安徽省池州六峰山地区矿床地质特征及成矿规律初探

Discussion on Geological Charateristics of Deposit and Metallogenic Regularity of Liufeng Mountain in Anhui Province

六峰山地区铜矿位于池州市贵池区境内,属长江中下游铁铜成矿带,通过对该地区铁铜硫等矿产控矿地质条件、矿体地质特征、岩石地球化学等研究,证实本区矿产主要受泥盆与二叠系栖霞组之间的断裂破碎带和层间裂隙带控制,结合矿石物质成分分析及结构、构造特征,说明本区矿床主要属中—低温热液型矿床,矿质主要来源于本区的铜质基底和六峰山岩体。进而提出了本区构造裂隙找矿的新方向。

Copper mine of Liufeng mountain is located in Guichi area of Guizhou city, which is belong to Middle - Lower Yangtze Cu-Fe multi-metal metallogenic belt. Through the analysis of mineral ore - controlling geological conditions, geo- logical characteristics of orebody and rock geochemistry about iron, copper and sulfide mineral of this area, the paper con- firmed minerals are mainly controlled by interlayer fissure of Devonian to Qixia in Permian and fracture zone. Combined with ore material composition and structure, it is inferred that this deposit is hydrothermal medium to low temperature type copper mine. Mineral comes from copper basement of this area and rock of Liufeng mountain. Finally the authors put for- ward new suggestion to look for this tectonic fissure copper mine of this area.
