摘要:
天津市蓟县地区，第四系更新统地层较发育，并发现丰富的哺乳动物化石和古人类活动遗迹。作者根据实测剖面由老至新划分为二个组：（１）中更新统小岭子组，为洞穴堆积物，由含角砾砂质粘土，夹石灰华及“灰烬层”组成，可见厚度５．９～６．６ｍ。其中含梅氏犀、肿骨鹿、硕猕猴、李氏野猪等动物化石；（２）上更新统官善村组，为地表沉积物，由砂质粘土，夹透镜状砂和砂砾层组成，厚度＞１６ｍ。该组中产有披毛犀、普氏野马、纳犸象、野猪、纳呼尔锦羊、蒙古兔、欧洲野兔等代表性分子。
Abstract:
In the vicinity of Jixian of Tianjin Municipality, Pleistocene strata are well developed, andabundant manmmal fossils and fossil remains of the human species were discovered. According tothe data of measured sections the strata are divided in ascending order into two formations: （1） theMiddle Pleistocene Xianlingzi Formatin, 5.9-6.6m thick is represented by speleothem composedof angular fragment -bearing sandy clay with tufa and "ash layers", yielding Dzcerohinus cf.Kirchbergensis, Megaloceros Pachvosteus, Macaca robustus, Sus lydekkeri etc.; （2） the UpperPleistocene Guanshancun Formation, more than 16 m thick is marked by surficial deposits, Con-sisting of sandy clay with lenticular sand and gravel layers, yielding Coelodonta antiquitatis, Equ-us przewalskyi, Paleoloxodon naumanni, Sus scrofa, Bbson sp., Ovis nahoor, Lipus tolai, L. eu-ropaeus etc. The mammal fossil assemblages contained in the above-mentioned formations can be correlat-ed with the Middle and Late Pleistocene faunas of Zhoukoudian of Beijing and Salaus of InnerMongolia.
