Current Research

In and east of Death Valley National Park, California and Nevada:

Studies of metamorphic petrology and thermochronology were undertaken in the Funeral Mountains, California, and at Bare Mountain, Nevada. The exposed rocks belong to a 13-km thick sedimentary sequence of Neoproterozoic to Mississippian age. Metamorphism took place when the rocks were buried by thrusting in Mesozoic time. Deeply buried rocks became exposed in Miocene time when crustal extension resulted in the development of a regional detachment fault. The hangingwall slid off to the west-northwest forming the Grapevine Mountains and exposing the metamorphic rocks underneath in the Funeral Mountains and at Bare Mountain. Studies in this area have established the pressure and temperature conditions of the metamorphism, the direction of transport along the fault, and the timing of its movement. For further information, see publications and recent abstracts.


 

Northern Funeral Mountains, view looking north. Gently east-dipping surface in the foreground is a detachment fault. Lower greenschist facies rocks of the Wood Canyon Formation in the hanging wall are juxtaposed against middle amphibolite facies rocks of the Crystal Spring Formation in the footwall, representing a stratigraphic omission of ~7 km and metamorphic discontinuity of ~200 degrees C. In the distance are the Grapevine Mountains.

Northwest Utah and Southern Idaho:

Rocks are being studied in the Raft River Mountains, Grouse Creek Mountains, and Albion Range. All are located in the hinterland of the Sevier orogenic belt. A series of subhorizontal faults juxtapose metasedimentary packages of differing age and metamorphic grade. Some of these faults were probably synconvergent normal faults. Two major shear zones and a Miocene detachment fault were responsible for the exhumation of the terrain. Studies of this area involve metamorphic petrology, 2-d numerical thermal modeling, thermochronology, geologic mapping and structural kinematics. Numerical simulations of garnet growth in pelitic schist document a pressure increase of 2.5 kb at constant temperature, corresponding to the emplacement of a 9-km thick thrust sheet (see garnet pictured below). This work is collaborative with Dr. Michael L. Wells at the University of Nevada, Las Vegas. For further information, see list of publications and recent abstracts. There is current NSF funding to support graduate student research on this project.

Graduate Research Opportunites. I have current (will be available through 2010) funding from the National Science Foundation to pursue studies in the Funeral Mountains (Death Valley National Park, California) and in Northwest Utah. The focus of this project is to determine pressure-temperature from garnet growth zoning, dating the paths using the Lu-Hf method, and comparing to numerical simulations of tectonic processes in an effort to understand the mechanism that triggers extension at depth during compression in orogens.  The work is collaborative with structural geologist Dr. Michael Wells (UNLV) and isotope geochemist Dr. Jeff Vervoort (WSU).  The work will likely involve one or more trips to the SHRIMP-RG (Sensitive High Resolution Ion Microprobe – Reverse Geometery) lab at Stanford University. In addition to the four semesters of Graduate Assistant salary normally given to graduate students to teach undergraduate laboratory courses, the student on this project will receive at one additional semester of salary to conduct research.  The grant will also cover research (field and laboratory) expenses.  Please contact me if you are interested in pursuing graduate research studies at NAU on this project.

An article featuring my graduate student Cici Cruz-Uribe was published in the Winter 2009 newsletter of the NAU Graduate College.
