Tectonophysics: Plate tectonicsThe proximity of a hotspot to a spreading center may result in the channeling of atmosphere to the section of rise crest closest to the hotspot. This produces more basalt and thicker crust at these locations, thus forming a plateau over time. The geometric ...
Iceland provides an opportunity to understand the formation of silicic rocks in the absence of subduction. This is important for planetary bodies that lack plate tectonics in their history. Crustal thicknesses today on Mars, Venus and the Moon27,49,50 are estimated to be much thicker than Icelan...

The volume of the basalt storage reservoir formation was calculated from the average thickness of the formation (0.4 km), multiplied by an approximate length (2.5 km) and width (1.8 km) of the CarbFix site. Theoretically, if CO2 sequestration is applied along the entire length of the active...
Specifically, we consider that local stress fields created by magma pressure likely dominated during FFD formation, and that they attest to periods of overpressure in the magma reservoir. Polymodal fault sets point to the interaction between the local stress field created by the magma body and the...
