中国东北兴蒙—吉黑造山带贝加尔运动、萨拉伊尔运动、兴凯运动及泛非运动等之比较

Comparison of Baikalian orogeny,Salair orogeny,Xingkai orogeny,and Pan-African orogeny of XingmengJihei orogenesis zone in the Northeast China

近一个世纪以来,中国东北兴蒙—吉黑造山带及毗邻地域发生在前寒武纪末期或寒武纪的一场造山运动,一直为国内外地质学家所关注。先后提出过:贝加尔运动、萨拉伊尔运动、兴凯运动、泛非运动等来描述或界定这场伟大的造山作用。本文综合区域已有实际资料:区域性角度不整合-磨拉石建造出现的时限,造山花岗岩的测年数据,变质热事件的记录,构造活动残留的遗迹等,界定该期构造运动相对最符合贝加尔运动或兴凯运动创建之原意。而创建兴凯运动的典型区,其时限的可确定性和认知度尤佳,故建议在这诸多用语中,精选"兴凯运动"一语为最宜。

Nearly a century,an orogenic movement has been concerned by domestic and foreign geologists,which occurred in the late Precambrian or Cambrian of Xingmeng-Jihei orogenesis zone and adjacent area in the Northeast China.Baikalian orogeny,Salair orogeny,Xingkai orogeny,and Pan-African orogeny,they have been put forward to describe or define the great orogeny.In this paper,synthesized regional existing data：occurring time limit of regional angular unconformity-molasse formation,measured data of orogenic granite,record of metamorphic thermal event,remaining traces of tectonic activity,defined the tectogenesis accords with the create meaning of Baikalian orogeny or Xingkai orogeny.Typical area of creating Xingkai orogeny,whose time limit has preferred confirmability and awareness.The most appropriate is Xingkai orogeny in these phrases.
