The Trans-Mexican Volcanic Belt (TMVB) stretches 1,000km along the southern edge of the North American plate, generating a wide range of igneous products and processes.
The TMVB is an active continental arc that formed around 11 million years ago. The variable composition of its igneous products and volcanic style make the TMVB a particularly interesting subduction zone to study.
Previous TMVB research has identified:
Our current research projects include:
We are exploring the geodynamics of mafic and ultramafic rock complexes in southern Mexico and the economic potential for their exploitation.
We are investigating the occurrence of adakite rocks and the role of subducted plates in arc magmatism.
A tectonic plate boundary where one oceanic plate moves beneath another plate. Often associated with volcanoes, earthquakes and mountain building.
A chain of volcanoes formed above a subduction zone.
The formation of igneous rock from the cooling and solidification of magma.
Silica-rich igneous rocks formed in subduction zones, characterised by high strontium/yttrium ratios and low yttrium and ytterbium content.
