摘要
Based on the comprehensive analysis of geology,mineralization features and associated hydrothermal alteration,trace elements,halogen element features of Chajianling orefield M28-Shangwangjia mineralization belt copper-silver polymetallic mine.Thought the mine belongs to epithermal deposit,which has relation of space and genesis with the Yanshanian intermediate-acidity supergene magma rock.It belongs to the "multi-position in one" mineralization that from hydrothermal vein type of Shangwangjia mineralization zone to Skarn type of the M28 anomaly distribution area.
