Four main formations of loop bedding in Jiyang sub-basin were upper layers fall down in the process of earthquake, tautening distortion due to earthquake, the frication of earthquake-related surface of fault and the effect of redox and diffuse other formations of loop bedding comprise the effect of earthquake wave, the effect coming from circumrotate of globosity rotation, snowball function, cementation intermittent, the effect of biology, and so on.

综合分析认为震动塌落、震动拉伸变形、地震断裂面的摩擦作用、氧化还原反应和扩散作用是环状层理的主要成因，前三种成因的环状层理往往与其他震成构造伴生，可作为震积岩的良好标志。环状层理的其他成因还包括：地震波传播方式的影响、地球自转产生的涡旋的影响、"滚雪球"效应、间歇胶结作用以及生物成因等。

All kinds of sands and source rock could develop two kinds of accumulation models of graben and horst, forming lots of blind strtigraphic traps.

各种类型的砂体沉积和烃源岩以及盖层可以在空间上形成半地堑和地堑两种成藏模式，发育众多的隐蔽岩性地层油气藏。

Volcanic rocks, characterized by huge phenocryst, multi-phenocryst, clastic phenocryst and corrosive phenocryst, developed with surging rhyolitic, plastic agglomerate and pseudo accumulation structure, showing intrusive contact with big phenocryst granite batholith and granite porphyry vein, demonstrates its plutonic attribution.

According to the characters of organic maceral, organic type, biomarker,it can be divided to five types of sedimentary facies: unrest restricted sea graptolite facies, alluvial restricted sea, carbonate mesa algal deposit facies, mud mesa algal deposit facies and deep water shelf algal deposit facies.

根据烃源岩有机显微组分、有机质类型、生物标志物及成烃能力等特征划分出五类沉积有机相，即动荡局限海笔石相、滞流局限海笔石相、碳酸盐台地藻积相、泥质台地藻积相和深水陆棚藻积相。

Over millennia, rain and ice carved the rock into a landscape of spires and canyons.

在十万年之间，雨水和寒冰雕刻著岩石，将其转变成一个有尖岩、有峡谷的地形。

Buildings in Jaipur were originally painted pink to give the impression of having been built from red sandstone.
