... to integrated modeling of disparate geophysical data types, we discuss using a structural similarity constraint, through 3D crossgradient joint inversion. The examples here look at resistivity and density inversions in a graben setting, including the use of tears in the smoothing regularization, to better...

... ABSTRACT Seaward-dipping reflectors (SDRs) represent flood basalts rapidly extruded during either rifting or initially subaerial sea-floor spreading (Jackson et al., 2000). Where high-quality geophysical data is not available, SDRs can be easily confused with a half graben, when both have...

... ABSTRACT Aeromagnetic data are used to describe the basement in the Espino Graben, Eastern Venezuela sedimentary basin. In this case, the magnetic characterization has an important role that the interpreter has as a tool to understanding the regional structural geometry of this basin...

..., which are characterized by obvious segmentation in strike direction. Local faults developed within each segment frequently show flower structures in profile, and show a variety of combined styles such as linear horst and graben, en-echelon normal faults, pull-apart graben, horse tail faults on the plane...

... Example The composite discontinuity attribute was applied to a 3D seismic survey shot over the Hitts Lake Field, with production over the Paluxy Formation (Caughey, 1977). The main structural features observed in the area are related to normal faulting and salt domes (Jackson, 1982). A series of grabens...

The MT inversion results and the interpretation of the multi-geophysics dataset reveal important structural elements such as deep-seated...

.... These results match with receiver function Moho depth estimates from the EarthScope USArray. We used borehole data and shallow seismic survey results to constrain the upper 5 km of the model along the profile. A number of normal faults that form a series of grabens and half grabens were also modeled beneath...

..., RBF NN was applied to theoretical and Seferihisar geothermal area gravity data to obtain depth and density contrast. Seferihisar is an important geothermal area because of the active graben-horst tectonism and volcanism. There are many geological and geophysical studies in this region. Self-potential...
