| 摘 要： | 乌拉山金矿成矿流体为中－中高 温，中高压力，盐度中等偏低，低密度，弱酸性－弱碱性和还原环境的ＣＯ２－ＮａＣｌ－Ｈ２Ｏ体系。韧－脆性剪切变质变形作用和岩浆活动控制着流体发育过程，成矿作用的演化从早期→晚期，从西段→东段具有规律性变化，大气降水在其演化过程中起了重要作用。

| Abstract: | The metallogenic fluid belongs to the CO 2 NaCl H 2O system which is medium high temperature ,medium high pressure,below medium salinity,low density, slight acid slight alkali and reducing environment.The development of the fluid is controlled by the ductile brittle shear metamorphism deformation and the magmatic activities.The evolution of mineralization is from early to late period and from west to east part, which presents a regular change.Meteoric water plays an important role in evolution. |
