| A Study of Characteristics and Modes of Occurrence of Mineralized Fissures in the Jiaojia Gold Deposit |
| Based on an analysis of structures, this paper emphatically studies characteristics of mineralized fissures as well as channels, modes and genetic mechanisms of liquid migration.The authors consider that differential mineralizations mainly result from different fissures, and there is no clear boundary between these microstructures. The mineralized fissures exist in two forms:extension of micro-fissures driven by liquid and extension of vein fissures caused by shear and tension. Liquid migrates mainly by way of vacuum pump. Different genetic mechanisms and migration forms lead to different mineralization characteristics. |
