1995年7月笔者在青藏高原西北部甜水海湖东南面约100m处(35°21′N,79°35′E,海拔高度4840m)进行钻探和地表剖面采样.经分析在钻孔和地表的湖相沉积中都发现有孔虫化石.在世界上海拔最高、距海遥远的青藏高原腹地第四纪湖相沉积中发现晚第四纪有孔虫化石尚属首次,这为青藏高原环境演化的研究提供了极有意义的新证据
In July 1995, the author conducted drilling and surface section sampling about 100m (35 ° 21’N, 79 ° 35’E, altitude 4840m) southeast of the sweet water lake in the northwestern part of the Qinghai-Tibet Plateau. Foraminifera fossils are found in lacustrine deposits.First Quaternary foraminifera was found in the Quaternary lacustrine sediments of the highest altitude in the world and far away from the sea, which is the first time that the environment evolution of the Qinghai-Tibet Plateau Research provides new and very interesting evidence
