风成沙丘普遍存在角砾前积、拖曳褶皱和倒转褶皱等同沉积变形构造。

The synsedimentary deformation structures are common in eolian dunes, such as brecciated foresets, drag folds and overturned folds.

在制定油气开发方案前，必须建立一个完整的构造演化、沉积作用、成岩作用的综合模式，进而预测有利构造沉积成岩相带。

So, before a development scheme of oil and gas is formulated, a synthetic model on structural evolution, sedimentation, and diagenesis should be set up to predict the favourable zones.

中生代构造快速沉降的沉积体的楔形展布表明盆地具有前陆岩石圈挠曲成因特征；

The Mesozoic rapid tectonic subsidence and wedge shaped sedimentary bodies indicate the origin of lithospheric flexure in the Chuxiong Basin.
