Current Research Interests

In the past, my research focused on the petrology of the continental crust. Work by my research group showed that few granitoid rocks in nature are pure anatectic melts - peraluminous leucogranites are the only ones that fit this description. Most other granitoid rocks represent hybrid magmas, that contain variable but always important contributions of mantle material. We have shown experimentally that formation of hybrid granitic magmas is accompanied by formation of hybrid mafic cumulates (gabbronorites, norites, garnet pyroxenites) that resemble those that are thought to make up much of the lower continental crust. We have also shown that pressure and influx of aqueous fluids control the composition of granitic melts on an equal footing with source composition, showing that the assumption that “granites image their sources” is generally not warranted. 

Other past research, in collaboration with Mike Roden, focused on the use of accessory mineral phases to infer volatile reservoirs and pathways in the terrestrial planets. The focus has been on using phosphate assemblages (apatite ± merrillite) to determine halogen and water fugacities in the mantles of Mars, Earth and the Moon. Perhaps our most important finding was to show that the Martian mantle must be drier than the terrestrial mantle (Patiño Douce et al., 2011).

Other Academic Interests

Over many years of teaching Earth Sciences I have become aware of (and frustrated by) the widespread perception, among most geology students as well as many earth sciences professionals at all levels, that ours is a science that sits in splendid isolation of physics and chemistry. Because I feel very strongly that this is not the case, I have become interested in reshaping education in the Earth and Planetary Sciences by focusing on physics and chemistry first, and teaching students at all levels to think of planetary processes as nothing more than specific examples of physico-chemical processes. My textbook Thermodynamics of the Earth and Planets, published by Cambridge University Press in 2011, shows how to accomplish this.
