... the newly collected geochronological and geochemical data from this study depends on the current understanding of the geologic framework and geologic history of the Beishan region, which is briefly outlined below. The Beishan region exposes east-trending mountain ranges that reach elevations of 2–2.5 km...

... the time of closure of the Palaeo-Asian ocean was in or after the late Permian. The Beishan mountain range is composed of several arc belts that are separated by six ophiolite-bearing melange zones, which are marked today as major faults, shown in Figures 1 and 2 a (Zuo et al . 1990 , 1991 ; Liu...
