摘要
矿区已查明6条矿化带,圈定银矿体29条。矿体成似层状、透镜状、囊状。银的赋存状态:一是呈类质同象或次显微矿物包体存在于载体矿物中,二是以吸附态或银的次显微包体存在于铅锰矿及铁、锰氧化矿物中。属于具有层控特征的变质中低温热液型银铅锌碳酸盐型矿床。
6 metallogenetic zones have been discovered and 29 Ag orebodies outlined in the orefield. The orebodies are atratoid, lenticular or sack - like. As to the existence of Ag： 1. it exists in the bearing mineral as an isomorph or a submicroscopic mineral inclusion; 2. it exists in the wackenrodite and Fe, Mn oxide as an adherent or a Ag submicroscopic inclusion. This multimetallic deposit belongs to the metamorphic middle - low T hydrothermal Ag - Pb - Zn deposit of carbonate type with the stratabound characteristics.
