Mantle Flow and Determining Position of LAB Assuming Isostasy

Isostasy and its Meaning

The theory of isostasy supposes that, in regions which have not been disturbed recently, each vertical column of the earth's crust with a certain minimum radius and extending to a depth of about IOO km has approximately the same mass. To find the deviation from this approximation in a given region, the density must be assumed as a function of depth. Such assumptions used at present for calculat...

Mantle 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...

Explaining the disciplinary capabilities of curriculum and determining its position in the classification of academic disciplines

Abstract: In this paper, effort has been made to investigate the capabilities of curriculum as an academic discipline (CAD) and the question to be answered was whether curriculum could be seen as an academic discipline? This question has been answered in two parts. In the first part, the criteria of scientific disciplines were presented from the perspective of experts and after extracting the a...

Isostasy, flexure, and dynamic topography

Article history: Received 12 January 2016 Received in revised form 26 May 2016 Accepted 27 May 2016 Available online 31 May 2016 A fundamental scientific question is, what controls the Earth's topography? Although the theoretical principles of isostasy, flexure, and dynamic topography arewidely discussed, the parameters needed to apply these principles are frequently not available. Isostatic fa...
