阐明了柴西第三系构造演化以中新统(12Ma)为界,可划分为走滑拉分盆地(左旋)与压扭坳陷盆地(右旋)两个主要阶段。
It is suggested that Miocene ( 12Ma ) can be defined as a borderline to mark off the two stages of Tertiary structural evolution , one is sliding and separate basin ( left-revolving ) and the other is compressive and twisty depression basin ( right-revolving ) .
