摘要
以绿片岩相为主的霍各乞矿区含矿地层内存在一些特殊的热水沉积岩。通过矿物学、岩石学、矿物共生组合以及地球化学特征判断，主要岩石类型包括硅质岩、含电气石岩、重晶石岩、透辉石、透闪石岩以及铁镁碳酸盐岩类等。这些岩石的存在和研究对于本矿床及狼山地区成矿作用和矿床成因的认识有重要启示意义。
There are some special hot water sedimentary rocks associated with the ores among the ore-bearing strata of greenschist factes in the Huogeqi copper-polyrnetallic ore region, Inner Mongolia. Through detailed mineralogical. petrographic. paragentic and geochemical studies, five main types of hot water sedimentary rocks can be recognized: some of silica (protolith of banded quarzite) .tourmaline .baritic.diopside-tremolite and ferromagnsian carbonate rock. The existence of these rocks and more reseach of them will play an important role in understanding ore genesis of the Langshan (the Wolf Mountain)region.
