吉林复兴屯金矿床地质特征

Geological characteristics of fuxigntun gold deposit in Jilin

复兴屯金矿床位于吉南—辽东成矿带白山—老岭成矿亚带上,区域"S"型断裂带为金矿的重要控矿容矿构造,矿体赋存于老岭群珍珠门组大理岩、大理岩与大栗子组片岩接触带附近,产出形态主要受北东向、北西向断层及闪长岩脉产状控制。在总结复兴屯金矿床地质条件、地质特征、成矿规律及找矿标志的基础上,进一步指出了区域上和矿区内的找矿方向。

FUxingtun gold deposit is located in south of Jilin-Liaodong mineralization belt. Regional ＂S＂-type fault is a major gold ore-controlling structure. Ore bodies occur in the marble of the pearl gate sery in Laoling group or near the contact zone between marble and Dalizi Group＇s schist. The output shapes are mainly affected by the north- eastern, north- western faults and diorite. On the basis of summarizing the Fuxintun gold deposit geological conditions, characteristics, mineralization and prospecting indications, this paper furtherly points out the mining prospecting direction in regional and the ore district.
