于战略性新兴矿产。文章综述了前人对煤系石墨的研究成果及其勘探开发现状,着重讨论了构造作用在煤系石墨形成过程中的作用,并强调煤在石墨化过程中微观结构的演化。本文认为,现阶段对煤系石墨的成矿机制和赋存规律的认识不够深入,缺少针对性的勘查规范和相关标准,同时也将完善石墨成矿机制和赋存规律、建立煤与石墨的鉴别标志、确定煤系石墨资源评价方法、划分成矿带并调查煤系石墨的资源量定为下一步在煤系石墨调查评价中的重点研究方向。
[Abstract]:Coal measure graphite is formed by magmatic thermal contact metamorphism and tectonic metamorphism. It is an important part of graphite mineral and also a kind of nonmetallic mineral of coal measure.This paper summarizes the research achievements of coal measures graphite and its present situation of exploration and development, emphatically discusses the role of tectonism in the formation of coal measures graphite, and emphasizes the evolution of microstructure of coal during graphitization.This paper holds that the present understanding of the metallogenic mechanism and occurrence law of coal measures graphite is not deep enough, and lacks of relevant exploration norms and relevant standards. At the same time, it will also perfect the mechanism and occurrence law of graphite mineralization, and establish the distinguishing mark between coal and graphite.Determining the evaluation method of coal measures graphite resources, dividing into ore belts and investigating the amount of coal measures graphite resources are the next important research directions in the investigation and evaluation of coal measures graphite.
