As the west rim of an ejective fold zone, Huaying Mountain fault zone (HMFZ) in eastern Sichuan Basin (SB) plays important role tectonic evolution SB. The distribution and characteristics HMFZ are strongly associated with activities have greatly impacted oil gas reservoirs. However, its remained poorly understood due to a lack geophysical data, especially areal gravity survey magnetotellurics (...

High-resolution magnetotelluric and gravity data have been collected over the Kiejo-Mbaka geothermal field, located along NW–SE trending Mabka fault, in Karonga Rift basin (East Africa System). Such resolution allowed to reconstruct field structure with unprecedented detail. Resistivity modelling has obtained by three-dimensional finite-differences inversion of MT data, while density accomplish...

The Controlled Source Audio-frequency Magnetotellurics (CSAMT) is a geophysical method utilizing artificial electromagnetic signal source to estimate subsurface resistivity structures. One-dimensional (1D) inversion modelling of CSAMT data non-linear and the solution can be estimated by using global optimization algorithms. Particle Swarm Optimization (PSO) Grey Wolf Optimizer (GWO) are well-kn...

The Ordos Block in China experiences tectonic activity and frequent earthquakes due to compression from the Tibetan Plateau extension North Block. This has prompted construction of a high-resolution three-dimensional (3D) deformation field better understand region’s crustal movement. Considering limitations existing geodetic observations, we used InSAR, GPS, leveling observations create high-pr...
