Earth’s magmatic systems provide our society with beneficial mineral resources, yet confront us with potentially deadly hazards. To understand these diverse and fascinating systems, we need to know how and where magma is generated, how it moves through the crust, and why it solidifies at depth or erupts at the surface – sometimes as unimaginably large supervolcanoes. Answering such questions entails geologic detective work because the action takes place in the subsurface, well beyond the realm of our direct experience. The work is not easy - it takes keen observers with imagination tempered by knowledge of chemistry and physics. Important constraints on the conditions and timing of magma formation, transport, and solidification are preserved in the compositions of minerals and glass in igneous rocks. Deciphering these clues is an essential first step in the development of accurate physical-chemical models of magmatic systems that can be used in hazard assessment, mineral exploration, and tectonic reconstruction.
Matt Sagar (2008 BSc Hons) documents a Cretaceous pegmatite/aplite dike that cuts mylonite in lower plate of Paparoa Core Complex, Westland. The ages of such dikes provide important constraints on the timing of deformation.
