地质学

Under the guidance of the theories of sedimentation, paleontology, stratigraphy, reservoir geology and digenesis, synthetically applying the methods of the conjunction of spot-line-surface, macro-microscopic and field-indoor, there is a comprehensive study for the upper Permian series in stratum, rock, sedimentary facies and diagenesis, especial for the type and characteristics of sedimentary facies, in the paper.

本文主要是以沉积学、古生物学、地层学、储层地质学等相关理论为指导，运用点线面、野外与室内、宏观与微观相结合的方法，并借助普通显微镜、阴极发光显微镜等手段对川西地区北部上二叠统的地层、岩石、沉积相以及成岩作用进行了研究，尤其是对沉积相的类型及特征作了详细的划分与阐述。

Though the fossiliferous explosion known as the Cambrian period is often thought of as the beginning of animal life, animals actually appeared for the first time during a geological twilight called the Ediacaran, 635m-542m years ago, between the end of a great ice age and the arrival of all those well-preserved Cambrian fossils.

有不计其数的化石来自于寒武纪，尽管寒武纪被认为是动物最先出现的时期，但实际上，动物出现的最早证明来自于一个地质学上的突破发现，即存在于6.35亿与5.42亿年之间的埃迪卡拉动物群化石的发现，这个时间正位于大冰川期结束，化石大量被保存的寒武纪开始之前。
