| Abstract: | 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. |
