| 摘 要： | 本文利用传统构造地质学中小构造要素统计方法,从空间上恢复并确定了芒场锡-多金属矿田内印支早期北北西向芒场复背斜和燕山晚期北北东向褶皱;利用趋势面分析方法给出了两期褶皱的叠加部位及其控矿模型。根据叠加褶皱具等距性控矿特点,笔者预测了已知矿床外围的两个未知矿点,经野外验证和工程揭露表明,上述矿点均见有锑、银矿化。

| Abstract: | In this paper,the authors recovered and determined the NW-SE-trending Indosin- ian Mangchang anticline and the NE-SW-trending Yanshanian folds on the Mangchang tin- polymetailic ore field by using a traditional method of structural statistical analysis in structu- ral geology,At the same time,the superposed parts of the anticlines and their ore-controlling model were given by trend surface analysis in space.According to the characteristics of the equidistance of superposed folds,the authors predicted two unknown ore points on the peri- phery of the ore field,which were comfirmed by the field examination and drilling to be the Sb and Ag mineralized. |
