Описание: This book presents a brief synopsis of the current academic understanding of the plume hypothesis, its surface manifestations and its shortcomings. It also describes methods for estimating the uplift history of a region due to plume activity. It discusses different models for the elastic properties of the lithosphere and their estimation as a background for plume emplacement, and introduces the plume hypothesis, describing the major plume types and their effect on the lithosphere. Two chapters are dedicated to the dynamic and permanent topography produced by an impinging plume head below the lithosphere and its estimation. It also presents the historical background of the plume hypothesis, its criticisms and alternatives.

Discovery of the perovskite to post-perovskite phase transition in MgSiO₃, expected to occur for deep mantle conditions, was first announced in April 2004. This immediately stimulated numerous studies in experimental and theoretical mineral physics, seismology, and geodynamics evaluating the implications of a major lower mantle phase change. A resulting revolution in our understanding of the D″ region in the lowermost mantle is well underway. This monograph presents the multidisciplinary advances to date ensuing from interpreting deep mantle seismological structures and dynamical processes in the context of the experimentally and theoretically determined properties of the post-perovskite phase change; the last silicate phase change likely to occur with increasing pressure in lowermost mantle rocks.
