【摘要】 泥河湾盆地以富含哺乳动物化石和古人类遗址而引起了古人类学家和地质学家的广泛关注,泥河湾层是该盆地中发育的一套晚新生代河湖相沉积物.磁性地层学研究结果表明泥河湾层的形成始于高斯正极性世,经历了松山反向极性世,结束于布容正极性世.本文回顾了针对泥河湾层的磁性地层学研究工作,选取了小长梁、东谷坨、郝家台、洞沟、红崖、虎头梁及许家窑等七个剖面作详细介绍,并进行了横向对比.更多还原

【Abstract】 The Nihewan Basin has attracted much attention of paleoanthropologists and geologists because it is an archeological locality with well-developed late Cenozoic fluvial-lacustrine deposits being rich in mammalian fossils. Magnetostratigraphic results indicate the accumulation of the Nihewan Formation began in the Gauss normal chron and terminated in the Brunhes normal chron, thus record the entire Matuyama reverse chron. This paper review the magnetostratigraphic studies on the Nihewan Formation. Magnetostratigraphic correlation is also made among seven typical sections in the basin.更多还原
