摘 要: | <正> 贵德和化隆两盆地跨贵德、尖扎、化隆、湟中、贵南五县,平均海拔高度约2500—3000m,海拔4600m的扎马山将两盆地分隔为二,两盆地内新第三纪陆相地层十分发育,分布广,厚度大。1885年,Loczy,(即Nehring)将盆地内红层命名为“贵德系”或“贵德建造”,记述了化石Myospalax arvicolinus,时代为上新世。Bohlin(1938)、路兆洽(1948),杜恒俭(1948)等分别对盆地内红层提出不同的时代划分意见。解放后,青海地质局、郑绍芬等(1984)先后进行古生物地层工作。本文获国家自然科学基金委员会资助,继

Division and correlation of the Neogene rocks in the Guide and Hualong Basins in Qinghai Province |

Abstract: | The Guide and Hualong Basins are located in the northeastern border of the Qinghai-Tibet plateau. The Neogene red terrestrial deposits of 1330-3700m thick are well-developed in these two basins. Based on palaeontology and lithostratigraphy, the Neogene rocks inthis area are divided ascendingly into five formations; Miocene-Chetougou, Xianshuihe,Charang, Xiadongshan and Pliocene-Shangtan Formations. |
