The ore deposit occurs at the exocontact zone of Yanshanian granite,controlled by a NW-trending interlayer-gliding structural shatter zone.Ore-bearing hydrothermal solutions filled along the structural shatter zone,forming large-scale and well-continued composite orebodies,with silver,tin,lead and zine all reaching the reserves of large deposits. The ore-forming process exhibits polygenetic,multiphase and polystage features.Silver mainly occurs as silver minerals which are sulfosalt minerals of silver-antimony, silver-copper-antimony, and silver-lead-antimony. Silver minerals are extremely fine-grained and exist mostly in the mosaic form, associated especially closely with galena. Through ore microscopic and systematic energy spectral srudies with the help of individual mineral analysis, the authors have preliminarily found out the distribution, enrichment, interrelationship and physical properties of these silver minerals.
