金山金矿田发现发展过程及其找矿前景

金山矿田的发现与发展经历了古采遗迹调查→石英脉评价→含金层间硅化破碎带追索找矿→含金糜棱岩带评价勘探四个阶段，是地质认识不断深化的找矿实践过程。随着对矿床成因的认识从变质热液石英脉型→斑岩铜矿＂卫星＂型→沉积变质改造层控型→韧性剪切带型的逐步深化，矿田构造的查明突破了＂层控＂和＂一层矿＂的认识，找矿思路朝＂多层矿＂方向转变。金矿构造成矿定位模式的建立打开了区域找矿思路。

EXPLORATION HISTORY AND POTENTIAL PROSPECT OF THE JINSHAN GOLD FIELD

Exploration history of the Jinshan gold ore field has experienced four stages which are making reconnelssance onanclentuneling ired, prospecting for quartz veins,surveying gold-- bearing siliciffed interlayer fracture zones and exploring for gold--bearing mylonite--zone. That is a process of deepening geological idea. As the recognition of the deposit genesis changed frommetamorphosed hydrotherrnal quartz vein type to "planet" type of porphyry copper, to sedimentery metamorphosed reformedstratabound type, to ductile shear zone type, exploring thought changed from "stratabound"and "one ore layer" to "multilayerore". The model of structure mlneralization deposition extends regional exploring thought.
