tectonic phase

The discovery of this tectonic phase has an important significance in geological sciences.

该早期构造幕的发现，在地学上具有重要意义。

After that, the study area is likely to be gone through three major tectonic phase before the formation of such disharmonic folds: the initial rapid extrusion, the deformation of the mid-back and low-speed extrusion late.

经推测，研究区很可能是经过了三次主要的构造期才形成这种不协调褶皱：初期的快速挤压、中期的变形回复以及后期的低速挤压。

The volcanic rocks formed in a tectonic environment of deep thermal collapse eruption in the Early-Mid Permian late-orogenic phase.

构造环境为早中二叠世造山后期深部热力塌陷火山喷发环境。

The main factors leading to the development of paleokarst in the region were found to be multi-phase tectonic cycle, complicated fault-block tilting and long-term dissolution by chemically active fluids.

根据区域构造演化史提出岩溶演化模式，指出多期的构造旋回，复杂的断块掀斜作用和长期的化学活动性流体的溶蚀是研究区古岩溶发育的主要因素。

The second order tectonic sequence is thought to be the cause of making the variations of stratum sequence resulted from the secondary tectogenesis during certain tectonic phase.

二级构造层序揭示了大的构造幕中次一级构造作用（如构造沉降）所引起的充填地层层序变化序列。
