    • Abstract
  • Jinjiahe gold deposit is located in the middle part of Mian-Lue-Kang structural hybrid zone. The gold orebodies occur in the nearly east-west or north-west structural alteration zone, with favorable geological conditions of mineralization. Through the analysis of mine geological characteristics, mineralization alteration belt/orebody characteristics, wall rock alteration and ore mineral characteristics, the authors summed up some controlling factors of the deposit. The mineralization type was tectonic altered rock type controlled integratedly by the ductile shear zone, formation and acidic dike. The main source bed was the volcano-terrigenous clastic sedimentary rock in Nanhua-Sinian period. The mineralization was closely related to some multiphase hydrothermal activities and developed in the tectonic slices of carbonate quartz schist, with pyrite being the main gold-bearing body. The secondary ductile shear zones of F14, F15 and F16 in this area, developed beside the long fault F13, were the ore-conducting structure and the ore-hosting structure as well.
