辽宁抚顺地区金成矿系列划分与典型矿床特征研究

辽宁抚顺地区金矿床成矿地质条件优越。为了挖潜金矿找矿潜力,通过收集、分析和研究有关地质矿产资料,结合实际工作和最新勘查成果,对红透山大型铜锌金矿、下大堡中型金矿和下营子中型铜金矿3个典型矿床成矿特征进行了详细论述。根据研究区金矿地质特征、成矿时间、成因类型、地质构造和金异常分布等因素,划分为3个成矿系列组合,4个成矿系列,4个成矿亚系列,确立6个Ⅵ级找矿远景区,认为太古宙与受变质海相火山热液活动有关的块状硫化物型铜锌金矿床和燕山期与中浅成、中酸性侵入岩有关的金银矿床具有较好找矿前景。研究工作为在老矿区外围和已知成矿带指明了找矿重点区和找矿方向。

Division of metallogenic series and the typical characteristics of gold mineralization in Fushun, Liaoning Province

The metallogenic geological conditions of gold deposits is superior in Fushun area, Liaoning Province. In order to tap the potential of gold deposits, by collecting, analyzing and researching relevant geological and mineral resources, combined with actual work and latest exploration results, the paper discussed the detail of metallogenic characteristics of three typical deposits, such as the Hongtoushan large-scale copper-zinc-gold deposit, the Xiadabao medium-scale gold deposit and the Xiayingzi medium-sized copper-gold deposit. According to the geological characteristics, metallogenic time, genetic type geological structure and gold anomaly distribution, the study area is divided into 3 metallogenic series combination, 4 metallogenic series, and 4 metallogenic sub-serie. Also the paper briefly describes the characteristics of each mineralization series, and 6 Ⅵ-grade metallogenic prospect areas were divided. It is believed that the massive sulfide type Cu Zn Au deposits related to metamorphosed marine volcanic hydrothermal activity in Archean and the gold and silver deposits related to the intermediate hypabyssal and intermediate acid intrusive rocks in Yanshanian have good prospecting prospects. The research work points out the key prospecting area and prospecting direction for the periphery of the old mining area and the known metallogenic belt.
