【摘要】 位于广西田东和田阳县境内的布兵盆地,是百色盆地东南部边缘的一个小型附属盆地。盆地内部及其南部边缘发育11层喀斯特洞穴,洞穴堆积物中保存大量的哺乳动物化石、人类化石以及石制品,其时代包括2 Ma以来的多个时期。盆地内还发育4级河流阶地,第Ⅳ级阶地堆积物中含有旧石器及玻璃陨石。布兵盆地的发育始于白垩纪末、古近纪初喜马拉雅运动阶段,至少自第四纪以来,盆地处于间歇性抬升时期,形成多层洞穴和阶地。这些洞穴和河流堆积物对于研究华南第四纪环境变迁和生物演化等具有重要意义。更多还原

【Abstract】 Bubing basin,located at Tiandong and Tianyang County,is an adjunctive small basin at southeastern Bose basin.Karst caves are broadly developed at the limestone towers inside the basin,and southern marginal limestone Mils.So far,our five years research works in this basin have indicated that about 11 layers caves are at different elevations,varying in sediments and mammalian faunas deposited during several periods from early Pleistocene to Holocene,generally between 2 Ma to 500 a.Some of these caves are rich of Hominoid elements of Hylobates,Gigantopithecus,Pongo,Homo fossils and bone,tektites and stone artifacts.Four fluvial terraces are also distributed at the Bubing basin,the highest one contains stone artifacts and tektites in laterite sediment,which corresponds to the Bose basin stone industry morphologically and stratigraphically. Geological studies reveal the Bubing basin was primitively developed during the end of the Cretaceous period and the earlier Paleogene,and intermittently uplifted since beginning Quaternary at least.Numerous layers of caves and terraces were formed and situated at varying elevations.So,the cave deposits and terrace sediments are significant in study of Quaternary environmental changes and mammalian evolution in south China.更多还原
