Consequences of mantle heterogeneity for melt extraction at mid-ocean ridges

Abstract:

Evidence for chemical heterogeneity of the mantle is found at most mid-ocean ridges, yet we are only beginning to develop a theoretical understanding of how this heterogeneity affects basalt petrogenesis. In particular, the consequences of heterogeneity for magma transport through the mantle are not known. We address this question with computational models of coupled magma/mantle dynamics and thermochemistry beneath ridges. The models are initialised with simple, hypothetical patterns of mant...
