Abstract

Large gas-liquid inclusions are found in the galena crystals from some hydrothermal lead-zinc deposits. Inclusions' vacuoles are negative crystals. Their habit, macro- and micromorphology and arrangement are studied. Inclusions have a primary character. It is assumed that gas bubbles formed in heterogeneous boiling solutions have played an important role in their formation. The galena surface over the outermost inclusions is plastically deformed, and specific depressions, or infrequently bulges, are formed. The causes and conditions of the deformation are discussed. Similar positive plastic deformation is reproduced experimentally. The liquid released by opening the inclusions evaporates rapidly depositing NaCl and KCl in an epitaxic orientation on the fresh galena cleavage surface.
