| 摘 要： | 作者通过对锡矿山具有成生联系的褶皱、断层、各种小构造及其控矿特征的研究,确定了本区在晚印支～早燕山期,曾经受北西～南东向的近水平挤压作用,形成了我国巨大的锑矿田。文中运用数值模拟法,计算了成矿期构造应力场平面和剖面主应力矢量和剪应力值,解释了成矿期发育的各类构造及其控矿机理。

| Abstract: | The folds, faults and minorstructures which are connected in formation are devolped in Xikuangshan. According to the studies of the structures and ore deposits, the structure deformation and the mechanism of ore-control are known. The spaces of migration and store in which contained the ore-forming fluids are formed as horizontal compressive stress action on this district with northwest-southeast direction during the stage from Late Indo-China to Early Yanshan. In this paper the author applied the method of numerical simulation to calculate the main stress vector and shear stress in plane and profile on tectonic stress field during the period of mineralizing. It is explained well the structure characteristics and the mechanism of ore-control during the mineralizing period. |
