Multifunction waveform generator for EM receiver testing [PDF]
In many electromagnetic (EM) methods – such as magnetotelluric, spectral-induced polarization (SIP), time-domain-induced polarization (TDIP), and controlled-source audio magnetotelluric (CSAMT) methods – it is important to evaluate and test the EM ...

Abstract A small phreatic eruption occurred on April 2018 Iwo‐yama, Kirishima volcanic complex, Japan. We estimated the change in the subsurface resistivity structure before and after the phreatic eruption by repeated magnetotelluric (MT) measurements. A substantial decrease in resistivity was determined in the zone from the surface down to a depth of ...

Unconformity‐related uranium (URU) deposits in the Athabasca Basin, Canada, include the highest grade, large tonnage deposits in the world. Recent studies of the Patterson Lake corridor uranium deposits suggest a deep heat source enhances hydrothermal ...

Abstract Since the Mesozoic, much of the eastern China lithosphere was removed through thermo‐mechanical erosion and delamination, yet the effects on the overlying crust remain unclear. The Tanlu Fault Zone (TLFZ), the region's largest lithosphere‐scale weakness, offers a natural laboratory to assess crustal responses to lithospheric destruction.

Abstract The Alabama–Oklahoma Lineament (AOL) is a major crustal boundary that intersects the Mississippi Embayment (ME) and may influence intraplate deformation in the southern United States. We present the first regional magnetotelluric (MT) resistivity models across the AOL–ME system using EarthScope data and two‐dimensional inversion. All southwest–

Autocorrelation Seismic Imaging of Northern Taiwan Using Ambient Noise Data
Abstract Over the past few million years, northern Taiwan records a tectonic history of subduction to arc–continent collision followed by post‐collisional collapse. This evolution motivates constraints on crustal structure, including crustal layering and thickness.

The deep electrical structure of Motuo fault zone in Beibeng area
To elucidate the contact relationship between Indian and Eurasian plates along the Yarlung-Zangbo suture zone (IYS) and associated geodynamic processes, we acquired a high-resolution magnetotelluric (MT) profile extending 20 km across the Motuo fault ...

Exploring Enceladus's Interior Structure Using Electromagnetic Induction
Abstract Electromagnetic (EM) sounding can constrain the electrical structure of Enceladus and, in turn, the salinity of its ocean and the porosity, fluid content, and thermal state of its hydrothermally active core. Here, we assess the feasibility of EM sounding at Enceladus using both global (orbiter) and local (lander) EM induction transfer ...

A workflow for cooperative inversion of seismic and magnetotelluric data
We present a cooperative inversion approach for acoustic impedance using seismic and magnetotelluric data. In this approach, the magnetotelluric data, sensitive to the resistivity of rocks are used to get the large scale background spatial trends of the ...

Depth model building by constrained magnetotelluric inversion
In this paper we describe an approach aimed at integrating seismic and magnetotelluric data in a complex geological setting, characterised by thrust structures, in Southern Apennine, Southern Italy.
