Chloe
Glover
Chloe just finished her first field season in the Peruvian Andes! She will be looking at how geometry
of shortening and the age, magnitude and rate of exhumation change between the
Andean plateau in southern Peru and the more narrow fold and thrust belt in
central Peru.
Victoria
Buford
I am researching the kinematic, flexural, and
thermal history of the Central Andean fold thrust belt in Bolivia and Peru.
Geologic maps, field observations, and structural cross sections will be
integrated with thermochronologic data to create a thermal and structural
evolution of the Central Andes, with an emphases on southern Peru. These
balanced sequential restorations provide a complete kinematic reconstruction of
the Central Andes, allowing us to quantify and analyze the relationships
between the subsurface structural geometry and the magnitude of uplift and
exhumation.
Suryodoy Ghoshal
My research will be to develop a suite of
kinematic and thermal models of the Central Nepal Himalayas. I will evaluate the proposed geometry
and kinematics of a number of published cross sections to see if the predicted
cooing ages from the published geometries match the measured cooling ages in
the region. Based on the
matches and mismatches between measured and predicted ages I will propose new
cross section geometries that will match all available surface and subsurface
constraints including the wealth of published cooling ages through the
region. The resulting thermokinematic model of the region will allow us to
constrain the relationships between uplift, uplift rates, geometry and
exhumation.

Paul R.
Eizenhofer (Humboldt Post-doctoral Fellow)
Paul focused on reconstructing
fault motion, rock uplift, erosion and exhumation across the Himalayan fold-thrust
belt in eastern Bhutan. In particular, he wanted to explore to what extent the
foreland basin sedimentary record can provide constraints on the
thermo-kinematic history of the region for the past ca. 20 million years. This
involved the integration of multiple approaches that model fold-thrust belt
kinematics, crustal flexural responses, crustal thermal fields and landscape
evolution in order to predict detrital thermochronological
ages, and match these with measured data. To get there he started exploring
the relationship between uplift, horizontal transport and got distracted by
some really cool modeling approaches that integrates thrust belt kinematics
with landscape evolution.
Paul has moved on to University of Tuebingen
in Germany.
Joshua Olsen (MS University of
Pittsburgh 2017)
Joshua created kinematic and flexural/erosional
models of cross sections in western Nepal in order to refine the geometry,
sequence, and relative age of faulting as we as refine estimates of total
shortening in the Himalayas. The
kinematic and flexural models are being used now as input into the thermokinematic modeling program Pecube
in order to predict the pattern of cooling ages imparted by different
geometries and kinematics. This
approach allows us to further refine the geometry o the cross sections based on
the match between the predicted and measured cooling ages.
Ashley Ace (MS University of
Pittsburgh 2016)
Ashley utilized seismic data to best constrain
the structural geometry of the Appalachian Mountain front. Using field data,
interpretations of a volume of seismic data, and stratigraphic constraints, She
creating a 3D kinematic model to illustrate the style and magnitude of
deformation of the Allegheny front.
Michelle Gilmore (MS University of
Pittsburgh 2014; Research assistant 2015)
Michelle explored the spatial and temporal evolution of deformation
and exhumation in fold-thrust belts. Utilizing geologic maps of Bhutan as well
as new and existing balanced cross sections and thermal cooling data, she evaluated the links
between structural and topographic change over time, and how those changes are
expressed in predicted cooling ages.
She used combined forward kinematic and thermal modeling of cross
sections to analyze relationships between erosion, deformation, displacement
rates, geometry and exhumation.
Michelle is currently the outreach and education manager with the
southern Sierra Critical
Zone Observatory, Her Masters work was just published in Solid Earth (Gilmore et al.,
2018)
Adam Rak (MS
University of Pittsburgh 2015)
Adam evaluated the kinematic history of
the Central Andean fold and thrust belt in predicted ages northern
Bolivia. He linked a sequentially
restored balanced cross section to published thermochronologic ages through the
thermal advection diffusion model Pecube. Matching to measured ages allowed us to
test how sensitive the predicted ages are to the age, rate and geometry of deformation.
This research was published in Tectonics (Rak
et al., 2017). Adam currently works
as a Exploration Geologist at Arsenal Resources (adamrakgeo@gmail.com)
Bobak Karimi (PhD University
of Pittsburgh 2014)
Bobby
focused on geophysical modeling strike slip faults. In particular, determining
fault geometries and constraining fault properties (cohesion and fault
friction) along the western North Anatolian Fault (NAF), Turkey.
He
is currently an Assistant Professor at
Wilkes-Barre University, PA.
Garrett Tate (PhD Princeton 2014)
Garrett integrated structural mapping, balanced
cross-sections, thermochronology, geomorphic analyses
and uplift histories to quantify the magnitude of continental subduction in Timor and constrain highly variable histories
of surface uplift and exhumation in young orogens. He is now a Assistant
Research Professor and Senior Lecturer, Vanderbilt University, TN.
Nate Eichelberger
(PhD Princeton 2014)
Nate focused on developing a comprehensive
structural model of the Central Andean (or Bolivian) orocline.
He combined field observations with shortening estimates, paleomagnetic
data, micro-scale strain observations, and thermochronology
to reconstruct the three-dimensional evolution of orocline
system over time. Nate is working
for StructureSolver based out of California.
