subduction

1.(3)controls on the updip and downdip limits of the seismogenic zone of subduction thrusts;

③在俯冲逆冲断层上，发震上界和下界的确定；

2.After that, rapid cooling retrograde metam orphism occurred.Early rapid ocean spreading was constrained because subduction appeared.Therefore, metagabbro continued to uplift under the slow extension.

因俯冲作用的开始，抑制了洋盆快速扩张，变质辉长岩在速伸展环境下继续抬升压；
