闽西北与裂谷有关的金银多金属矿床成矿特征

Mineralization Characteristics of Gold-silver-polymetal Deposits Related to the Rift Structure in Northwestern Fujian

本文在简述崇安─长汀古地堑盆地基本特征的基础上，重点论述了与该地堑盆地相关的金银多金属矿床成矿作用特征，建立了裂谷改造－再造型和裂谷沉积变质－热液叠加改造型两种矿床成因类型，阐明了成矿的机制，建立了成矿模式．

Based on clasifying basic characters of Chong an-Changting paleorift valley basin,this paper expounds mineralization characters of gold-silver-polymetal deposits related to the rift valley basin. New deposit genesis types-rifting reform-repeated formation type and refting sedimentary metamorphic-htdrothermal reform type are established.This paper also clarifies the ore-forming mechanism and establishes ore-forming models.
