浠水—梅川地区金矿成矿条件及富集规律
ORE-FORMING CONDITIONS AND ENRICHMENT LAW OF THE GOLD DEPOSITS IN XISHUI-MEICHUAN AREA
【摘要】 浠水—梅川地区金矿主要形成于燕山晚期,剪切带与岩浆岩是两个重要的控矿因素。金矿化经历了金活化、金初始富集和金成矿三个阶段,并分别与韧性、韧脆性、脆性剪切变形相对应。文中最后提出了该地区金矿成矿模式及找矿有利地段。
【Abstract】 Shear zone and magmatite are two significant ore control elements for the gold deposits formed mainly in Late-Yanshanian in Xishui-Meichuan area. The gold-mineralization can be divided into three stages that are gold activation stage, gold initial enrichment stage and gold metallogenic stage which are respectively related to the ductile, ductile-brittle and brittle shear strains. Finally, the metallogenic model and favorable prospecting places of the gold deposits in this area are advanced in this paper.
