摘　　要：寒武纪生命大爆发一直是国际研究的热点,作为全球地质事件及地质演化不可缺少的地区之一,鄂尔多斯盆地寒武系基础地质研究尚待深入,其油气勘探也尚待突破。为了进一步丰富该地区的基础地质数据,本次研究精选鄂尔多斯盆地周缘9条中寒武统徐庄组野外剖面,对192个岩石样品进行系统的采样、制片及鉴定。岩石种类齐全,包括陆源碎屑岩、碳酸盐岩、混积岩等。本数据集详细展示了徐庄组岩石薄片的矿物成分及含量,结构构造、生物化石的观察与描述以及成岩作用,并且提供了系统的偏光显微照片。本文可以为全球中寒武世基础地质研究提供数据支撑,同时也为鄂尔多斯盆地中寒武统油气勘探提供基础地质资料参考。The Cambrian explosion has always been a hotspot of academic research worldwide.As a major region where global geological events and geological evolution took place,Ordos Basin has attracted scholarly attention for geological research on the Cambrian system.Yet studies in this respect awaits to be deepened,and especially,breakthrough is to be made for regional oil and gas exploration.To enrich regional geological data,this study selected nine field sections from the Middle Cambrian Xuzhuang Formation in the periphery of the Ordos Basin.A total of 192 rock samples were systematically sampled,sliced,and identified,with a full coverage of the rock types including terrestrial clastic rocks,carbonate rocks,mixed rocks,etc.This dataset is a systematic assemblage of polarized photomicrographs of the rock sections,which records their mineral composition,content,structural formation,and detailed observation and description of the biological fossils and their diagenesis.It can not only be used to support basic Cambrian geological research worldwide,but also provide basic geological data references for oil and gas exploration at the Middle Cambrian strata in the Ordos Basin.
