| 摘 要： | 通过对山西义兴寨金矿床成矿构造动力学条件的分析和研究，得出了以下认识：矿床的成矿作用可被划分为脆性破裂和脆 韧性张开两个阶段。其中断裂的脆性构造动力学条件在成矿作用早期控制成矿体系内的成矿反应快速进行，沉淀出体系物质；断裂的脆 韧性构造动力学条件在成矿作用的中晚期控制成矿反应缓慢进行，分异沉淀出体系物质。在这两种构造动力学环境中形成元素金的两种赋存状态即包体金（晶隙金）和裂隙金

| Abstract: | On the basis of the study on ore forming dynamic conditions of Yixingzhai gold deposit, the authors discuss dynamic conditions of ore controlling structures. Ore forming process can be divided into two stages: brittle fracturing stage and brittle ductile tensing stage. But two stages created characteristically different conditions for hydrothermal ore forming reaction and occurrence form of the gold. At former stage the reaction of the system of ore forming is quick and large quantities of ore forming materials were deposited, while at later stage the deposition of ore forming materials was slow. On these two conditions, the gold has two different occurrence forms: crystal interface and fractionation gold. |
