摘要
ＨＲ８８－１孔是北京平原区北部继顺５孔之后，又一重要的第四系钻孔。本文描述了该钻孔的岩心特征，运用生物地层学、气候地层学、年代地层学以及岩石地层学等综合分析的方法，对ＨＲ８８－１孔岩心的地层时代进行了研究与划分。并结合地表区域资料，初步建立了本区第四纪地层层序。
HRS88-1, borehole is another Quaternary borehole drilled after Shun-5 bore hole in the north of the Beijing Plain. This paper deals with the core features of this borehole and on the basis of multidisciplinary analysis of biostratigraphy, cli matostratigraphy, chronostratigraphy and lithostratigraphy the geological ages of HR88-1, borehole are studied and divided. The Quaternary stratigraphic sequences are also established for the first time by combining with surficial regional information.
