A magma accretion model of oceanic lithosphere is proposed and its implications for understanding its thermal field examined. The new model (designated Variable Basal Accretion—VBA) assumes existence of lateral variations in magma accretion rates a

In this work we consider model formulations that allow better understandings of the relations between Darcy velocity and temperatures in coupled two-dimensional systems. The revised theoretical formulations are capable of accounting for the effects o

We present a novel approach for joint inversion of heat flow, elevation and geoid anomalies which allows simultaneous determination of the deep thermal field as well as crustal and lithospheric structures. The technique is based on computationally st
