Lithospheric Thickness Recovery from Horizontal and Vertical Land Uplift Rates
International audience As a result of the BIFROST studies of the Fennoscandian postglacial rebound, it is known that in addition to uplift, there also exists a horizontal movement of the Earth's surface, so that points on it move away from the uplift centre at a rate of about 10% of that of the...
