Mihai N Ducea
Professor of Geology
Tectonics and petrology
I am a petrologist interested in tectonic problems. I address geologic problems concerning the evolution of orogenic regions primarily using petrologic and geochemical data. I am also interested in radiogenic isotope geology and oversee several geochemcial laboratories.

My beloved Fagaras Mountains In Romania, where I discovered my passion for geology.
Geos 251: Physical Geology (on rotation with several other faculty)
Geos 356: Undergraduate Petrology
Geos 414; Field Camp (alternating years)

I oversee the following laboratory facilities: a rock preparation lab that includes rock crushing, mineral separation facilities, a micro-sampling facility where we can spatially control the sampling of materials at tens of micron scales, a clean laboratory where we dissolve samples, and perform chemical separations for various elements, an ICP-MS laboratory equipped with a Thermo X-Series 2 instrument where we measure trace elemental compositions of various materials in solution and a TIMS laboratory equipped with two multicollector VG instruments where we measure a variety of radiogenic isotopes. If you are interested in having work done in any one of these labs please contact me or laboratory technician Derek Hoffman (firstname.lastname@example.org
Clean lab and mass spec.
