摘要
本文应用PC—1501机对香花岭矿田的节理进行了优势产状求解、定量配套、主应力轴方向计算及方位图的绘制。证实该区自古生代以来的三期构造应力场分别为:南北向、东西向及北西向主压应力作用的结果,它们分属于加里东期、印支期及燕山期构造运动的产物,其压应力在三度空间上呈波状传递,较好地解释了现今宏观构造的格局。并从构造的角度得出北东向节理裂隙是本区最佳容矿构造的认识。
PC--1501 computer is applied to solute the predominant mode of occurrence, make quantitative fitting, calculate the direction of principal axis of stress and plot principal oritations diagram for the joints of Xianghualing ore field. It is proved that the three tectonic stress fields since paleozoic in this area are the results of the NS-trending, EW-trending and NW trending principal compressive stress respecsively. They seperately belong to the product of caledonian, Indo-sinian and Yanshanian tectonic movements.The compresrive stress transmis undulantly in the three-dimensio space, which makes a good interpretation of the nowadays macro-structural pattern. And an understanding is obtained that the NE trending joint fissures are the opiemal ore-containers from the structural point of view.
