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.

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。

This paper describes a new nickel-molybdenum ore deposit, characteristics of mineral composition and ore dressing methods. The deposit is newiy discovered in carbouaceous shale in fossil strata of the Sinian and the Cambrian systesm. Through ore dressing tests at Dahu mine in cili, Hunan, it's found that sieving, jigging and heavy-mcdium separation can all bc used as roughing for rejecting waste. However, the flowsheet with sieving as the principal and jigging as the supplementary means is more rcasonable. The nickel mineral occurs mostly as -10 mm sulphide ore nodule. Jigging is the main method for obtaining high grade nickel concentrate. Part of nickel mineral associated with kappa-pyrite can be effectively floatcd with straw cellulose and xanthatc after carbon removing and molybdenum flotation. The molybdenum mineral size is Icss than 1μm. Except parts occurring in sulphide ore nodule, most of molybdenum minerals are associated with carbonolite, iron, silica and aluminium elements. They are mainly recovered by flotation. With the strong depression of water glass, collophane flotation with rough sulfated soap has yielded good results. This article also gives a brief introduction to the smelting technology of this type of nickel-molybdenum concentrate.

Based on the petrology and the lithochemical statistical data from forty porphyry molybdenum deposits (prospects)and more than ten porphyry copper deposits,the“Ore-forming”intrusions of the porphyry molybdenum in the terrain of“North-China Platform”are tentatively divided into two systems:the granite and the granodiorite. On the grounds of the information about the distribution feature and the geotectonic situation of the intrusions,the goelogical time-range (Ar-Pz) and the thickness(over 40 KM) of the total...

Based on the petrology and the lithochemical statistical data from forty porphyry molybdenum deposits (prospects)and more than ten porphyry copper deposits,the“Ore-forming”intrusions of the porphyry molybdenum in the terrain of“North-China Platform”are tentatively divided into two systems:the granite and the granodiorite. On the grounds of the information about the distribution feature and the geotectonic situation of the intrusions,the goelogical time-range (Ar-Pz) and the thickness(over 40 KM) of the total surrounding strata disturbed by the intrusions,the Mo-content of the acidic intrusive bodies,the goechemieal behavaiour of the molybdenum itself as well as the available data of isotopes and rare-earth elements,this paper presents a discussion on several problems:the tectonic environment,the intruding-emplacing mode and the hydrothermal alteration of the intrusions,the possible types of Ore-mineralization and the regime of the ore-deposits induced by the intrusions,and the source materials of molybdenum ores as well. As a conclusion,this paper has pointed out that the ore-forming intrusions discussed should be the granite series of the mantle-crust (transitional) type

本文在对附近40个斑岩钼矿床(矿点)及+数个斑岩铜矿床岩石学和岩石化学统计计算的基础上,将“华北地台”钼矿床“成矿”侵入体分为花岗岩——流纹岩系列和花岗闪长岩系列。据“华北地台”斑岩钼矿侵入体的分布特征,产出的大地构造部位,围君时限(Ar—Pz)及厚度(>40KM),酸性岩的钼含量,钼本身的地球化学性质及同位素和稀土资料,对“华北地台”斑岩钼矿“成矿”侵入体的侵入构造环境,上侵方式,热液蚀变,有关的矿化类型和矿床构型以及钼的物质来源进行了探讨。指出“华北地台”钼矿斑岩体应属幔壳混合(过渡)型花岗岩系列。
