| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. Quartz-graphite 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. |
