Abstract: The thrust nappe structure system in the Beilongjiang area is composed of six basic structural units,i.e. Yaerma-Zhouqu thrust zone, Pohai-Baiyi-Wuping thrust zone, Xiqing mountin-south of Wuping nappe zone,Maqu-Nanping thrust zone,tensional basin in the northern foot of Guanggei mountin and Gahai-Langmusi basin。The thrusting restilts from muItiple subductions of ocean crust of Tethys and Indian plate beneath Sino-Korean plate since Hercinian-Indosinian, which produce the Hercinian-Indosinian folded belt in the margin of continent crust(south Qinling) and southward imbricate thrust nappe structures.It is formed that magmatic zones and gold mineralization zones migrate southwards in time and genetic type, including, in order,Qingkeyan-Yaerma-Zhouqu Indosinian hypabyssal calc-alkali magmatic zone and Yanshanian mid-epithermal fine disseminated As-Au mineralization zone, Pohai-Laerma-Baiyi early Yanshanian calc-alkali stiperhypabyssal subvolcanic and magmatic zone and early Hymalayan mid-epithermal hotwater cryptoexplosion-type fine disseminated gold mineralization zone,Maqu-Nanping latest Yanshanian magmaticzone and mid-late Hymalayan mid-epithermal hydrothermal and hot-spring-type gold mineralization zone.
