A Global Isostatic Load Model and its Application to Determine the Lithospheric Density Structure of Hotspot Swells

  • Chapter
Oceanic Hotspots

Abstract

The concept of “continental drift” advocated by A. Wegener from about 1912 until his death in 1930 was based on geological observations and (for those times) modern principles of isostasy. His idea about the “wandering continents” was complemented and strengthened later on by important notions, among which were the rejuvenation of the oceanic lithosphere and its absorption in the inner Earth after subduction that later evolved as the theory of “plate tectonics” and gained general acceptance in the 1970S. Plate tectonics introduced the radically new notion in geodynamics of the large horizontal motion of about 100 km thick lithospheric plates that were gliding on their substratum, the asthenosphere. The dynamics of the plates, thought to be driven by convection currents in the asthenosphere, determines the relief of the Earth’s crust.
