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。

Based on the analyses of the regional gravity and magnetic anoma-lies, the Lanshan-Lingxian gravity gradient belt may be used to be a boundary of the second unit of the geotectonic elements, the great rift and hidden igneous body possess evident features of regional gravity and magnetic anomalies. Therefore, it is very significant by using regio-nal gravity and magnetic data to study the geological problem and prospecting for ore. The regional gravity and magnetic anomalies suggested in this paper applying to the minerognetic prognoses in Southern Hunan deal with the following five aspects: (1)The regional deep fractures indicated by the gravity data are essential in controlling ore deposition. Metallic ore deposits of conside-rable size are most likely to occur at the intersection of regional fracu-res with surface structures. (2)The magnetization zones indicated by the aeromagne tic data arc found to be ore-controlling. (3)The hidden granite bodies indicated by the negative gravity anomalies can serve as a guidance to the further prospecting for ore deposits at depth. (4)The mineralized, altered and fractured zones indicated by the chain of brachy aeromagnetic anomalies are of significance in disting-uishing ore-controlling fracture zones from the numerous surface fracture zones. (5)Local magnetic anomalies at places of favourable minerogenetic environments are significant for delineating specific ore deposits.

根据对区域重磁异常的分析,蓝山—酃县重力梯度带可作为湘南二级大地构造单元的分界线。在各地质单元中,深大断裂以及隐伏岩体等,都有明显的区域重磁异常特征。因此,利用区域重磁资料研究湘南地质和找矿问题是有意义的。文中提出的区域重磁异常在湘南成矿预测中的应用有如下五个方面: 1.重力资料所反映的区域性深断裂具有重要的控矿作用,尤其是与表生构造的交汇部位最易形成大矿。 2.航磁资料反映的高磁区有明显的控矿作用。 3.重力负异常反映的隐伏岩体,对于开展深部找矿具有指导作用。 4.短轴串珠状航磁异常反映的矿化、蚀变、断裂破碎带,对于从地表众多的断裂构造中区分出具有控矿作用的断裂带是有意义的。 5.在成矿地质环境有利地区的局部磁异常,对于查明具体矿床有重要意义。

The gravity anomaly of 21/2-dimensional combined model is similar to that of 3-dimensional ones. The mathematical expression of gravity anomaly for 21/2-dimensional dipping mass surface derived from that of 21/2-dimensional dipping tabular body is rather simple. In genaral, theshapes of these anomalies are quite close. All their relative errors do not exceed 15%.The iterative inversion approach for defining three-dimensional density boundaries based upon the calculation of gravity anomoly due to 21/2-dimensional dipping mass surface is established. It involves the solution of a linear algebraic equation system with the unknown vectors representing the modified values of boundary depth. By iterative corrections of the boundary depth one can get the satisfactory results.Such kind of calculation is made for an ore-controlling trap and satisfactory result is obtained.

2(1/2)度体组合模型的重力异常与三度体的重力异常非常接近.根据2(1/2)度倾斜板状体的异常表达式导出的2(1/2)度倾斜物质面的重力异常表达式很简单,在一般情况下物质面的异常与板状体的异常是接近的,相对误差不超过15%.引用2(1/2)度倾斜物质面的重力异常计算式建立了三维密度界面迭代反演方法.该方法归结为求解一个以界面深度修改量为未知向量的线性代数方程组,反复对界面深度进行修正,直到获得满意的结果为止.计算了一个控矿构造实例,取得了较为满意的效果.
