The Comparative Study on Small Intrusion Type Molybdenum Deposits of Shapinggou and Jinduicheng
-
Abstract
Shapinggou and Jinduicheng are superlarge small intrusion type deposits which located on the East Qinling-Dabie molybdenum metallogenic belt.Comparative study which on the geological features,mineralogenetic epoch,material source,Mineralization dynamics background and small intrusion metallogenic mechanism etc.show some results as following: Two deposits have similarity in many respects such as metallogenic type,Chemical composition of ore-bearing porphyry body,alteration distribution,time consistency of diagenetic and mineralization etc.The mineralization of two deposits is controlled by the small porphyry.The high grade and large reserves molybdenum mineralization in Shapinggou molybdenum deposit are attributed to the blasting breccia,a longer period of time of the hydrothermal activity and the emplacement space of porphyry.The two deposits have a similar metallogenic mechanism of small intrusion mineralization.The Yanshanian deep-hypabyssal granitoids which are homologous with the small ore-bearing intrusion occurred differentiation and evolution in deep.A large amount of hydrotherm and mineral substance that from the granitoids emplaced to the head (or the shallow) of the porphyry or the outside contact zone. -
