B型俯冲与A型俯冲(国外英文资料) B subduction and type A subduction B subduction and type A subduction are two basic types of subduction. A subduction is a process of subduction of one plate to another. These two basic subduction types can be distinguished by the difference between the subduction and the subduction plate properties, mainly of the crust type. B-type subduction The Binioff subduction, the subduction of the oceanic plate beneath the continental plate, can also be a subduction of the great ocean plate to another small ocean plate. [url =] because this kind of subduction is always subducted by benioff [/ url] [D1] And benioff zone and is always accompanied with the side of the trench, trench and subduction of oceanic plate subduction, so this kind of dive with American geologist H.B inioff surname is named for the first letter B. Type B subduction, including the yang-land subduction (the edge of the sea and the sea without the edge) and the ocean subduction. Typical b-type subduction development in east and west on both sides of the Pacific, is also found in the Indian Ocean northeast of Java trench, Puerto Rico trench in the Atlantic and south Thornton Welch trench, as well as the southern Mediterranean Crete Helens trench. The Japanese scholar, also known as the Uyeda (1982), subducted the type B subduction by the arc of the island or the arc of the ocean, further into two types: the Chilean and the mariana type. In Chile subduction type, two plates are connected closely, including arc after the arc groove is in a state of extrusion, back-arc without oceanic crust as the basement of the basin, back-arc earthquake seismogenic is thrust type, benioff zone Angle slow, shallow trench, hyperplasia of subduction complex; In the mariana dive,Is actually out of the two plates, after the arc is tension, back-arc earthquake seismogenic is normal fault type, benioff with steep dip Angle, trench where no subduction complex hyperplasia. The reason for this is that the upper plat
