Dr. Chloë Bonamici

I am a native of Arizona. I like rocks, being outdoors with rocks, and being indoors with analytical instruments.

Research interests:

Granulites & orogenesis

Using new geochemical tools to look for reliable P-T-t-fluid information on high-temperature metamorphic rocks and the events that produce them.

Mineral zoning & microstructures

Using the spatial variations in mineral composition and texture to investigate the temporal variations in rock conditions.

Complementary microanalysis

Application of multiple microanalytical techniques to a geo-sample in order to develop a comprehensive chemical and isotopic characterization.

Geochemistry of nuclear fallout

The ultimate in high-temperature metamorphism.

Current Group Members

Claudia Roig (PhD student)

Claudia is studying thermal and fluid histories recorded by oxygen isotope zoning in minerals from the Whipple Mountains metamorphic core complex (California, USA). Ask her about epidote!

Khalil Droubi (MS student, co-advised with Dr. Annie Bauer)

Khalil is working on in situ U-Pb and trace element characterization of titanite in rocks of the Acasta Gneiss Complex, Earth's earliest continental crust.

Past Group Members

Dr. Guillaume Siron (former postdoc, now at Università di Bologna)

Guillaume is characterizing intragrain oxygen isotope variations in samples from the Buckskin-Rawhide metamorphic core complex (Arizona, USA) to better understand the thermal and fluid history of the detachment during exhumation. He has also been improving the Fast Grain Boundary inversion algorithm.

Danielle Sulthaus (MS 2019)

Danielle used strain analysis and EBSD-based quartz c-axis fabric analysis to constrain deformation conditions along the Plomo-Pecos shear zone, a major thrust structure active during the ca. 1.4 Ga Picuris Orogeny.

Dr. Adrian Castro (former postdoc, now at Wellesley College)

Adrian worked on constraining P-T conditions of garnet formation and deformation in the Picuris Mountains.

Ke Li (MS 2019)

Ke Li studied alteration of the crystalline rocks along the Great Unconformity to understand the geochemical processes that affect porosity, permeability, and fluid transmission along this horizon. Field work took her to scenic outcrops in northern New Mexico and the Grand Canyon.

Gabe Kropf (MS 2019)

Gabe is an applied mathematician who recently completed his MS thesis on the Fast Grain Boundary model for oxygen isotope diffusion. He updated the software to run in Python and C and expanded it to allow for inversion of oxygen isotope zoning data to retrieve time-temperature histories.
