摘要
在吉林磐石、湖南郴州、湖南新化、福建永安、福建大田、陕西凤县、内蒙古巴音淖尔等地开展典型煤系石墨矿床野外调查采样和分析测试基础上,探讨煤系石墨鉴定指标。XRD(晶格间距d_(002))是鉴定煤系石墨的可靠指标,Raman(R_(2))是鉴定煤系石墨的辅助指标;煤系石墨的鉴定指标:煤系石墨(d_(002)=0.3354~0.338nm,R_(2)≤0.55)、煤系半石墨(d_(002)=0.338~0.344nm,R_(2)≤0.65),当XRD参数与Raman参数不一致时应以XRD参数为准。
Based on field investigation,sampling,analysis and testing of typical graphite in coal measure deposits in Panshi of Jilin,Chenzhou of Hunan,Xinhua of Hunan,Yongan of Fujian,Datian of Fujian,Fengxian of Shaanxi,Bayannur of Inner Mongolia,the identification index of graphite in coal measure is explored.XRD(lattice spacing d_(002))is a reliable index to identify graphite in coal measure,Raman(R_(2))is an auxiliary index to identify graphite in coal measure;the identification indexes of graphite in coal measure are:graphite in coal measure(d_(002)=0.3354~0.338nm,R_(2)≤0.55),semi-graphite in coal measure(d_(002)=0.338~0.344nm,R_(2)≤0.65),when the XRD parameters are inconsistent with the Raman parameters,the XRD parameters should be as the criterion.
