This theory of oceanic magma mixing is important because it could represent a transitional step in the formation of back arc basins -- an important geological structure that shapes landscapes ...

The opening and closing of the Rocas Verdes Basin, a back-arc basin in Patagonia, as described by researchers at The University of Texas at Austin in a study published in Geology. Panels B and C ...

Deposits are found at tectonic plate boundaries along the mid-ocean ridges, back-arc ridges and active volcanic arcs, typically at water depths of around 2,000 metres for mid-ocean ridges.

as well as other plate boundaries such as the Tonga, Mariana, and Philippine Trenches, various fracture zones, seamounts and back arc basins. These expeditions have contributed many tons of basaltic ...

Encarnacion is interested in a variety of tectonic and petrologic problems dealing with subduction, magmatism, island arc and continental crustal growth as well as ore deposits. His research has taken ...

Scientists use tiny minerals called zircons as geologic timekeepers. Often no bigger than a grain of sand, these crystals ...
