Cenozoic Exhumation and Deformation of the Intermontane Pastos Chicos Basin in the Southern Central Andes: Implications for the Tectonic Evolution of the Andean Plateau (Puna) and the Eastern Cordillera Between 23° and 24°S, NW Argentina
Pingel, Heiko; Deeken, Anke; Coutand, Isabelle; Alonso, Ricardo N.; Riller, Ulrich; Sobel, Edward R.; Cottle, John M.; Strecker, Manfred R. (Tectonics, 2023-02-03)The Andean Plateau of north‐western Argentina (Puna) at a mean elevation of ca. 4.2 km constitutes the southern continuation of the Altiplano; it is a compressional basin‐and‐range province comprising fault‐bounded, ... -
Deformation der karbonatischen Espanola-Formation im zentralen Teil der Sudbury-Impaktstruktur, Kanada
Steffes, Elisabeth; Riller, Ulrich; Doman, Daniel (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Archaische Granitoide und paläoproterozoische Metasedimente der Huronian Supergroup werden von dem schüsselförmigen und partiell erodierten 1.85 Ga alten Impaktschmelzkomplex der Sudbury-Impaktstruktur überlagert. Huronische ... -
Deformation mechanisms in the eastern Sudbury Igneous Complex, Canada: Evidence for meteorite impact into an active orogen
Doman, Daniel; Riller, Ulrich; Hofmann, Kai (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The 1.85 Ga Sudbury Igneous Complex (SIC) in central Ontario is now widely considered to be the erosional remnant of a deformed paleo-horizontal impact melt sheet, about 2.5 km in thickness. Deformed impact melt breccias ... -
Deformation of the Onaping Formation in the NE-lobe of the Sudbury Igneous Complex, Canada: Evidence for fold adjustment flow in the core of a km-scale fold
Klimczak, Christian; Riller, Ulrich (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The synformal geometry of the 1.85Ga Sudbury Igneous Complex (SIC), an impact melt sheet resulting from largemagnitude meteorite impact, attests to post-impact deformation. However, in contrast to the overlying Onaping ... -
From Proterozoic tectonics to Quaternary climate variability: Earth system science studies in Latin America
Riller, Ulrich; Giambiagi, Laura; Strecker, Manfred R. (International Journal of Earth Sciences, 2021-08-12)This paper is the editoral of a Special Issue of International Journal of Earth Sciences, that features a selection of scientific contributions presented at the 25th Latin-American Colloquium. According to the Earth System ... -
Identification of uppercrustal discontinuities using dip curvature analysis of isostatic residual gravity: examples from the central Andes
Riller, Ulrich; Götze, Hans-Joachim; Schmidt, Sabine; Trumbull, Robert; Hongn, Fernado; Petrinovic, Ivan (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Structural analysts are often faced with the problem of identifying prominent structural discontinuities covered by post-tectonic sedimentary or volcanic rocks. Gravity fields are often used to delineate the trace of buried ... -
Impact-Induced Porosity and Microfracturing at the Chicxulub Impact Structure
Rae, Auriol S. P.; Collins, Gareth S.; Morgan, Joanna V.; Salge, Tobias; Christeson, Gail L.; Leung, Jody; Lofi, Johanna; Gulick, Sean P. S.; Poelchau, Michael; Riller, Ulrich; Gebhardt, Catalina; Grieve, Richard A. F.; Osinski, Gordon R.; IODP- and ICDP Expedition 364 Scientists (Journal of Geophysical Research: Planets, 2019)Porosity and its distribution in impact craters has an important effect on the petrophysical properties of impactites: seismic wave speeds and reflectivity, rock permeability, strength, and density. These properties are ... -
Kinematic partitioning in the Southern Andes (39° S–46° S) inferred from lineament analysis and reassessment of exhumation rates
Göllner, Paul Leon; Eisermann, Jan Oliver; Balbis, Catalina; Petrinovic, Ivan A.; Riller, Ulrich (International Journal of Earth Sciences, 2021-07-08)The Southern Andes are often viewed as a classic example for kinematic partitioning of oblique plate convergence into components of continental margin-parallel strike-slip and transverse shortening. In this regard, the ... -
Ocean resurge-induced impact melt dynamics on the peak-ring of the Chicxulub impact structure, Mexico
Schulte, Felix M.; Wittmann, Axel; Jung, Stefan; Morgan, Joanna V.; Gulick, Sean P. S.; Kring, David A.; Grieve, Richard A. F.; Osinski, Gordon R.; Riller, Ulrich (International Journal of Earth Sciences, 2021-03-18)Core from Hole M0077 from IODP/ICDP Expedition 364 provides unprecedented evidence for the physical processes in effect during the interaction of impact melt with rock-debris-laden seawater, following a large meteorite ... -
Origin of Central Andean collapse calderas
Regional strains in tectonically active volcanic provinces may have a profound influence on the mode of collapse caldera formation. Conversely, the deformation pattern, more specifically, the symmetry of plan-view strain ... -
Orogen-scale transpression accounts for GPS velocities and kinematic partitioning in the Southern Andes
Eisermann, Jan Oliver; Göllner, Paul Leon; Riller, Ulrich (Communications Earth & Environment, 2021-08-19)The Southern Andes are regarded as a typical subduction orogen formed by oblique plate convergence. However, there is considerable uncertainty as to how deformation is kinematically partitioned in the upper plate. Here we ... -
The importance of lithological heterogeneity of the Onaping Formation for understanding post-impact deformation of the Sudbury Impact Structure, Canada
Wittek, Andreas; Riller, Ulrich; Hecht, Lutz (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)The suevitic Onaping Formation overlies the layered Main Mass of the 1.85Ga Sudbury Igneous Complex (SIC) of the Sudbury Impact Structure, Ontario. The Formation consists of four Members, namely from top to bottom, the ...
