Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]

open access: yes, 2008
Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

Geology-geophysics integrated inversion in Mount Isa South, Queensland

open access: yes, 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
