Adjoint inversion of the thermal structure of Southeastern Australia

An efficient inversion framework that gives improved estimates of the thermal state of the crust in Victoria using heat flow measurements and Curie depth in a joint inversion using 3D geological models, and numerical models of thermal diffusion. The outcome of this work is an estimation of the basal heat flux, thermal properties and the heat production rates for the various domains in the model together with uncertainty information.

Invert geology

A method to relate the spatial configuration of mesh nodes to lithology that is differentiable - an adjoint to the inversion of geological structure.

Analytical conduction adjoint

An adjoint to the analytical steady-state heat equation
