Motivated by the idea that Curie point depth is also a temperature horizon (∼580°C where cooling iron becomes magnetic), we present a new method to integrate basement terrane and high-resolution magnetic basement depth interpretations with open-file station and well data to map thermal properties in sedimentary basins and TML, including temperature, thermal gradient, thermal conductivity, heat flow, heat production, and heat production layer thickness.Keywords: magnetics, heat flow, thermal properties, basin modelPermalink: https://doi.org/10.1190/image2022-3750584.1FiguresReferencesRelatedDetails Second International Meeting for Applied Geoscience & EnergyISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2022 Pages: 3694 publication data© 2022 Published in electronic format with permission by the Society of Exploration Geophysicists and the American Association of Petroleum GeologistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 15 Aug 2022 CITATION INFORMATION Dale E.
