    Abstract: Plate tectonics can drift continents and push up mountains, but what drives the plates? This is an insider’s account of how we answered questions posed over two centuries ago, and completed geology’s quest for a driving mechanism. Forging through confusing evidence, apparent contradictions and raging debates we arrived at not one but two mechanisms: sinking plates and rising plumes.

    Notes: Coupled thermal histories of the mantle and core are computed under various assumptions about the way the core is cooled, using empirical constraints on the present amounts of heat being transported by various modes of mantle flow. The mantle is cooled mainly by the large-scale flow associated with plates, assumed here to have operated throughout Earth history. The core is cooled by removal of heat from the thermal boundary at the base of the mantle. Plumes (both tails and heads) will accomplish much of this removal, if they originate at the core-mantle boundary, while there may also be a significant effect from the plate-scale flow. Removal by non-plume upwelling from the lower boundary layer cannot be ruled out. The thermal history of the core and the relative importance of plumes depend strongly on whether the heat removal is controlled by the viscosity at the core-mantle boundary (as would be the case with plumes) or by the viscosity within the bulk of the mantle (as would be the case for plate-scale flow or non-plume flow).If plumes are the dominant means of core cooling, the core will not have cooled by more than about 300°C during Earth history. Plumes would have been established early and their heat flux would have been fairly constant. On the other hand, if non-plume upwelling or the plate-scale flow are significant at present, they and plumes could have been much more important in the past and the core could have cooled by up to 1000°C.

    Notes: Surface observables have been calculated for a numerical convection model that includes a dynamic plate; that is, a stiff but mobile section of the upper boundary layer that is driven entirely by internal buoyancy forces. The results for heat flux and topography are virtually identical to those obtained from a partially kinematic model in which plate mobility results from an imposed horizontal velocity on the top surface. These results confirm the validity of the partially kinematic approach, which has been used previously. The partially kinematic approach is more efficient, computationally.

    Notes: [Auszug] WHEN the kinematic theory of plate tectonics was developed over a decade ago, two kinds of questions were posed. The first kind concerned the implications of moving plates of lithosphere for geological processes and for the interpretation of the geological record. The second kind of question ...

    Notes: [Auszug] Schubert and Spohn9'10 assumed that the lower mantle viscosity is the same as that of the upper mantle. This is compatible with postglacial rebound observations11, but the resolution of the observations in the lower mantle is not great, and variations by a factor of 10 or more are possible. ...

    Notes: Abstract Several deficiencies are demonstrated in previous formulations of three-body interatomic forces, and revised and extended formulations are presented for the case of the NaCl lattice. A commonly used formulation of non-central forces and a formulation of the effect of ellipsoidal atom deformation are incorrect. Atom deformation should in general introduce two degrees of freedom in the NaCl lattice, but the only previous correct formulation of deformation effects, the commonly used “breathing shell model,” includes only one degree of freedom. The “shell model” of polarizable atoms has been correctly formulated, but applications seem to have been arbitrarily restricted to the case where short-range forces act only on shells, and not on cores. Because of these errors and incompletenesses, it is concluded that no three-body forces have been convincingly established or characterized, although the necessity of their inclusion in models is clear.
