This archive contains 3D gravity inversion results and methodology. The 3D geophysical modelling was performed using the open source SimPEG code (www.simpeg.xyz). The input and output geophysical model files are provided in UBC format (more information on UBC format files can be found at: gif.eos.ubc.ca). The output density model file has also been supplied in .txt file format. The 3D gravity modelling exercise at Fallon FORGE was guided by: a) a 3D geologic model developed by the FORGE team and b) rock density measurements made in Phase 2B. This information is provided elsewhere in the GDR. The core of the 3D model volume used in the gravity modeling exercise has the following dimensions: 8 km (N-S) x 8 km (E-W) x 4 km (thick). This core model volume is centered on the Fallon FORGE site. The majority of the core model volume has 100 m x 100 m x 100 m cubic cells. Near the land surface, model cells are as thin as 1 m to adequately capture variations in topography. All horizontal coordinates in the input and output files are in UTMNAD83 zone 11. All elevations are in meters above sea level.
