Regularities of Spatial Distribution of Mantle Hot Spots of the Modern Earth

摘要

The mantle hot spots of the modern Earth were first found by P. Morgan and G. Wilson as projections of the deep-earth material flows at the modern Earth's surface, uplifting under the moving lithosphertc plates [1,2]. Since that time, the study of interplate oceanic and continental magmatism and geodynamics associated with the mantle hot spots has advanced the development of this hypothesis. It has led to development of the patterns of their deep structure [3] on the one side, and, actually, negation of their deep structure, on the other side [4]. The most prominent achievement of modern geophysics and geology is the development of visual images of the mantle plumes on the basis of global and local seismic tomography. A recent review of such works is presented in [5]. The given work is devoted to discussion of a poorly studied problem, the estimation of regularities of the spatial distribution of the hot spots in the Earth and their connection with modern and ancient geodynamic processes.
