Geological Features and Ore Prospecting of the Bilugangan Deposit,Abaga,Inner Mongolia

The Bilugangan molybdenum deposit in Abaga,Inner Mongolia,is a medium porphyry deposit found in the Erlian-Dongwuqi metallogenic belt in the recent years.Ore bodies occur mainly in the monzo-granite-phohyry and Permian strata.The geochemical prospecting shows that the ore-forming elements of Ag,Pb,Zn,Cu,Mo and W abnormal shapes very complex,and have many concentration centers,which distributed in north-east direction.The element concentration centers coincide with each other well.Ore body formation is associated with silication,sericition and K-metasomatioin.Metallogenesis is related to the deep faults,magma activities and hydrothermal ore-forming solution.Summarizing the geological and geochemical prospecting characters for this deposit,we put forward its metallogenic regularity,which is an important clue to further prospecting work in the study area.
