Abstract

Through analyzing the gold deposit metallogenic background,deposit characteristics,metallogenic mark and ore-controlling factors of gold metallogenic belt in Nanjin Mountain-Langwa Mountain,it suggests that the gold mineralization in the metallogenic belt concentrated in the middle and late Hercynian period with obvi-ous regional metallogenic characteristics,and the gold deposit is mostly developed inside and outside the contact zone of Saozishan Formation and Baishan Formation volcanic rock in Carboniferous System and Hercynian inter-mediate-acid intrusive bodies(quartz diorite,granodiorite).The gold deposit is controlled by ore-bearing forma-tion,magmatism and structure.According to the metallogenic and distribution features,deposit prediction types are classified and regional metallogenic model is established.
