摘　　要：河南省鲁山县石板河石墨矿产资源丰富。通过地质填图、槽探、钻探等地质工作,发现石墨矿带6条,圈出36个石墨矿体,长度100~1350m,厚1.02~22.19m,平均品位2.50%~5.70%,估算资源量达中型矿床规模,矿床成因类型为沉积变质矿床。通过成矿规律综合研究,认为含碳原岩建造控矿作用明显,区域变质作用和混合岩化作用为成矿提供了温度、压力、变质热液等必要条件,研究成果可为今后在该区开展石墨矿找矿工作提供理论支撑。Lushan county,Henan province has abundant graphite mineral resources in Shibanhe.Through geological mapping,trenching,drilling and other geological work,it was found that there are 6 graphite ore zones in the deposit,36 graphite ore bodies are enclosed,with a length of 100~150m,a thickness of 1.02~22.19m,an average grade of 2.50%~5.70%,and an estimated resource size of medium-sized deposit.The genetic type of the deposit is sedimentary metamorphic deposit.Through comprehensive research on mineralization laws,it is believed that carbon bearing protoliths have a significant controlling effect on mineralization,and regional metamorphism and mixed lithification provide necessary conditions such as temperature,pressure,and metamorphic hydrothermal fluids for mineralization.The research results can provide theoretical support for future exploration of graphite deposits in this area.
