Insight from thermochronology, magnetotellurics, and structural analysis into the tectonic evolution of the Ozark Dome-Illinois Basin region, Midcontinent USA
The north-central Midcontinent of the United States lies within the cratonic platform of North America, a geological province characterized by a thin veneer of Phanerozoic sedimentary cover strata overlaying Precambrian basement. (The boundary between the cover and the basement is the Great …

Usability Engineering Applied to an Electromagnetic Modeling Tool
… that allows users to parameterize the 2D magnetotellurics problem. Through the evaluation of this interface, feedback was collected from a usability specialist and a group of geophysics graduate students to study the steps users take to work through the 2D forward-modeling problem, and to …

Three-dimensional magnetotelluric modelling of the Taupo Volcanic Zone, New Zealand
… This contrast makes the geophysical method of magnetotellurics (MT) an ideal tool for the imaging of subsurface structures in the TVZ. This thesis discusses the 3D modelling and interpretation of a large MT dataset from the central TVZ. Although MT is an important tool in geophysical …

Physics-based and data-driven inversion of magnetotelluric data for subsurface imaging
Electromagnetic (EM) geophysical inversion is fundamentally limited by the ill-posed and non-unique nature of the inverse problem, where diffusive physics, limited depth sensitivity, and observational noise lead to broad sensitivity kernels and multiple admissible subsurface models. Conventional …

Magnetotelluric measurements across the southern Barberton Greenstone Belt, South Africa
Der Barberton Grünsteingürtel (BGB) in Südafrika gehört zu den wenigen Regionen mit noch gut erhaltener Archaischer Kruste. Seit Jahrhunderten wurde der BGB eingehend untersucht und seine geologischen und tektonischen Strukturen detailliert kartiert. Über die tiefere Struktur des BGB ist hingegen …

Seismic structure of the Arava Fault, Dead Sea Transform
Ein transversales Störungssystem im Nahen Osten, die Dead Sea Transform (DST), trennt die Arabische Platte von der Sinai-Mikroplatte und erstreckt sich von Süden nach Norden vom Extensionsgebiet im Roten Meer über das Tote Meer bis zur Taurus-Zagros Kollisionszone. Die sinistrale DST bildete sich …
