New perspectives on Solid Earth Geology from Seismic Texture to Cooperative Inversion [PDF]
Scientific Reports, 2019 AbstractSeismic and electromagnetic methods are fundamental to Solid Earth research and subsurface exploration. Acquisition cost reduction is making dense 3D application of these methods accessible to a broad range of geo-scientists. However, the challenge of extracting geological meaning remains.

Geology-geophysics integrated inversion in Mount Isa South, Queensland
, 2023 Taking advantage of all available information including geological and geophysical datasets is important to understand the subsurface. Integration of geological and geophysical datasets is commonly limited to the interpretation of areaspecific case studies and has seldom been addressed by automated techniques. Considering, the geometry of rock units as
