| Abstract: |
| By the analysis of Geological characteristics of mineralization of the Zijinshan southeast ore block Cu-Mo deposit ,pointed out that the copper-molybdenum mineralization is mainly hosted by granodiorite porphyry inside and outside the contact zone ,in porphyritic granodiorite porphyry upper, Gold mineralization is hosted in dacite porphyry , breccia of supergene oxidation zone . By the analysis of fabric characteristics of the ore , mineral build order, the mineralization evolution of deposit is divided into three metallogenic periods, respectively, porphyry hydrothermal period, high sulfidation epithermal period and supergene oxidation period. Further the porphyry hydrothermal period is divided into three stages, respectively, biotite- K-feldspar stage, quartz- sericite stage, carbonate stage. The high sulfidation shallow epithermal period is divided into three stages, respectively, dickite petrochemical stage, alum petrochemical stage, silicification stage. To provide a basis for further study of genesis .(修改所有英文部分,保证专业名词和语法结构的准确性) |
