Veleda Muller
Assistant Professor of Geology and Neotectonics,
University of Alaska Fairbanks, CNSM/Geophysical Institute
I am a geologist focusing on Cordilleran tectonics and how the topography shapes and is shaped by climate-driven surface processes. I am interested in lithospheric processes forming fold-and-thrust belts, metamorphic complexes, and magmatic arcs, and in the surface response to these processes, for example river incision and glacial erosion. As those interactions are very dynamic and overlap different Earth sciences, I integrate field work, laboratory techniques focused on geo-thermochronology, and numerical modeling of geodynamic, thermodynamic, and surface processes.
​
I am passionated by both low- and high- temperature processes happening at the Earth's lithosphere. While low-temperature thermochronology gives us information about topography development, including tectonic deformation and erosion, high-temperature processes are resposible by ductile deformation, shear zones, and magmatism, key elements of subduction and collisional systems. One of my current goals is to bridge low and high temperature thermochronology and understand mountain building in the big picture.
​
I recently moved to Fairbanks, Alaska to start my position as Assistant Professor of Geology and Neotectonics. I will teach Structural Geology, Tectonics, Field Camp and develop new curricular courses. My plans are to work with the Cenozoic evolution of the Alaska and Brooks ranges, as well as keep working with the Andes and other subduction and collisional orogens.

My last first-author research article is published in Tectonics!
​
I am so glad to publish the first dataset of low-temperature thermochronology from the Fitz Roy and Torres del Paine plutonic complexes in southern Patagonia! In these iconic granite towers we quantify the effects of mantle dynamics and glacial erosion along the southern Patagonian Andes.
This article highlight that both asthenospheric and surface processes drive the formation of the topography and landscape of alpine valleys, but sometimes one force predominate over each other, and in few cases we are capable to differentiate them.

My research article about the effect of the slab window on glacial isostatic adjustment in southern Patagonia is published in Solid Earth!
​Using forward numerical modeling, we show that the thermal anomaly generated by the slab window in southern Patagonia is necessary to generate the present-day outstanding uplift rates of 10-40 mm/yr measured by GPS around the Southern Patagonian Icefields.
​We also show that this high magnitude of uplift is generated by both the Little Ice Age (400 years ago) and the Last Glacial Maximum (20000 years ago).

My article "Climatic control on the location of volcanic arcs" is published on Nature portfolio!
​
I used thermomechanical numerical modeling and a compilation of geochronology and thermochronology data to show that volcanic arcs can migrate in function of surface erosion. I used the Southern Andes and the North Cascade volcanic arcs as case studies, where the volcanism migrated towards the more eroded side of the orogenic belt. We propose this migration is entailed by the intensified orography associated with the westerlies winds.
​
This article shows for the first time that orography can force volanic arc migration, revealing one more link between climate and tectonics.

My first research article about the closure of the Rocas Verdes Basin is published in Tectonophysics!
​
This articles presents an integrated field-work, geochronology, petrology, and thermodynamic modeling study of the metamorphic rocks of the Magallanes fold-and-thrust belt, which were once the rocks of the backarc ocean-floored Rocas Verdes Basin in southern Patagonia.
​We show that this metavolcanic and sedimentary rocks experienced at least 20 km of tectonic burial in an accretionary wedge, and started to be exhumed in the Late Cretaceous. We show that this rocks record the passage from an extensional to a compressive tectonic setting in southern South America, when the Andes start to form and the southern tip of the continent start being bended.
