RESEARCH INTERESTS

My main expertise is in igneous and metamorphic petrology and trace-element and isotope geochemistry.  However, my desire is to be a natural historian of the Earth. More specifically, I wed observations in the field and in the lab with theory to better understand the evolution of planetary bodies, the Earth's mantle and continents, the atmosphere, and the biosphere.  My tools are my eyes, the rock hammer, state-of-the-art geochemical facilities, mathematical modeling, and yes, old books and maps.  I am particularly interested in the Earth as a system, connecting the deep Earth to the atmosphere.

The origin and evolution of continents.  The Earth's surface is made of continents and ocean basins. Continents ride high because they are thick and made of rocks that are chemically buoyant with respect to the upper mantle.  Continents are underlain by felsic crust, which are further underlain by chemically depleted residual lithospheric mantle.  What are the petrogenetic and tectonic processes that drive the chemical differentiation of continents? How have these processes changed in time? What are the geochemical implications of continent formation? Much of my work focuses on magmatic differentiation in volcanic arcs, arguably one of the dominant players in making continental crust.  We also examine the deep lithosphere of continents using crustal and mantle xenoliths.

Composition of the mantle and its evolution in space and time.  Extraction of continental and oceanic crust leaves behind a depleted mantle residuum resulting in net unmixing (differentiation) of the Earth.  Recycling of crustal and atmospheric components back into the mantle at subduction zones introduces small-scale heterogeneities, but in fact is a means of rehomogenization the mantle and crust (contrary to what most people say).  One of our goals is to investigate the compositional evolution and heterogeneity of the mantle.  Most studies currently focus on isotopic heterogeneities in the mantle, e.g., the mantle "zoo".  However, our approach is to focus on major-element heterogeneities because the major-element composition dictates the mineralogy and hence physical properties of a rock.  Towards these ends, we are marching through the first row transition metals, all of which are compatible to moderately incompatible during melting, as tracers of mineralogy in the source.  This information allows us to estimate the elastic properties and densities of mantle rocks so that geophysicists can be interpret seismic observations.

Lithosphere-asthenosphere dynamics.  The nature of the lithosphere-asthenosphere boundary and how it evolves with time is critical to understanding the stability of continental and oceanic boundary layers, and more generally, the nature of plate tectonics.  A key parameter in defining the lithosphere-asthenosphere boundary is the temperature of the asthenosphere and base of the lithosphere.  We are developing new tools for estimating the temperatures and pressures of primitive magmas in an attempt to map out the thickness of the lithosphere in tectonically active environments, such as western North America, northeast China, and the western Mediterranean. Specific questions are how fast do continents rift, do continents delaminate during orogenies, and do small-scale convective instabilities efficiently erode the lithosphere?

Redox evolution of the Earth.  The Earth's oxidation state is vertically stratified, consisting of a highly oxidized atmosphere and a reduced deep-interior, collectively bounding an uppermost mantle with intermediate oxidation states.  The Earth's atmosphere, however, was not always oxidized, and there is considerable debate over whether the upper mantle's oxidation state has increased or decreased with time.  Regardless of how Earth's redox has changed with time, the fact that the Earth is redox-stratified means that the interfaces between these layers are characterized by strong voltage differences. The Earth is esentially a charged battery.  We are developing tools based on transition metal geochemistry to quantify the oxidation states of ancient magmas and their mantle source regions.  We have so far focused on V, Sc, Zn, Fe and Cu.  We are deeply interested in the redox evolution of arc magmas.

Economic Geology, Mineral Resources, and Petroleum.  Because of our interests in redox and first row transition metals, we have naturally begun to work on the origin of ore deposits.  Ore deposits are fundamentally mysterious.  They are a paradox in their own right.  In order to form an ore deposit, trace metals from a vast region of the Earth must be scavenged and then concentrated in a very small volume. Thus, these metals must first be mobilized and then immobilized.  The perfect convergence of conditions is ultimately related to redox.  We are presently most interested in the origin of Copper porphyry deposits.  Do they ultimately come from oxidized sources? Why are they so rare when arc environments are thought to be highly oxidized?  Why is there so little Copper in the continental crust?  We are also interested in what makes certain time periods in Earth's history ideal for generating hydrocarbon source rocks, and are currently developing new models.  Finally, we have started working on the origin of unconventional rare earth element (REE) deposits as well as new, environmentally conscious ways of recycling REEs. 

Volcanology and magma differentiation. What physical processes govern the composition and emplacement characteristics of magmas?  Why do some magmas erupt and others intrude to form plutons?  What processes govern the compositional diversity of magmas?  Are there fundamental differences between erupted liquids (lavas) and intrusive liquids (magmas)? What proportion of continental crust is built by intrusive compared to extrusive volcanism?  How can we wed petrology and geochemistry with the physics of magma mingling, crystallization and wallrock assimilation? We are currently studying several field sites to address these questions.


climate

Long-term climate change. The Earth's atmosphere is to a large extent "buffered" by the Earth's interior.  For example, over long (>1 My) timescales, volcanic and metamorphic degassing are the main inputs of CO2 into the atmosphere while chemical weathering and organic carbon burial are the main outputs of CO2.  We also know that the Earth does not give up free O2 because all O2 is bound up in silicate or oxide minerals (e.g., rocks!).  Atmospheric O2 comes ultimately from reduction of CO2 to CH2O, liberating O2 in the process.  Thus, the O2 budget of the Earth's atmosphere is controlled by the CO2 cycle, which itself is controlled by the composition and frequency of volcanic eruptions. All of this together must be intimately linked to the thermal and dynamic history of the Earth's interior, the origin and evolution of continents, and the origin of life.  This is what interests me the most right now.

Evolution and ecology. My favorite past-time when I'm not getting paid is field biology and ecology.  I am interested in ornithology and to a lesser extent botany.  I conduct natural history surveys in Texas and other places I happen to visit. I am also interested in the evolution of species and how this relates to the history of our planet. I do not formally take students to work with me on these endeavors because we do this only on our spare time.
