摘要
文章重点探讨了断裂构造动力成矿的机制及模式,并以此为基础,全面分析了湖南沃溪金矿含金石英脉中金及SiO_2在断裂构造动力成矿作用下垂向和侧向上的积聚过程,指出断裂构造动力成矿作用与该矿床的形成演化有密切关系。
The structure dynamic mineralization theory is so important in study of geology of ore deposits that more and more geologists have been paying close attention to it, it has provided new enlightenment and opened up new sphere and shown new prospects for the study of geology of ore deposits and structural geology. Fracture structure dynamic mineralizating occupies an important place in this theory. This paper discusses mainly the mechanism and model of the fractural dynamic mineralization. Furthermore, based on this mechanism and model the accumlative process of gold and SiO_2 in vertical and horizontal dimension under the fractural structure dynamic mineralization of Woxi gold deposit in Hunan Province is analysed. It is pointed out that the fractural dynamic mineralization is closely related to the formation and evolution of the ore deposit.
