A dataset of microscopic image of rock slices of Xuzhuang Formation in Ordos Basin

A total of 192 rock samples were collected from 9 field profiles of Xuzhuang formation in the Ordos Basin. The rock types are complete, including terrigenous clastic rock, carbonate rock and migmatite. This data set shows in detail the mineral composition and content, structure, observation and description of biological fossils and diagenesis of thin sections of Xuzhuang formation, and provides systematic polarized micrographs. It can not only provide data support for global middle Cambrian basic geological research, but also provide basic geological data reference for oil and gas exploration of Middle Cambrian strata in Ordos Basin.

本次研究从鄂尔多斯盆地徐庄组的9条野外剖面中共采集192件岩石样品。该数据集的岩石类型齐全，涵盖陆源碎屑岩、碳酸盐岩及混合岩。本数据集详细记录了徐庄组薄片的矿物组成与含量、结构特征、生物化石观测描述以及成岩作用情况，并提供了系统的偏光显微照片。该数据集不仅可为全球中寒武统基础地质研究提供数据支撑，同时也可为鄂尔多斯盆地中寒武统地层的油气勘探提供基础地质数据参考。
