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.
