| 中文摘要: |
| 颜家沟金矿矿体产于石英二长斑岩体内部及其与白云岩接触部位的构造蚀变带内.在岩体内部为石英脉型Au、Cu矿化,岩体内接触带则为网脉状蚀变岩型Au、Pb、Zn矿化,岩体外接触带是构造蚀变岩型Ag矿化.主矿化体受石英二长斑岩体及次一级构造和裂隙控制.经过岩桨期后气成热液叠加改造,构成了复杂的成矿过程,初步认为该矿床属岩浆期后多次气热叠加型金多金属矿. |
| 英文摘要: |
| Eight ore bodies have been found in the Yanjiagou gold deposit through comprehensive geological methods including geological survey and drilling. Ore bodies, most of them are blind, occur in the inner part of quartz monzonitic porphyry or at contact structural alteration zones with dolomite. Quartz vein type Au and Cu mineralization occurs in quartz monzonitic porphyry, and stockwork altered rock type Au, Pb and Zn and structural altered rock Ag mineralization individually occur in the inside and outside contacting zones. Main ore bodies are controlled by quartz monzonitic porphyry, subsidiary structures and fissures. Superimposition and reformation by hydrothermal fluids of post - magma made mineralization process complex. |
