About The Event
Our study makes use of magnetic anomalies produced between the top of crystalline basement and Curie
point isotherm depths, which we call The Magnetic Layer (TML). We study the Permian Basin, which formed
in a foreland setting as the Early Paleozoic Tobosa Basin but was split in two via Pennsylvanian convergent
forces and structural inversion of the Central Basin Platform. We demonstrate that magnetic data analyses,
combined with station data (heat flow, thermal conductivity, heat production), support thermal property
calculations in the sedimentary basin layer as well as TML. We further demonstrate that these results are
improved by Supervised Learning analyses.
Our method integrates thermal properties with basement terranes interpreted, in part, from magnetic
susceptibilities derived from 3D modeling, to generate thermal models for Delaware and Midland Basins as
well as the Central Basin Platform. These models are refined, employing a suite of Python-based Supervised
Learning algorithms, to compare heat flow prediction from thermal properties in the sedimentary basin
layer with those in the sedimentary basin layer + The Magnetic Layer. We conclude with examples that
connect derived thermal properties with geological elements in the study area.
