| 摘 要： | 辽宁四道沟金矿床内直接控制矿化的主要为一系列不规则的小型微型裂隙,这些控矿裂隙形成于叠加褶曲作用晚期,是一种脉动构造。叠加褶曲轴都是脉动构造发育的良好地段。根据流体包裹体特征,可将脉动作用划分为四个阶段,表明了成矿的多阶段性。

| Abstract: | In Sidaogou gold deposit, structures directly controlling the mineralization mainly are irregular minor or micro-fissure system. The fissures controlling mineralization formed in the late stage of the superposed fold, and are a kind of pulsation structure. In the axis of superposed fold, the pulsation structure (micro-fissures) developed better than in the limb. The authors also discuss the physical-chemical conditions in the pulsation stage according to the characteristics of the fluid inclusions. |
