Crustal Architecture Beneath the Southern Midcontinent (USA) -- Data Grids and 3D Geophysical Models: 3D Voxel Model of Magnetic Susceptibility

Metadata Updated: October 29, 2023

This 3D voxel model of magnetic susceptibility in GOCAD format was used to study crustal architecture beneath the Southern Midcontinent (USA) by McCafferty and others (2019). The study covered a rectangular, multi-state area of 924 by 924 kilometers centered on Missouri, and a corresponding volume extending from the topographic surface to a depth of 50 kilometers below sea level. The 3D voxel model describes the magnetic susceptibility of the crust as interpreted using 3D inversion. The masked version excludes magnetic susceptibilities in areas where the Precambrian basement surface elevations are unknown. The individual voxel elements are 2,000 by 2,000 meters by 500 meters thick. Missing data nodes are assigned a value of -99999.
