拗陷

而早白垩世在NE-SW向拉伸应力场作用下，额尔古纳地块东部形成拗陷带，火山基底构造为NE-NNE向。

But under the control of NE-SW tensile stress field of Early Cretaceous , in the eastern part of Ergun Block sag belt was formed and the basement tectonics is NE-NNE direction .

按照盆地的形态特征和成因特点分成单断、地堑、拗陷三种类型。

According to morphological and genetic features , the basins can be divided into three types : single fault , fault trough and sag .
