THE MESO-NEOPROTEROZOIC TECTONO-STRATIGRAPHIC DIVISION ON THE EPICONTINENTAL MOBILE BELT IN NORTHERN LIAONING PROVINCE
There exists a series of Meso-Neoproterozoic tectonic melanges and o phiolitic melanges in Jianping-Fuxin-Tieling area of northern Liaoning Provinc e. Their original rocks are volcanic rocks,epicontinental clastic sedimentary ro cks, and ophiolite of volcanic and island arc tholeiitic series or calcium alkal i series. The rocks coexist closely, distributing in a narrow and long belt in t he Late Precambrian orogenic belt in northern Liaoning. The rock series could be subdivided into Weijiagou rock group and Kaiyuan rock group (including Shenjiap uzi rock formation, Zhaobeishan rock formation and Banshigou rock formation).
