Meteoritics &Planetary Science, EarlyView.Abstract We investigated the structural framework of the north–northwestern Paraná Basin in Brazil to test whether the pre‐impact structures in this region may have had any influence on the first‐order formation and morphostructure of the Araguainha impact structure (AIS).

Practical Magnetotellurics [PDF]
Eos, Transactions American Geophysical Union, 2006 Practical Magnetotellurics lives up to its title and nicely fills a big hole in the literature on the subject of the magnetotelluric (MT) method, a means by which the geological and physical properties of the crust and mantle may be studied using electrical conductivity images.In an MT sounding passive time series, measurements of the Earth's naturally

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The Tan‐Lu Fault Zone (TLFZ), the largest lithosphere‐scale strike‐slip fault in eastern China, has experienced multiple tectonic stages and remains high seismic activity, including the 1668 Tancheng earthquake (M 8.5). Here we employ dense‐array receiver functions to resolve crustal thickness, Vp/Vs ratio, and seismic discontinuities in the ...

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2021 This paper presents the results of application of the approach, previously not used at the Research Station of the Russian Academy of Sciences in Bishkek, to determine the quasi-optimal value of the regularization parameter for the inversion of the ...

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The Tangra Yumco Rift (TYR) in central Tibet is a key window for crust–mantle interactions during extension. We performed high‐resolution crust‐mantle imaging using receiver function analysis, 1‐D nonlinear S‐wave velocity inversion, and tomoDD tomography, revealing a vertical Crust–Mantle Degassing System (CMDS) bounded by the Zhala (ZF) and ...

Magnetotelluric sampling theorem
Earth, Planets and Space, 2023 Abstract We consider a general case of a magnetotelluric (MT) study to reveal three-dimensional (3D) distribution of the electrical conductivity within the Earth based on measurements of electromagnetic (EM) fields by a two-dimensional (2D) array.

Near Surface Geophysics, Volume 24, Issue 3, Page 234-251, June 2026.Abstract A better understanding of the near‐surface aquifer system of the Caxambu Water Park, located in the Minas Gerais State, Brazil, has been achieved. The study aimed to identify groundwater reservoirs and flow patterns and contribute to the hydrogeological conceptual model using a multi‐scale geophysical approach.

The United States Magnetotelluric Array and the National Impedance Map
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.Abstract Interactions between the Antarctic Ice Sheet and the underlying solid Earth occur within the ice‐bedrock interface zone (IBIZ), containing structures of sediments and rocks that strongly influence ice sheet dynamics. Existing insights into the Antarctic IBIZ come primarily from interpretations of airborne geophysical data and active seismic ...
