摘要
A-560 m-long core, namely core K-1, collected from the Lake Koucha, a closed to semi-closed lake in the southeastern part of the Tibetan Plateau, was carefully studied. The authors analyzed the mineralogy and carbonate composition of the core samples since 30 ka B.P., dated by the age model established upon 5 14C AMS data. The results show that the content of Mg in the calcite can be used as a potential lake salinity proxy in such a closed to semi-closed lake.
