摘要
小秦岭地体中的褶皱包括露头褶皱和宏观褶皱，组成褶皱的面理为次生构造面理。露头褶皱为地壳早期在伸展机制下发生左行张扭剪切作用产生的构造形迹；宏观褶皱为侵入岩浆穹起。
The fold in the Xiaoqinling terrane included the outcrop fold and macrofold, and the foliation formed by the fold was the secondary structural foliation. The outcrop fold was a structural feature formed by the crust occurred the left lateral tenso shear shearing under the extentional mechanism in the early period. The macrofold was a tectonic framework formed by the uplift of invasive magma and by spreading space outward and compressing wallrock of diapirism.
