该带中央为揉流褶皱带，往两侧至边缘依次出现鞘褶皱、a型褶皱、b型褶皱。

The mid-belt form flowage fold, from the mid-belt to margin belt, the structural types are successively sheath fold; A-fold; B-fold.

这些褶皱的特征表明它们属于a型褶皱，而a型褶皱通常发育在韧性剪切带中。

These folds are characteristic of a-type fold which are commonly found in ductile shear zones.

强烈的片理、拉伸线理、a型褶皱、鞘褶皱以及糜棱岩，这些构造特征仅仅反映出宏观的证据。

Strong foliation, stretching lineation, a-type folds, sheath folds and mylonite, these structural characteristics only reflect macroscopic evidence.
