摘要
方铅矿、闪锌矿及黄铁矿的特征微量元素含量与其之间的关系表明:该铅锌银矿床与岩浆(火山)热液矿床特征相似,而有别于同生沉积或沉积改造矿床。根据矿床次火山岩脉与成矿关系密切的特征,认为该矿床属中温次火山热液矿床。
Some characteristic trace element contents and diagrams among characteristic trace elements in galena and sphalerite and pyrite show the Caijiaying Pb-Zn-Ag deposit is similar to the ore deposits associated with magmatism (or volcanism) and different from the sedimentary (or sedimentary-reformed) deposits. The ore-forming is closely connected with the subvolcanism. It is indicated that the deposit is considered as a mid-temperature subvolcanic hydrothermal ore deposit.
