Abstract
The investigation of the actions of aqueous heavy metal salts on mineral surfaces was extended to mercuric sulfate-galena system. Fresh cleavage face of galena was soaked in acidic aqueous mercuric sulfate of low concentrations for 30 min. at room temperatures. The reaction products revealed by electron diffraction were: metacinnabarite (cubic HgS) in random and definite orientation with respect to the substrate, and cinnabar (hexagonal HgS) in a certain epitaxial orientation. Besides, the pattern due to a roughened state of galena cleavage face was observed.
