Pyroxene Map Geochemistry uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth’s crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the entire solar system and has made important contributions to the understanding of a number of processes including mantle convection, the formation of planets, and the origins of granite and basalt. Our research focuses on the investigation of spatial and temporal variability of element cycles and detailed deductions from the make-up of rocks, minerals and other compounds. We address both fundamental questions such as ‘how old is a rock’ and applied questions such as ‘where and how do the critical elements we need for our new technologies concentrate’.

Fission tracksWe have a diverse portfolio of research, which includes isotope and tephro-stratigraphy, thermal history, tectonic processes and the evolution of magmas. Much of our current work focuses on mapping geochemistry at the sub-microscopic scale. At this scale, the behaviour of chemical elements in solid matter is governed by the exact structure of the surrounding crystal. The quantification of these effects is at the forefront of geochemical research at Trinity and around the world
