Geological Characteristics and Prospecting Direction Analysis of Songshumao Donggou Lead-zinc Deposit in Huludao,Liaoning Province
The Songshumao Donggou lead-zinc deposit is located at the northeast end of the Bajiazi Yangjiazhangzi magmatic hydrothermal non-ferrous metal mineralization belt.The development of fault structures in the area and the intrusion of early Yanshanian granodiorite provided sufficient thermodynamic conditions and material sources for the mineralization of lead-zinc deposits.The formation of fractured alteration zones and skarnization at the stratigraphic contact sites resulted in the formation of hydrothermal filling and metasomatism type deposits.The fractured alteration zone and silicification are the most direct prospecting indicators in this area.By studying the geological characteristics and mineralization conditions of mineral deposits,suggestions for prospecting directions are proposed.
