    Tectonic development of the Samail ophiolite: High-precision U-Pb zircon geochronology and Sm-Nd isotopic constraints on crustal growth and emplacement by Rioux, Matthew, Kelemen, Peter B., Gordon, Stacia, Miller, Robert, Bowring, Samuel A., Dudas, Francis O.

    Published 2014
    “…New high-precision single grain U-Pb zircon geochronology and whole rock Nd isotopic data provide insight into the magmatic and tectonic development of the Samail ophiolite. The analyzed rocks can be broadly divided into two groups based on their structural position, dates, and isotopic composition: an older group related to on-axis magmatism and a younger group of post-ridge dikes, sills, and stocks. …”

    Surface expression of eastern Mediterranean slab dynamics: Neogene topographic and structural evolution of the southwest margin of the Central Anatolian Plateau, Turkey by Schildgen, T. F., Cosentino, D., Caruso, A., Buchwaldt, Robert, Yildirim, C., Bowring, Samuel A., Rojay, B., Echtler, H., Strecker, M. R.

    Published 2012
    “…Broad similarities in the change in the tectonic stress regime (after 8 Ma) and the onset of surface uplift (after 7 Ma) imply that deep-seated process(es) caused post-7 Ma uplift. …”

    Protracted timescales of lower crustal growth at the fast-spreading East Pacific Rise by Rioux, Matthew, Johan Lissenberg, C., McLean, Noah Morgan, Bowring, Samuel A., MacLeod, Christopher J., Hellebrand, Eric, Shimizu, Nobumichi

    Published 2014
    “…The formation of oceanic crust at mid-ocean ridges is a fundamental component of plate tectonics. A large fraction of the new crust is created when magmas in the lower crust cool to form gabbroic rocks. …”

    The origin of graben and ridges in Rachmaninoff, Raditladi, and Mozart basins, Mercury by Blair, David M., Freed, Andrew M., Byrne, Paul K., Klimczak, Christian, Prockter, Louise M., Ernst, Carolyn M., Solomon, Sean C., Melosh, H. Jay, Zuber, Maria

    Published 2014
    “…The Rachmaninoff, Raditladi, and Mozart peak-ring impact basins on Mercury display a distinctive pattern of tectonic features consisting of a central zone that is either devoid of tectonic landforms or contains small ridges, a medial annulus of prominent and predominantly circumferentially oriented graben, and a distal zone displaying graben that occur in a mix of orientations and that are less evident toward the peak ring. …”

    Crystallization depth beneath an oceanic detachment fault (ODP Hole 923A, Mid-Atlantic Ridge) by Lissenberg, C. Johan, Rioux, Matthew, MacLeod, Christopher J., Shimizu, Nobumichi, Bowring, Samuel A.

    Published 2017
    “…We here present U-Pb zircon dates for these gabbros and associated diorite veins which, when combined with a tectonic reconstruction of the area, allow us to calculate the depths at which the melts crystallized. …”

    The thermal evolution of an Earth with strong subduction zones by Conrad, Clinton P., Hager, Bradford H

    Published 2017
    “…It is commonly supposed that plate tectonic rates are controlled by the temperature-dependent viscosity of Earth's deep interior. …”

    Radial anisotropy in the crust of SE Tibet and SW China from ambient noise interferometry by Huang, Hui, Yao, Huajian, van der Hilst, Robert D

    Published 2012
    “…We use Rayleigh and Love wave Green's functions estimated from ambient seismic noise to study crustal structure and radial anisotropy in the tectonically complex and seismically active region west of the Sichuan Basin and around the Eastern Himalaya Syntaxis. …”

    Low-latitude arc–continent collision as a driver for global cooling by Macdonald, Francis A., Jagoutz, Oliver E, Royden, Leigh H

    Published 2016
    “…New constraints on the tectonic evolution of the Neo-Tethys Ocean indicate that at ∼90–70 Ma and at ∼50–40 Ma, vast quantities of mafic and ultramafic rocks were emplaced at low latitude onto continental crust within the tropical humid belt. …”

    Colloquium: Failure of molecules, bones, and the Earth itself by Keten, Sinan, Buehler, Markus J

    Published 2010
    “…Based on case studies, mechanisms of failure of a wide range of materials are discussed, ranging from tectonic plates to rupture of single molecules, and an explanation on how atomistic simulation can be used to complement experimental studies and theory to provide a novel viewpoint in the analysis of complex systems is provided. …”

    Re-Os geochronology and coupled Os-Sr isotope constraints on the Sturtian snowball Earth by Dudas, Francis O., Hallman, Christian, Rooney, Alan D., Macdonald, Francis A., Strauss, Justin V., Selby, David

    Published 2014
    “…Although the initiation mechanism of these Neoproterozoic Snowball Earth events has remained a mystery, the broad synchronicity of rifting of the supercontinent Rodinia, the emplacement of large igneous provinces at low latitude, and the onset of the Sturtian glaciation has suggested a tectonic forcing. We present unique Re-Os geochronology and high-resolution Os and Sr isotope profiles bracketing Sturtian-age glacial deposits of the Rapitan Group in northwest Canada. …”

    Solutions of the stream power equation and application to the evolution of river longitudinal profiles by Perron, J. Taylor, Royden, Leigh H

    Published 2014
    “…At migrating knickpoints, slope patches and the information they carry are lost, a phenomenon that fundamentally limits the potential for reconstructing tectonic histories from bedrock river profiles. Stationary knickpoints, which can arise from spatially varying uplift rates, differ from migrating knickpoints in that slope patches and the information they carry are not lost. …”
