| 摘 要： | 独路石墨矿位于泰山一沂山断隆泰山凸起东端，矿床赋存于新太古代泰山岩群雁翎关组之中。矿床内发育6个石墨矿体，呈层状、似层状产出。矿石类型主要为含石墨黑云变粒岩型，石墨矿石属鳞片状晶质石墨矿，石墨矿物片径细小。矿石样品固定碳含量一般为6％～8％，在省内属较高品位。原岩为富含有机质的杂砂岩——沉积凝灰岩，经中低压变质相系变质作用形成石墨矿，属沉积变质成因。找矿标志明显，外围及深部找矿前景良好。独路石墨矿的发现填补了鲁西地区石墨矿空白。

| Abstract: | Dulu graphite mine locates in east part of Taishan--Yishan uplift. Deposit occurs in Yanlingguan formation of Archean Taishan group. Six graphite ore bodies developed in this deposit with layered and lstratiform--like types. Main types of ores are graphite--bearing biotite leptynite. Graphite ores belong to crystalline flake graphite deposit with small diameter. Fixed carbon contents of Ore samples are generally 6%-8%. It is a higher grade in Shandong province. Original rock is greywaeke rich in organic matter, that is sedimentary tuff. Through low--pressure metamorphic facies series metamorphism, graphite deposit has been formed. Its origin is sedimentary metamorphism with obvious prospecting symbol. Exploration prospect is good in its external and deep parts. The discovery of Dulu graphite deposit has filled the blank of graphite deposit in Luxi area. |
