Brian Horton holds a joint appointment with the Department of Geological Sciences (Professor) and the Institute for Geophysics (Research Professor) at UT-Austin.

Brian's research focuses on the tectonics of sedimentary basins, evolution of orogenic systems, sediment provenance and routing systems, and nonmarine depositional processes. He combines field-based basin analysis with sedimentology, geologic mapping, geochronology, magnetostratigraphy, petrography, geochemistry, and basin modeling to address the evolution of modern/ancient basins and associated structures.

Graduate Students

Tomas N Capaldi, Ph.D., expected 2019 (Supervisor)
I am a first year PhD student, focusing on Cenozoic to modern tectonic evolution of the dissected Bermejo foreland basin in western Argentina. My research involves clastic sedimentology and stratigraphy, provenance and geochronology, low-temperature thermochronology, and petrography. By applying these various techniques I will better understand the style and timing of upper-crustal deformation associated with ongoing Pampean flat slap subduction.

Lily Jackson, Ph.D., expected 2019 (Supervisor)
My current research focuses on determining timing and magnitude of major paleo-elevation changes affecting the Peruvian Andes. My current methods include detrital zircon geochronology, hydrogen stable isotope paleoaltimetery with volcanic glasses, and traditional methods in sedimentology.

Amanda Z Calle, Ph.D., expected 2017 (Supervisor)
My research is focused on the Cenozoic sedimentary, structural and exhumational history of the Eastern Cordillera to modern Chaco foreland basin in southern Bolivia. A multidisciplinary approach of source-to-sink, geochronology, low-temperature thermochronology and structural mapping will be used. Inherited pre-Andean structures and their response to contractional settings will also be evaluated to decipher the Cenozoic evolution of this part of the Central Andes.

Renas I Mohammed, Ph.D., expected 2016 (Supervisor)
Renas is working on the Zagros fold-thrust belt and foreland basin in Iraq's northern region, Kurdistan. His fields of interest are assessing the effect of sedimentation on deformation sequence and styles, and the controls on wedge dynamics of the northwestern Zagros orogenic belt. He is also interested in understanding the competitive role of axial and transverse drainages in filling sedimentary foreland basins and how sediment dispersal pattern change in response to thrust propagation. In his research, Renas employs field geology (sedimentology/stratigraphy and structure) integrated with a variety of analytical techniques such as: U-Pb geochronology, (U-Th)/He thermochronology, magnetostratigraphy, and petrography. Renas has obtained his MS degree at the University of Texas at Austin in 2011. Currently, he is a PhD student in the same school.

Meredith A Bush, Ph.D., expected 2016 (Supervisor)
Meredith is a fourth year PhD student, focusing on the evolution of contractional mountain belts and intra-continental basins. Meredith is interested in the tectonics of sedimentary basins in intra-continental settings, clastic sedimentology and provenance analysis. Her current field areas include the Qaidam basin on the Tibetan Plateau, the Raton basin in Colorado and New Mexico, and the Galisteo-El Rito basin of New Mexico. Her research includes a variety of analytical techniques, including magnetostratigraphy, detrital mineral geochronology, heavy mineral analysis and sandstone petrography.

Sebastian G Ramirez, Ph.D., expected 2016 (Supervisor)
I am currently working on two sub-projects. The first aims at understanding the conditions of Kumano forearc basin (offshore Japan) nucleation and early evolution through 3D-seismic and sandstone petrography provenance analyses. The second involves the study of the Cretaceous-to-Recent sedimentary record in the northernmost Neuquen basin (western Argentina) through traditional field work and detrital zircon analysis. My goal is to better constrain the timing and characteristics of early Andean compression and to test whether or not the observed deformation patterns might be associated with subducting slab shallowing/steepening cycles.

Nicholas D Perez, Ph.D., expected 2015 (Supervisor)
My work focuses on understanding the Cenozoic deformation history of the central Andes of southern Peru. I use a mix of basin analysis (sedimentology/stratigraphy, provenance, geochronology) and structural (field mapping, balanced cross sections, thermochronology) techniques. With this work I will address questions regarding the timing and mechanisms responsible for crustal thickening found in the central Andes. I am also interested in how inherited structures influence subsequent shortening and basin development in orogens.

Veronica J Anderson, Ph.D., expected 2015 (Supervisor)
My research focuses on understanding the tectonic history of the Eastern Cordillera using a variety of methods, with an emphasis on using paleoclimatic proxies to understand the effects of surface uplift on Colombian climate. I have utilized organic geochemical proxies for paleotemperature (the MBT/CBT index) and for the isotopic composition of rainfall (hydrogen isotopes in leaf waxes) in order to quantify surface uplift in the Eastern Cordillera. I am also analyzing sedimentary provenance data and thermochronological data to determine the timing of uplift of a large area of exposed basement at the southern end of the Colombian Eastern Cordillera. tl;dr: Basin anaysis, organic geochemistry, low-temperature thermochronology

Chelsea Mackaman-Lofland (Supervisor)
My research focuses on the structural and tectonic evolution of the Argentine Andes. I will be using a combination of structural analysis and thermochronometry to provide modern age constraints for deformation and exhumation events in the Frontal and Pre-Cordillera. Ultimately, this work seeks to relate observed crustal shortening and related age constraints to the structures observed at depth (significantly, at the transition from normal to flat-slab subduction) in order to better characterize the mechanisms that drive Andean uplift and shortening in Mendoza and the surrounding provinces.

Sarah George (Supervisor)
Sarah is a first year masterís student focused on the interplay between regional tectonics and sedimentation. Specifically, she is working on elucidating the timing and mechanisms of shortening, exhumation, and basin evolution in the Andes of northern Peru. Methods include field work, U-Pb geochronology and (U-Th)/He thermochronology.
