我国青藏高原的湖泊是世界上海拔最高和面积最大的内陆湖区之一.这些湖泊多为构造湖,它们的形成和发展受着构造因素的控制。在这些湖泊中盐湖占一百多个。盐湖中蕴藏着极其丰富的矿产资源,是我国重要的石盐、芒硝、锶盐、硼酸盐、锂盐和钾盐的产地。本文报道了青藏高原几个盐湖的C~(14)年龄,并对其近三万年来的沉积旋迥进行了剖析,根据上述资料认为该区更新世与全新世的界线划在一万年左右为妥。
The lakes of the Qinghai-Tibet Plateau in China are one of the world’s highest and largest inland lake areas, most of which are tectonic lakes whose formation and development are controlled by structural factors. Salt lake in these lakes accounted for more than a hundred. Salt Lake is rich in mineral resources, is China’s important stone salt, Glauber salt, strontium salt, borate, lithium and potassium salt origin. This paper reports the C ~ (14) ages of several salt lakes on the Qinghai-Tibet Plateau, and analyzes the sedimentary rotation over the past 30,000 years. According to the above data, the boundary between Pleistocene and Holocene in this area is about 10,000 years To be proper.
