    西藏那曲地区孔玛盆地第四纪昆虫化石的发现及意义

    Discovery and significance of insects fossil in the Quaternary Kongma basin, Naqu, Tibet, China

    • 摘要: 首次在西藏那曲地区孔玛盆地第四系湖相沉积地层中发现了昆虫化石,对昆虫化石的特征和产出层位进行了描述,昆虫化石经初步鉴定分别属于膜翅目、双翅目和异翅目。采集了该套地层的ESR年代学样品,测试结果表明该套地层的时代为早中更新世。昆虫的分布演化与环境关系密切。这一发现为研究青藏高原第四纪以来的生物进化,湖泊、河流演化,气候变化,古地理、古环境变迁,第四系地层划分等提供了新资料。

       

      Abstract: Recently insects fossil have been discovered in the Quaternary Kongma basin, Naqu, Tibet for the first time. Their basic features and the location are described. Primary identification suggests that the insects fossil belong to diptera,heteroptera and hymenoptera. The test results of ESR geochronology samples belong to Early midio-pleistocene. The discovery have provide new data for the organic evolution, the lake and river evolution, the climate change, the paleogeographic and the paleoenvironment changes, and the stratigraphic division of Quaternary.
