Magnetotelluric (MT) and magnetovariational (MV) investigations can provide original information and constraints on the electrical conductivity, thermal state and structure of the crust and mantle at the base of the polar ice sheets. These methods provide depth resolution, lacking in potential field methods, and can reach high investigation...

North Victoria Land (NVL) features two major tectonic elements: the Transantarctic Mountains (TAM), forming the uplifted flank of the Mesozoic and Cenozoic West Antarctic Rift System, and the Wilkes Subglacial Basin (WSB). Structure of the TAM rift flank has been partially investigated with different geophysical approaches. To the West, the...

We have analyzed the deep conductivity structure at the transition between the Transantarctic Mountains (TAM) and the eastern margin of the WSB in NVL, by means of the GDS (Geomagnetic Deep Sounding) technique, in order to constrain the geodynamical interpretation of this antarctic sector. The TAM form the uplifted flank of the Mesozoic and...

This paper illustrates the first results of the geological, geochemical and geophysical investigations in the Alalobeda geothermal field located in the Tendaho Graben, Northern Afar Region (Ethiopia). The tectonic pattern of the Alalobeda field is characterized by the superposition of three regional rift zones: the Red Sea (NW-SE), the Main...

The Dubti and Ayrobera geothermal systems are located in the Tendaho Graben (Afar region, Ethiopia). As part of the ARGeo 2014 program, we have integrated the available geophysical data set with new measurements. The new residual magnetic anomaly map has been used to map the younger (<0.78 Ma) normal polarity basalt distribution and infer the...

A geothermal exploration project was founded by the Icelandic International Development Agency (ICEIDA) and the Nordic Development Fund (NDF), with the aim of assessing the geothermal resources of Alalobeda (Ethiopia). The Alalobeda geothermal system is located along the western margin of the Tendaho Graben, where the NW tectonic structures...

The Alalobeda geothermal system is located in the Afar region (Northern Ethiopia), along the western margin of the Tendaho Graben. A multidisciplinary geoscientific study of the Alalobeda geothermal field, was funded by the Icelandic International Development Agency (ICEIDA) and the Nordic Development Fund (NDF), and carried out by the...
