摘要
金雨石墨矿是近期新发现的石墨矿床,其位于会理县城南西金雨乡境内,产于古元古界河口群大营山组中段变质岩中,目前在区内共圈定3工业个矿体,矿石为晶质鳞片状石墨。矿床成因为区域变质与热接触变质双重因素作用下形成的沉积变质(改造)型石墨矿床。大营山组中段三亚段下部石墨石英片岩可作为区内的直接找矿标志。
Jinyu graphite deposit is recently discovered in Jinyu Township,in southwest Huili county.The ore is located in metamorphic rock of Middle Member of Dayingshan formation of Proterozoic Hekou group.Now 3 industrial ore bodies are located.The ore is composed of scaly graphite.Genetically it is a regional metamorphism-heat metasomatism-caused（reworked）sedimentary graphite deposit.Quartzgraphite schist at lower part of the third sub-member of the middle member of Dayingshan formation is the prospecting mark for such deposit in the area.
