拉伸线理：拉伸线理（stretching lineation）是由拉长的砾石、鲕粒、岩屑、矿物颗粒或矿物集合体等的平行定向排列构成的线状构造。
在片理面上发育有强烈的拉伸线理，这些线理则是由拉长的矿物定向展布而显示。
On the surface of foliation there develops strong stretching lineation defined by alignment of elongated minerals.
熔体线理发育在深部构造层次韧性变形带中，与矿物拉伸线理一样具有运动方向指向意义。
Melt lineation developed in ductile deformation zones of deep structural levels of crust and may indicate the moving direction as the mineral stretching lineation does.
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.
