摘要
该类型矿床形成过程，主要可划分为火山喷流沉积和潜火山气液叠加改造两大成矿、蚀变期。从破火山口演化规律入手，分析研究了环形火山构造对矿床形成的制约作用。
The forming processes of such kind of deposits can be primarily divided into two metallogenic and alter-ation epoches.The first is the sediment of volcanic eruption,and the second is the superimpeed refnrm by subvolcanic gasand liquid. Through study of the evolution of caldera,the author expounds the control of annular volcanic structures tothe formation of ore deposit.
