摘要
西藏区域地质调查大队在1∶100万日喀则幅区调中将措勤地区划分为两个地层小区,各自建立了下白垩统的岩石地层系统。作者根据在该区测制的下白垩统连续地层剖面及相关地质调查,认为这两个地层小区并不存在;建议在措勤地区建立统一的下白垩统岩石地层系统,从下至上划分为则弄组、多尼组和郎山组。
The Coqen area was divided into two stratigraphic subregions by the Xizang Regional Geological Survey Party during the 1∶1000000 region geological survey in the Xigaze Yadong. The different (lithostratgraphic) systems of the lower Cretaceous were set up in each stratigraphic subregion respectively. Based on the geological survey and a perfect section of the Lower Cretaceous found in this area, this paper believes that the two stratigraphic subregions divided by predecessors does not exist in the Coqen area. The lithostratgraphic systems of the Lower Cretaceous should been the same in Coqen. They are ascendingly the Zelong Formation, the Duoni Formation and the Langshan Formation.
