| Research Abstract |
Models that try to account for the overall morphology and the growth of the Tibetan Plateau commonly assume the presence of a low viscosity layer in the mid crust. To test this model, GPS measurements were made around Lake Nam Co to determine the heights of lake shorelines. In combination with the results of 14C dating, we show that the water level in L. Nam Co has fallen 20 m in the past 10,000 years. If the proposed low viscosity layer does in deed exist, there should be a corresponding uplift of the shorelines as the water level decreases. However, such uplift was not recognized implying that the distribution and presence of any low viscosity layer beneath Tibet needs to be reexamined.
