本文以地洼成矿理论作指导,采用地质历史分析和构造应力分析相结合的方法,研究了辽宁杨家杖子钼矿田中主要矿床的控岩、控矿构造特征。文中在宏观上和微观上用大量的地质事实论证了成矿作用受北东构造系活动控制的机理,并提出了矿田内矿床和矿化点具有等距性分布的规律。同时,还论述了区内钼矿床与地洼激烈期重熔再生岩浆演化晚期的花岗斑岩在时间上,空间上和成因上的密切联系。这些矿床具有多阶段、多来源和多成因的成矿特点。因此,它们应属于地洼型斑岩钼矿系列中不同型式的矿床组合。
In this paper the theory as a guide diwa mineralization, geological history analysis method and the combination of tectonic stress analysis to study the main control Tanaka rock deposit in Liaoning Yangjiazhangzi molybdenum, ore controlling structures. In the paper, macroscopically and microscopically, a large number of geological facts are used to demonstrate the mechanism of the metallogenesis controlled by the activities of the Nidong tectonic activity. The law of equidistant distribution of ore deposits and mineralized sites in the orefield is proposed. At the same time, it is also discussed that the molybdenite deposits in the area are closely related in time, space and genesis with the granitic porphyry of late Pleistocene reclaimed magmatic evolution in Diwa. These deposits have multi-stage, multi-source and multi-genesis of metallogenic features. Therefore, they belong to the different types of deposit assemblages in the Diwa type porphyry molybdenum series.
