Outline of Final Research Achievements

Until about 10,000 years ago there were multiple large lakes in the Andean plateau region. As a result of climate change these lakes dried up resulting in the formation of salt flats such as the famous Uyuni area. There are numerous shorelines cut into the slopes surrounding the basin. These shorelines are excellent paleo horizontal markers. The elevations of these shorelines were measured using GPS surveying in 27 localities and the ages estimated by dating carbonate sediments associated with the shorelines. The results show that the same group of shorelines locally shows uplift of about 20 m that occurred over about 10,000 yrs. The main uplift is found in the center of the basin suggesting it was caused by a reduction in water level and load on the crust resulting in inflow of weak mid crustal rocks.
