Modulation of mantle plumes and heat flow at the core mantle boundary by plate-scale flow: results from laboratory experiments
We report results from analog laboratory experiments, in which a large-scale flow is imposed upon natural convection from a hot boundary layer at the base of a large tank of corn syrup. The experiments show that the subdivision of the convective flow into four regions provides a reasonable conceptual framework for interpreting the effects of large-scale flow on plumes. Region I includes the are...
متن کاملHeat - Flow Heat - Flow Heat - Flow
Choosing between multiple ontological perspectives is crucial for reasoning about the physical world. Choosing the wrong perspective can make a reasoning task impossible. This paper introduces a Lagrangian plug flow ontology (PF) for reasoning about thermodynamic fluid flow. We show that this ontology captures continuously changing behaviors of flowing fluids not represented in currently implem...
متن کاملMantle flow, melting, and dehydration of the Iceland mantle plume
Recent studies have shown that the extraction of water from the mantle due to partial melting beneath mid-ocean ridges may increase the viscosity of the residuum by 2–3 orders of magnitude. We examine this rheological effect on mantle flow and melting of a ridge-centered mantle plume using three-dimensional numerical models. Results indicate that the viscosity increase associated with dehydrati...
متن کاملOn ‘steady-state’ heat flow and the rheology of oceanic mantle
[1] A constraint on the rheology of oceanic mantle is derived on the basis of a recently established scaling law for the onset of convection with temperature-dependent viscosity. Our approach is free from the assumption of statistically steady-state convection, which has commonly been employed in previous studies. The estimated range of asthenospheric viscosity is 1–4 10 Pa s if the activation ...
متن کاملMantle flow in subduction systems: The subslab flow field and implications for mantle dynamics
[1] The character of the mantle flow field in subduction zones remains poorly understood, despite its importance for our understanding of subduction dynamics. In particular, little attention has been paid to mantle flow beneath subducting slabs. In order to identify processes that make first-order contributions to the global pattern of subslab mantle flow, we have compiled shear wave splitting ...
