Terrestrial palynostratigraphy of the Upper Cretaceous (Santonian) to lowermost Paleocene of southern Alberta, Canada

A large amount of palynological research has been undertaken on the Late Cretaceous–Paleocene strata of the plains area of southern Alberta. The present study is a summary of the palynoflora encountered in individual rock units across the region. Previous palynological research has been summarized and a brief summary of the geology of the region provided. A large number of taxa have been identified with many not as yet described. Important palynomorph taxa are illustrated along with a tabulation of all the species identified to date for each stratigraphic unit. A biostratigraphic scheme is proposed with 19 biozones described. Not all of these biozones are present in Alberta and information has been taken from materials in Saskatchewan, Canada, and Montana, United States.

针对加拿大阿尔伯塔省南部平原地区的晚白垩世-古新世地层，已有大量孢粉学研究开展。本研究对该区域各岩石地层单元中发现的孢粉植物群（palynoflora）进行了系统性总结。研究梳理整合了既往相关孢粉学研究成果，并对该区域的地质概况作出简要概述。目前已识别出大量分类群（taxa），其中多数尚未正式发表描述。研究对重要的孢粉型（palynomorph）分类群进行了配图说明，并制表汇总了各地层单元迄今已识别的全部物种。本研究提出一套生物地层学方案，共描述19个生物带（biozones）。需说明的是，阿尔伯塔省境内并非所有上述生物带均有分布，相关资料参考自加拿大萨斯喀彻温省与美国蒙大拿州的相关材料。
