Distinguishing between the two drivers is often challenging, as many modern flat slabs spatially coincide with subducting buoyant ridges. The Peruvian flat slab is the largest region of active flat slab subduction on Earth, spanning over 1300 km of the subducting Nazca plate along the western margin of South America. The flat slab is associated with two seafloor ridges: the Nazca Ridge at the southern terminus and the fully subducted Inca Plateau in the north. These aseismic ridges are spatially confined with respect to the flat slab, allowing assessment of the relative roles of aseismic ridge interactions and flat slab subduction in driving upper plate exhumation. We present: (1) a regional compilation of geochronologic ages of Andean igneous rocks, which track the spatio-temporal evolution of Neogene magmatic arc cessation and hence slab flattening; (2) calculated geomorphic indices, which document landscape perturbations and climatic or lithologic changes, (3) a summary of erosion rates from river catchments on the western Andean slope, and; (4) a regional synthesis of thermochronologic ages that reflect the timing and magnitude of upper crustal cooling. Thermochronometric cooling ages systematically track the progressive passage of the Nazca Ridge, suggesting that the buoyant ridge focused exhumation in the overriding plate. Geomorphic indices demonstrate enhanced topography and steeper channels closer to the position of the subducted ridge. The spatial progression of basement block uplifts in Peru also coincides with the timing of ridge passage. In hinterland regions, >2 km of exhumation occurred since ca. 15 Ma above the Peruvian flat slab. For individual locations within the orogen, active rock uplift declines after ridge passage, suggesting that increased coupling is not maintained across the entirety of the flat slab. We argue that above broad zones of flat slab subduction, focused areas of aseismic ridge subduction concentrate upper-plate exhumation and uplift. These observations may be relevant to other flat slab systems, which exhibit a broad zone of arc shutoff with corridors of focused exhumation.}, journal={EARTH AND PLANETARY SCIENCE LETTERS}, publisher={Elsevier BV}, author={George, Sarah W.

We employ a finite-element method to model the 3D flexural deformation of the lithosphere beneath the Pyrenean orogen since the onset of convergence in the Late Cretaceous. Using subsurface and structural data, we describe the evolving geometry of both the northern Aquitaine and southern Ebro foreland basins at the Paleocene (early orogenic phase), the end- and mid-Eocene (peak orogenic phase), the Oligocene (late orogenic phase), and the present (post-orogenic phase). The flexural modeling provides insight into how both the rigidity of the lithosphere and the paleotopographic load have varied over the course of orogenesis to shape the basin geometry. Employing a 3D continuous-plate model, we find that the overriding European plate has slightly higher rigidity than the underthrusting Iberian plate. The best-fit model results for the modern setting produce a root-mean-square error (RMSE) of 458 m using effective elastic thickness (Te) values of 23 and 16 km for the European and Iberian plates, respectively. We also test a broken-plate model, which produces a similar RMSE but predicts higher Te (32 km for the European plate and 26 km for the Iberian plate). The broken-plate model results indicate minimal vertical plate-boundary forces are necessary to reproduce the observed basin geometry. Flexural modeling results suggest that the topographic load doubled from the Paleocene to the Oligocene, and achieved modern topography by the end of the Eocene. The topography remained relatively stable throughout the Oligocene and Neogene, with only limited growth and decay. These results have implications for surface processes and foreland-basin development of the Pyrenean Orogen, tectonic inheritance, and the geodynamic evolution of Western Europe.}, journal={Earth and Planetary Science Letters}, publisher={Elsevier BV}, author={Curry, Magdalena Ellis and Beek, Peter and Huismans, Ritske S. and Wolf, Sebastian G. and Muñoz, Josep-Anton}, year={2019}, month={Jun}, pages={26–37} } @article{curry_peel_hudec_norton_2018, title={Extensional models for the development of passive‐margin salt basins, with application to the Gulf of Mexico}, url={https://doi.org/10.1111/bre.12299}, DOI={10.1111/bre.12299}, abstractNote={Abstract}, journal={Basin Research}, author={Curry, Magdalena A.

Here we examine the links between fault kinematics, emergent topography, and environmental factors on a global data set of active fault-driven mountain ranges (n = 41). Using simple regressions between tectonic, climatic, and topographic variables, we explore the controls on fault-driven landscape development at the range scale. For each fault in our Google Earth accessible database, we compiled (1) topographic metrics from a 30-m digital elevation model including along-strike changes in elevation and relief, fault length, and tip zone length (the along-strike distance from fault tip to where the associated relief stops increasing) and gradient; (2) long-term (10 4–6 yr) tectonic variables including fault slip rate, displacement rate, displacement, and age; (3) climatic variables including annual precipitation; and (4) rock type from geologic maps. Our results show that all mountain ranges reach a uniform value of relief within some distance from their tips and the length scale of this relief growth correlates with long-term vertical displacement rate (R = 0.55) and slip rate (R = 0.51). We apply a well-established framework for fault growth as the tectonic boundary condition to estimate the time required to achieve this uniform relief (∼10 4–6 yr) and suggest that this threshold time indicates regional tectonomorphic equilibrium. Strong correlations between annual precipitation and deformation rates (R > 0.60), and between lithologic strength and mountain relief (R > 0.70), allude to other principal forces affecting emergent landscape form that are often ignored. Our findings demonstrate that fault-driven topography always saturates in relief, suggest there are quantifiable fault-kinematic controls on landscape form, and hint that landscape relief patterns may, in turn, be used to estimate rates of faulting.}, number={4}, journal={Geosphere}, author={Ellis, Magdalena A. and Barnes, Jason B.}, year={2015}, pages={1008–1023} } @article{ellis_barnes_colgan_2015, title={Geomorphic evidence for enhanced Pliocene-Quaternary faulting in the northwestern Basin and Range}, volume={7}, url={http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcAuth=ORCID&SrcApp=OrcidOrg&DestLinkType=FullRecord&DestApp=WOS_CPL&KeyUT=WOS:000351916600006&KeyUID=WOS:000351916600006}, DOI={10.1130/L401.1}, abstractNote={Mountains in the U.S. Basin and Range Province are similar in form, yet they have different histories of deformation and uplift. Unfortunately, chronicling fault slip with techniques like thermochronology and geodetics can still leave sizable, yet potentially important gaps at Pliocene–Quaternary (∼105–106 yr) time scales. Here, we combine existing geochronology with new geomorphic observations and approaches to investigate the Miocene to Quaternary slip history of active normal faults that are exhuming three footwall ranges in northwestern Nevada: the Pine Forest Range, the Jackson Mountains, and the Santa Rosa Range. We use the National Elevation Dataset (10 m) digital elevation model (DEM) to measure bedrock river profiles and hillslope gradients from these ranges. We observe a prominent suite of channel convexities (knickpoints) that segment the channels into upper reaches with low steepness (mean k sn = ∼182; θref = 0.51) and lower, fault-proximal reaches with high steepness (mean k sn = ∼361), with a concomitant increase in hillslope angles of ∼6°–9°. Geologic maps and field-based proxies for rock strength allow us to rule out static causes for the knickpoints and interpret them as transient features triggered by a drop in base level that created ∼20% of the existing relief (∼220 m of ∼1050 m total). We then constrain the timing of base-level change using paleochannel profile reconstructions, catchment-scale volumetric erosion fluxes, and a stream-power–based knickpoint celerity (migration) model. Low-temperature thermochronology data show that faulting began at ca. 11–12 Ma, yet our results estimate knickpoint initiation began in the last 5 Ma and possibly as recently as 0.1 Ma with reasonable migration rates of 0.5–2 mm/yr. We interpret the collective results to be evidence for enhanced Pliocene–Quaternary fault slip that may be related to tectonic reorganization in the American West, although we cannot rule out climate as a contributing mechanism. We propose that similar studies, which remain remarkably rare across the region, be used to further test how robust this Plio–Quaternary landscape signal may be throughout the Great Basin.}, number={1}, journal={Lithosphere}, author={Ellis, Magdalena A. and Barnes, Jason B. and Colgan, Joseph P.}, year={2015}, pages={59–72} } @article{ellis_laubach_eichhubl_olson_hargrove_2012, title={Fracture development and diagenesis of Torridon Group Applecross Formation, near An Teallach, NW Scotland: millennia of brittle deformation resilience?}, volume={169}, url={http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcAuth=ORCID&SrcApp=OrcidOrg&DestLinkType=FullRecord&DestApp=WOS_CPL&KeyUT=WOS:000308669800005&KeyUID=WOS:000308669800005}, DOI={10.1144/0016-76492011-086}, abstractNote={The Late Proterozoic Torridon Group Applecross Formation in the foreland of the Moine Thrust Belt, NW Scotland, contains deformation bands, three fracture sets (from oldest to youngest A, B, and L) defined by orientation, crosscutting relations, and progressively less quartz cement in younger sets, and joints. Set A crosscuts deformation bands and strikes north–south. Set B has trimodal orientation defining three linked subsets that formed concurrently. Set L strike ranges from NE–SW to ENE–WSW, in parent crack–wing crack arrays that formed progressively; these are more abundant near small-displacement, oblique-slip faults that offset the overlying Cambrian Eriboll Formation and the Moine Thrust Belt. Applecross sandstones have low fracture abundance, possibly a consequence of low elastic moduli (Young’s modulus 2.3–17.0 GPa, most values <6.9 GPa) and moderate to high subcritical crack index (45–78), resulting from compacted soft lithic grains and clay-mineral cements. Low abundance contradicts models that postulate persistent incipient failure by subsurface fracture. The fracture sequence resembles that found in the overlying Cambrian Eriboll Formation quartzarenites, implying that no widespread late Proterozoic fracture sets exist in this part of the Applecross Formation, an uneventful record for a rock profoundly resistant to brittle deformation.}, number={3}, journal={Journal of the Geological Society}, author={Ellis, Magdalena A. and Laubach, S.
