摘要
温江寺金矿床赋存于三叠系断陷盆地深水—半深水复理石建造中,该套沉积岩系是矿床形成的物质基础,金矿(化)体严格受具韧-脆性的近东西向(北西西向)断裂构造带和北东向断层破碎带控制,二者交汇部位往往是矿体产出部位,岩脉的侵入主要起着改变岩石力学结构以便含矿热液渗入和萃取金矿化物质的作用。矿区已发现4条矿带,容矿岩石主要为钙质板岩,矿石类型主要为(碳酸盐化)石英脉型。综合矿区地质特征、控矿条件、成矿作用等认识,认为矿区深部及外围化探异常较好,构造发育部位是下一步扩大矿体规模有利地段。
Wenjiangsi gold occurred in deep water - half deep water flysch formation of Triassic depression basin. The set of sedimentary rocks is the material foundation of the mineral deposits formation. The body of gold deposit （mineralization） is strictly controlled by near EW-trending shear fault and NE-trending fault zone, and is often located in convergence of the two faults group. Intrusive veins mainly play the role of changing rock mechanics structure so that the ore-bearing fluid infiltrates and extracts gold mineralization substance. Four ore belts have been found in the dis- trict. The host rocks are mainly calcareous slate. The ores are mainly quartz（ or carbonation） vein type. Based on com- prehensive understanding of geological characteristics, ore-controlling factors and mineralization ,we think that the deep mining and peripheral mining area with good geochemical anomalies and developed structure bear ore-prospecting po- tentials.
