my 2015-2016 restoration project (back on the road again)
Rock Types Studied: Studies are largely of basaltic lavas, gabbroic and ultramafic xenoliths in basaltic lavas, the Hawaiian magma system, continental alkalic basalts, continental flood basalts -- and all the minerals assemblages with. Most recently, I have added silicic pyroclastic rocks and lavas to the research mix, particularly from central Arizona.
Instrumentation: Application of my Department's electron microprobe and using the x-ray fluorescence spetrometry data, ICP-MS data, and isotope data obtained from other labs, generally labs of collaborators.
Collaboration: Joint research projects with geology-colleagues in the U.S., Brazil, and Hungary
Graduate student projects:
Thesis research should emphasize igneous or mantle rocks (mainly as xenoliths) that are thoughtfully and meaningfully collected (e.g., above, Arizona volcanics sampled by Brian and Katie) -- and then analyzed for whole-rock major- and trace-element compositions (including REE) using X-ray fluorescence spectrometry and/or ICP-MS and/or INAA, mineral compositions using electron microprobe, and, if possible to obtain and include, Sr-Nd-Pb isotopic compositions (most recently accomplished at Univ. North Carolina-Chapel Hill isotope lab).
Over a two-year period, I teach each of the following at least once: Physical geology (website ); Igneous and metamorphic petrology (for undergrads); Mineralogy; Advanced igneous petrology; and Electron microprobe analysis
I also like to run Fall Break field trips to great places out West, such as Arizona, the Cascades, and New Mexico (above, field trip at the Albuquerque volcanoes, 2006; more NM pictures below). Our Department offers one-credit hour for these 5-day field trips....to have a great time checking out igneous rocks and features, and camping.
Here's our NM field gang in the Black Range, southwestern NM (Oct. 2006)
