- W2770014967 abstract "The Late Triassic (Carnian to Rhaetian Stages: ca. 237–201 Ma) has a long history of geological research, although controversy remains over the precise definition of key sub-unit boundaries, including those defining the three constituent stages. Within this context, at least five terrestrial bolide impact structures ranging from 9 to 85 km in diameter have been identified at present-day northern latitudes, the proximal remnant crater aspects of which have been studied in increasing detail over the last few decades. The more elusive distal sedimentary expressions of these multi-sized hypervelocity events remain largely unknown, although if preserved, identified and interpreted correctly, may (as precisely dateable event horizons) help to address certain existing stratigraphic uncertainties, particularly pertaining to the (longest) Norian Stage. Detailed absolute age-dating using a range of radioisotopic methods (e.g. U-Pb and 40Ar/39Ar) currently indicates that at least three of the confirmed Late Triassic impact craters formed prior to commencement of the major Rhaetian Central Atlantic Magmatic Province (CAMP) volcanic episode by several million years. Impact research efforts to date have focused mainly on describing and process modeling the relatively well-preserved largest impact structure, Manicouagan (215.5 Ma; 85 km diameter) located in northeastern Quebec, Canada and, to a lesser extent, the Saint Martin (227.8 Ma; 40 km) and Rochechouart (ca. 207–201 Ma; ca. 23–50 km) structures in central Manitoba, Canada and west-central France respectively. The smaller, subsurface Red Wing structure (ca. 200 Ma; 9 km diameter, ca. 2.5 km burial depth) located in South Dakota, USA, also has attracted significant economic interest. Unlike the well-documented End Cretaceous Chicxulub impact (66 Ma; ca. 180 Km), attempts to establish a globally significant causal extinction connection between the larger impacts (e.g. Manicouagan and Rochechouart) and Late Triassic marine and terrestrial bioevents, culminating with the ‘End Triassic Extinction’ (ETE), have essentially proved unsuccessful." @default.
