metagabbro

1.This is the first report on the ophiolite suite, which consists of metasediment, meta-basalt, metadiabase, metagabbro, metapyroxene and metasilicith, in the Wenjiashi area, northeastern Hunan.

在文家市首次识别出蛇绿岩套残片,它由变沉积岩、变玄武岩、变辉绿岩、变辉长岩、变辉石岩及变硅质岩组。

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，变质辉长岩在减速伸展环境下继续抬升减压；
