摘要
呷村矿床是一个特大型的含金、稀土富银多金属矿床.成矿地质特征与日本黑矿相似.矿床形成于中低温、较低压的环境.成矿溶液为中等盐度、低密度水热体系.铅等成矿元素主要来自岛弧火山岩,硫和锶来自深部岩浆和海水,成矿水介质以大气降水为主,为典型海底火山热液—喷气沉积成因的块状硫化物矿床.
The Gacun ore deposit is a auriferous and REE-bearing, silver-rich, polymetallic ore deposit on a super scale. The geological characteristics of the deposit are simllar to those of the Kuroko deposits. The deposit developed in the environment of middle-low temperture and lower pressure. The metallogenic solution was a middle salt and low density system. The Ore-forming elements mainly came from the volcanic rocks of island arc. The sulphur and strontium came from deep magma and seawater. The metallogenic water was mainly meteoric water. The deposit is a typical submarine volcanic hydrothermal-exhalative sedimentary massive sulphide ore deposit.
