Plumes and Their Influence on the Formation of Noble Metal Mineralization in Carbonaceous Rocks

摘要

Increasingly more data on the role of mantle plume in various geological processes have begun to appear in the geological literature. The study of the influence of plumes on the formation and localization of ore deposits is also of keen interest. Before discussing specific examples, let us recall briefly the meaning of a plume and its derivatives. As follows from numerous publications of Russian and foreign scientists, the term plume commonly implies giant batches of outer liquid core of the Earth that reach the Earth's surface . The currently discussed models of origination and evolution of plumes are diverse and remain hypothetical to a great extent. The outlines of plumes at the surface are often uncertain.
