| 中文摘要: |
| 赋金闪长岩类侵入体主要发育于褶皱带中，形成时代在晋宁期至印支期，金矿主要以石英硫化物型主于岩体硫碎带中，成矿时期在印支期到喜山期之间，成岩成矿之间存在巨大时关茂矿物质主要来自岩体及含金沉积岩系，成矿流体以大握降水及建造水为主。闪长岩类侵入体中的金矿床主要是改造作用形成的。 |
| 英文摘要: |
| The gold-hosting diorite was formed in Jinning period to Indosinian and occurs in fold system. The gold mineralization occurs mainly as quartz-sulphide veins; the ore deposits were formed in Indosinian to Yanshanian. There is a great time gap between the age of gold deposits and that of gold-hosting intrusions. Based on the geochemistry of Pb, H and O isotopes, it is considered that the ore-forming materials derived from intrusions and fluid from meteoritic water and formational water. Those types of gold deposits were formed by reworking process. |
