| 摘 要： | 湖相碳酸盐岩在可可西里盆地的古、新近纪地层中分布广泛,更是中新统五道梁群沉积的主要组成部分。五道梁群湖相碳酸盐岩分为生物粘结灰岩(叠层石)、泥晶灰岩、颗粒灰岩与泥晶白云岩四大类,反映出沉积环境为一个具有浅水—半深水、高盐度、半封闭—封闭特点的综合湖泊系统。

| Abstract: | The lacustrine carbonate rocks occur on a wide range of scales in the Palaogene and Neogene strata in the Hoh Xil Basin,Qinghai,and constitute an important part of the Miocene Wudaoliang Group sediments.The lacustrine carbonate rocks in the Wudaoliang Group consist of boundstone(stromatolite),micritic limestone,grainstone and micritic dolostone which were laid down in the shallow-water to bathyal,high-salinity and enclosed to semienclosed lake systems. |
