2) continental crust arc 陆壳型弧 1. Each island arc in the Northwest Pacific island arc system is composed ofcontinental crust arcand oceanic crust arc (except for the Mariana island arc). 西北太平洋岛弧系列中的各岛弧(除马里亚纳岛弧为洋壳型弧外)均由陆壳型弧和洋壳型弧组成,并且左端与大陆相连...
Based on these velocity and density models and as a result of subsidence analysis we suggest the presence of continental crust beneath the Levantine Basin. The depth migrated nultichannel sections reveal recently active faults that cut through the entire evaporitic and post-Messinian sediment layer....

density of the refractory residue, but delamination may still have been prevented by the incoming buoyant Indian continental crust67. Instead, the densified lower crust would become part of the seismic sub-arc lithospheric mantle (Fig.5b). This process is evidenced by the presence of ~85 Ma ...
Thin oceanic crust is formed by decompression melting of the upper mantle at mid-ocean ridges, but the origin of the thick and buoyant continental crust is enigmatic. Juvenile continental crust may form from magmas erupted above intra-oceanic subduction
