【摘要】：煤系石墨是煤及煤系碳質(zhì)頁巖等在巖漿熱接觸變質(zhì)及構(gòu)造變質(zhì)作用下形成的,是石墨礦產(chǎn)的重要組成部分,也是煤系非金屬礦產(chǎn)的一種,屬于戰(zhàn)略性新興礦產(chǎn)。文章綜述了前人對煤系石墨的研究成果及其勘探開發(fā)現(xiàn)狀,著重討論了構(gòu)造作用在煤系石墨形成過程中的作用,并強(qiáng)調(diào)煤在石墨化過程中微觀結(jié)構(gòu)的演化。本文認(rèn)為,現(xiàn)階段對煤系石墨的成礦機(jī)制和賦存規(guī)律的認(rèn)識不夠深入,缺少針對性的勘查規(guī)范和相關(guān)標(biāo)準(zhǔn),同時也將完善石墨成礦機(jī)制和賦存規(guī)律、建立煤與石墨的鑒別標(biāo)志、確定煤系石墨資源評價方法、劃分成礦帶并調(diào)查煤系石墨的資源量定為下一步在煤系石墨調(diào)查評價中的重點(diǎn)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.
