In general, I am most interested in how magmatic processes, both within the Earth and at the surface of the Earth, change magma compositions and physical properties of the magmas. Ultimately, these changing characteristics significantly impact the behavior of magmas as they rise through the Earth's crust and potentially erupt at the Earth surface. Additionally, some of these processes, such as assimilation of the surrounding rocks, have significant impact of the formation of magmatic mineral deposits and the signatures or these processes can be observed within the igneous rocks they create and be used as tools in the exploration for these deposits.
