摘要: 本文通过对贵州烂泥微细浸染型金矿床中辉锑矿显微形貌和超微结构观察,发现辉矿晶体中出现显微波纹扭裂纹,沿扭裂纹部位被辰砂充填交代和辉锑矿晶体中存在大量变形双晶、层错、位错壁、亚晶粒等变形超微结构,从而为成矿过程中锑、汞矿化之间这段区间发生构造应力作用了微观的成因信息。

Abstract: Based on the examination of super microstructure and micromorphology in stibnite from Lannigou micro-disseminated gold deposits of Guizhou province, the wavy microfissure in stibnite crystal, which are filled by cinnabar, are observed and some deformation super microstructure, such as deformation twin, stacking fault, free dislocation, dislocation wall and subgrain are revealed. All these super microstructures provide genetic information on microscale for the tectonic processes developed between the stages of Sb and Hg mineralizations.
