Deformation der karbonatischen Espanola-Formation im zentralen Teil der Sudbury-Impaktstruktur, Kanada
Steffes, Elisabeth;
; 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;; 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; (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 ... -
Microstructural evidence of impact-induced crystalplastic deformation and postshock annealing of quartz
; Spray, John G. (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
During impact, rocks at the surface and accessible depths encounter extreme conditions. The hydrostatic component of the shock wave-associatedstress, the so-called shock pressure, canreach several tens of GPa in the central ... -
The fate of sandstone during impact cratering: shock compaction, cataclastic flow, and granular fluidization
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
Impact of solid bodies is the most fundamental of all processes that have taken place on the terrestrial planets in our Solar system (Shoemaker 1977). On Earth, impact cratering was the dominant geologic process during the ... -
The importance of lithological heterogeneity of the Onaping Formation for understanding post-impact deformation of the Sudbury Impact Structure, Canada
Wittek, Andreas;; 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 ...
