tectonic erosion

Material shows that the tectonic erosion periods occurred six times since 1.6 Ma. B.P. The depth eroded by each tectonic erosion period was different, it varies generality between 5 and 130 m.

资料表明，黄土高原约160万年以来发生了6次构造侵蚀期，各次侵蚀期下切深度存在差别，深度变化一般在5～130m之间。

The deformation of the landslide is mainly caused by new tectonic movement, earthquake, fracture zone and influence from soft stratum, and as well as by rainfall, river erosion and human activities.

滑坡变形主要受新构造运动、地震活动、断裂破碎带、软弱地层影响，同时受降水、江水冲淘和人类活动作用。

The Late Yanshanian uplift and the cooling of the plutons were caused by early tectonic denudation and late weathering erosion, which led to the good deposition response in basins.

燕山晚期岩体隆升和降温由早期构造剥蚀和晚期风化剥蚀造成，并具有良好的盆地沉积响应。

Based on the principles of physical chemistry, a formula is established for quantitatively calculating formation fluid pressure after tectonic uplifting and erosion in a closed system.

根据物理化学原理，建立了完全封闭条件下构造抬升剥蚀后地层流体压力的定量计算公式。

The tectonic erosion period is different from those occurred in sea and lake basins, and the erosion produced by the former happened mainly in river valleys, hill areas and the edge slope of table lands.

黄土高原构造侵蚀期与海、湖盆地构造侵蚀期不同，它所造成的侵蚀主要限于沟谷、丘陵区和塬边。

According to the material of field investigation and survey, tectonic erosion periods and their erosion are studied.

根据野外调查和实际测量资料，研究了黄土高原构造侵蚀期和期内造成的侵蚀。
