查询词典 accretionary

The Prydz Belt occurs in the Prydz Bay and Denman Glacier, and is located in the interior of a previously proclaimed unified East Gondwana. The absence of subduction-related rocks, such as ophiolite suite, arc accretionary complex and high-pressure blueschist and eclogite, resulted in the argument that the Prydz Belt represents whether a collisional zone or an intraplate reworking belt.

普里兹造山带主要出露于普里兹湾和登曼冰川，因其位于从前假设的统一东冈瓦纳陆块的内部，加之缺少蛇绿混杂岩、岛弧增生杂岩和高压变质岩等与大洋板块俯冲作用密切相关的岩石，所以当前存在着碰撞造山成因和板内改造成因两种不同的认识。

This paper briefly introduces the basic fact of the existence of the PaleoTethys Ocean in the Lungmu Co-Shuanghu suture, i.e. the ages and natures of Early Paleozoic ophiolites, Permian ophiolites, Devonian-Permian radiolarian cherts, accretionary slabs of different natures, two types of tectonic mrlange zones and covers of ophiolites. The starting time of the Paleo-Tethys Ocean in Qiangtang may be traced back to Early Paleozoic and the records about the oceanic basin evolution persisted from the Late Devonian to Late Triassic.
