西藏中部,大致在唐古拉山与冈底斯山之间的藏北湖区,发育了一个长条形的海相白垩系沉积区。东起纳木错,经奇林错、昂拉仁错,向西到达革吉县、狮泉河一带(图1)。 本区的白垩系最早经李璞(1955)研究,将门德洛子(多巴区)地区的地层分为四层。王文彬(1957)进一步划分为:下部门德洛子岩系和上部渠生堡岩系。 1968年,吴兆龙等提出门德洛子岩系应在渠生堡岩系之上的看法。笔者同意这一看
In central Tibet, roughly a long strip of marine Cretaceous sedimentary zone has developed in the northern Tibet area between the Tanggula and Gangdise Mountains. East Namco fault, the Kilinate wrong, Angra Jen wrong, west to reach Geji County, Shiquanhe area (Figure 1). The earliest Cretaceous in this area was studied by Li Pu (1955) and the strata in Mendulizu (Dopa area) were divided into four layers. Wang Wenbin (1957) is further divided into: the lower part of the Deluozi rock system and the upper Quang Sangbao rock series. In 1968, Wu Zhaolong et al. Proposed that the Medelozhizi rock series should be above the Quanshengbao rock series. I agree with this view
