雩山结合带及其非史密斯化过程

Yu shan combination and non-smith process

中国东南华夏板块的武夷山地块与罗霄地块之间存在一个非史密斯的地层带 ,称为雩山结合带。它是早古生代华夏板块与扬子板块拼贴过程中形成造山带的一个部分 ,自早奥陶世开始消减—中晚奥陶世主期挤压—中志留世伸展—晚志留世走滑四个阶段的非史密斯化过程。

There is a non\|smith tectonic zone between Wuyi block and Luoxiao block in Huaxia plate of Southeastern China,this zone is called Yushan Combination Zone.It is a part of orogenic belt which be formed by collision of Huaxia plate and Yaugtze plate in Early Palaeozoic.This non\|smith process can be divided into four stages:(1) starting subduction from Early Ordovician period;(2)major press stage during Middle\|Late Ordovician period;(3)extension stage during Middle Silurian period and (4) trend slip stage during Late Silurian period.\;
