Marine Impacts and Environmental Consequences – Drilling of the Mjølnir Structure, the Barents Sea
Autor: Takafumi Matsui, Frank T. Kyte, Henning Dypvik, Alex Deutsch, Philippe Claeys, Morten Smelror
Publikováno v: Scientific Drilling, Iss 6, Pp 55-57 (2008)
In September 2007, thirty-three scientists attended an international workshop in Longyearbyen (Svalbard, Norway) to discuss impacts of extraterrestrial bodies into marine environment and to prepare for the drilling of the 142-Ma-old Mjølnir impact s

Widespread elevated iridium in Upper Triassic–Lower Jurassic strata of the Newark Supergroup: implications for use as an extinction marker
Autor: Lawrence H. Tanner, John H. Puffer, Frank T. Kyte
Publikováno v: Scientific Reports, Vol 10, Iss 1, Pp 1-10 (2020)
Scientific Reports
Anomalous levels of iridium in sedimentary strata are associated with mass extinction events caused by impact events. In the case of the end-Triassic extinction event, the anomalies as well as the extinctions are linked to the eruption of the Central

Distribution of iridium and associated geochemistry across the Triassic–Jurassic boundary in sections at Kuhjoch and Kendlbach, Northern Calcareous Alps, Austria
Autor: Frank T. Kyte, Sylvain Richoz, Lawrence H. Tanner, Leopold Krystyn
Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 449:13-26
Samples from strata spanning the Triassic–Jurassic boundary at the GSSP at Kuhjoch and at Kendlbachgraben were studied by NAA, XRF and combustion analysis to determine Ir levels and associated geochemistry. The results are compared to previously de

The End-Triassic Extinction Event: The case for an extraterrestrial rather than terrestrial cause
Autor: Jan Smit, Max Jansen, Frank T. Kyte, Sietze Jan De Graaff
Publikováno v: Vrije Universiteit Brussel
Most theories about the end-Triassic extinction (ETE) event involve a relationship with the early Jurassic central Atlantic magmatic province (CAMP) LIP. We report new evidence from the Čanj section in Montenegro that indicates an impact event at th

Recently discovered 3.42-3.23 Ga impact layers, Barberton Belt, South Africa: 3.8 Ga detrital zircons, Archean impact history, and tectonic implications
Autor: Frank T. Kyte, Gary R. Byerly, Donald R. Lowe
Publikováno v: Geology. 42:747-750
The Barberton greenstone belt (BGB) includes eight known layers containing spherical particles (spherules) that condensed from rock vapor clouds formed by the impact of large meteorites or asteroids 3.47–3.23 Ga. Previous studies have inferred that

Chromium-isotopes in Late Eocene impact spherules indicate a likely asteroid belt provenance
Autor: Jana Hanova, Alex Shukolyukov, Guenter W. Lugmair, Alan R. Hildebrand, Frank T. Kyte
Publikováno v: Earth and Planetary Science Letters. 302:279-286
Spherules and magnetic fractions extracted from two late Eocene impact deposits — Massignano, Italy and Ocean Drilling Program Hole 709C, western Indian Ocean, have anomalous concentrations of Ir, and high concentrations of Cr, Ni, Co, and Fe. An e

Multiple Ir anomalies in uppermost Triassic to Jurassic-age strata of the Blomidon Formation, Fundy basin, eastern Canada
Autor: Frank T. Kyte, Ann E. Walker, Lawrence H. Tanner
Publikováno v: Earth and Planetary Science Letters. 274:103-111
article i nfo A detailed profile of Ir concentrations in continental strata of the Blomidon Formation ostensibly spanning the Triassic-Jurassic boundary confirms the existence of multiple anomalies, with a peak Ir concentration of 450 pg/g. The total
