Summary

Regional grid files and 3D voxel models were 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 grid files consist of surface grids (magnetic field observation surface, topographic surface, Precambrian basement surface, and Moho interface) used to construct templates and initial physical property models for 3D inversions, observed geophysical data grids (Bouguer gravity anomaly and reduced-to-pole (RTP) aeromagnetic anomaly) used in the inversions, and calculated geophysical [...]

Purpose

The grid files and 3D voxel models were used to study crustal architecture beneath the Southern Midcontinent (USA) related to transport of ore-forming fluids from the upper mantle to shallow-levels within the Precambrian crust.
