The strata inside and outside the cave are argillaceous bedded limestone and wormkalks of late Cambrian, that is, 490—500 million years before present.

洞内外地层为距今4.9亿年—5亿年的晚寒武世泥质条带灰岩和竹叶岩状灰岩，它们都是在浅海中生成的，说明当时鱼谷洞地区曾是一片大海。

Thus the mathematic model can predict anisotropy of drillability by using rock drillability in perpendicular direction to the bedding plane of formation.

由垂直于层面方向的声波速度计算出垂直于岩石层面方向的岩石可钻性，从而可以对地层可钻性各向异性及造斜特性进行评价。

Based on the filtration theory, the deliverability test theory and model are discussed and the relationship between coefficient of the binomial deliverability equation and the penetration rate, depth of pay zones and skin factor are analyzed.

从渗流理论出发，阐明了产能试井的原理及模型，分析了二项式产能方程系数与渗透率、地层厚度和表皮系数的关系。

The biostratigraphy of Cretaceous/Tertiary boundary sections from eight localities is summarized and compared in order to define a continuous or complete section.

Works on marine micropaleontology in China started in the late 1950's, and in the last thirty years, the marine micropaleontology in China has been greatly expanded into a full-fledged discipline that includes taxonomy, ecology, sedimentology, biostratigraphy, paleoenvironmental analysis and geologic resources prospecting, and deals with finding and explaining various species buildup, ecologic condition, sedimentary distribution, and their historical processes.

中国的海洋微体古生物学研究开始于20世纪50年代末，当时属于起始摸索阶段。真正发展并奠定基础的时期是在近30年以来，较为全面地开展了分类学、生态学、沉积学，生物地层学、古海洋环境分析与地质资源勘探应用研究等。

Based on the study of biostratigraphy and anoxic eventstratigraphy, we propose that the Qingshankou Formation may correspond to the oceanic anoxic event at the CenomanianTuronian boundary in the Cretaceous, and the age of the Qingshankou Formation in the Songliao Basin is the Late Cenomanian to the Early Turonian.

结合生物地层研究成果，认为青山口阶下部曾发生过古湖泊缺氧事件，其层位大体可与白垩纪古海洋CenomanianTuronian界线事件层进行对比，由此提出了松辽盆地青山口阶下部的时代归属于晚白垩世Cenomanian晚期-Turonian早期的新观点。
