New Stuff:

Our interdisciplinary team of geochemists, geophysicists, structural geologists, and hydrogeologists was awarded a 2017 Keck Science and Engineering Grant for our project Evolution of Crustal Paleofluid Flow Systems. Photo by Amanda Hughes.

Our book Geochronology and Thermochronology is a comin'...maybe by December 2017...

New photos from The 2016 ConocoPhillips-UA Geosciences Southern Utah Fieldtrip, April 2016

Less New, But Still Newish Stuff:

Watch Martin Pepper's awesome new videos of UA Geosciences' world-renowned field camp. Here is a sweet 12-minute version, and here is a beautiful 40-minute version to make you wish you did more fieldwork.

GEOS 474/574: Geochronology & Thermochronology, Spring Semester 2016

Stuff that's starting to wear out its newness, but I don't want to take down and you might find interesting:

My student Victor Garcia has a new website about his work on Fe- and Mn-oxides associated with faults and diagenetic cement in Utah.
•Having trouble sleeping? Hoping to become even more confused about diagenesis? Looking for amazing examples of voiceovers and cutaways? See Marty Pepper's new blockbuster youtube video, Moki Marbles Matinee.
Dr. Willy Guenthner () has a new website at his new institution, the University of Illinois.
Check out our cover photo and new paper on diagenetic cement, concretions, and fracture-filling oxide minerals in Mesozoic sandstones of the Colorado Plateau, in GSAB, August 2014.
New photos (Aug 2014) from HeDWAZ 2014 - Multichron, June-July 2014
My former student Devon Orme's new website.
Field trip to the Colorado Plateau to investigate the mysteries of diagenetic oxides, October 2013
Field trip to the Uinkaret Volcanic Field, October 2013
•September 2013: I'm back at UA and in the thick of things again. Just to show you what I've been up to lately, here is a shot of some of my favorite secondary minerals from my favorite place in the world.
August 2012 to August 2013: I'm on sabbatical, at the Centre de Recherches Petrographiques et Geochimique (CRPG).
Check out Stuart Thomson's recent paper on the landscape evolution of subglacial East Antarctica. This got a nice News & Views, and some good publicity, for example here, here, and here. This is also closely related to UA alum Clare Tochilin's cool paper on Antarctic erosion, here.
Check out the recent paper led by Jay Quade on the mysterious rubbing boulders of the Atacama, in here:

. And while you're at it take a gander at some of the cool SEM pics in the oft-overlooked DR. What up with the Si-coating?

I'm a Professor here in Geosciences at the University of Arizona, since August 2006, where I work on thermochronology, geochemistry, tectonics, and petrology. Before that I received my PhD in Earth and Space Sciences at the University of Washington , did a postdoc in the Division of Geological and Planetary Sciences at the California Institute of Technology , and was on the faculty in the Department of Geology at Washington State University, and in the Department of Geology & Geophysics at Yale University.
