摘    要：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。

Abstract: Taking the diwa theory as guidance, the auther studies the structuralcharacteristics of rock-controlling and ore-controlling of main deposits inYangjiazhangzi porphyry molybdenum ore field, Liaoning, by using the methodin which the geological history analysis and structural stress analysis arecombined. In the article a lot of geological materials in macrocosm andmicrocosm can prove the mechanism that mineralization is controlled bystructural actions. The regularity that the deposits and areas of mineraliza-tion possess equidistant arrangment is also pointed out. The close relation intime, space and genesis, between the molybdenum deposits and granite-porphyrywhich formed from remelted and palingenetic magma at later stage of evolutionin diwa intence period is discussed. The deposits possess the features of multi-stages, multi-sources and multi-geneses. Therefore, they are various depositsets which belong to the series of porphyry molybdenum deposits of diwa type.
