Detection and Quantification of Extraterrestrial Platinum Group Element Alloy Micronuggets from Archean Impactite Deposits by Low-Voltage Scanning Electron Microscopy/Energy-Dispersive X-ray Spectrometry.
Salge T, Mohr-Westheide T. Salge T, et al. Microsc Microanal. 2023 Dec 21;29(6):1837-1846. doi: 10.1093/micmic/ozad088. Microsc Microanal. 2023. PMID: 38073435
Rare, heterogeneously composed platinum group element alloy micronuggets (PGNs) occur in primitive meteorites, micrometeorites, and terrestrial impactite deposits. To gain insight into the nature of these phases, we developed a workflow for the characterization of PGNs usi …

A seismically induced onshore surge deposit at the KPg boundary, North Dakota.
DePalma RA, Smit J, Burnham DA, Kuiper K, Manning PL, Oleinik A, Larson P, Maurrasse FJ, Vellekoop J, Richards MA, Gurche L, Alvarez W. DePalma RA, et al. Proc Natl Acad Sci U S A. 2019 Apr 23;116(17):8190-8199. doi: 10.1073/pnas.1817407116. Epub 2019 Apr 1. Proc Natl Acad Sci U S A. 2019. PMID: 30936306 Free PMC article.
Here, we help to resolve this by describing a rapidly emplaced, high-energy onshore surge deposit from the terrestrial Hell Creek Formation in Montana. Associated ejecta and a cap of iridium-rich impactite reveal that its emplacement coincided with the Chicxulub event. Aci …

Oxygen isotope studies of ivory coast tektites and impactite glass from the bosumtwi crater, ghana.
Taylor HP Jr, Epstein S. Taylor HP Jr, et al. Science. 1966 Jul 8;153(3732):173-5. doi: 10.1126/science.153.3732.173. Science. 1966. PMID: 17831505
The Ivory Coast tektites are 2 to 5 per mil richer in oxygen-18 than other known tektites, and they are similar in oxygen-18 content to the impactite glass from the nearby Bosumtwi Crater. These data are compatible with a terrestrial origin for the Ivory Coast tektites....

El'gygytgyn impact crater, Chukotka, Arctic Russia: Impact cratering aspects of the 2009 ICDP drilling project.
Koeberl C, Pittarello L, Reimold WU, Raschke U, Brigham-Grette J, Melles M, Minyuk P, Spray J. Koeberl C, et al. Meteorit Planet Sci. 2013 Jul;48(7):1108-1129. doi: 10.1111/maps.12146. Epub 2013 Jul 2. Meteorit Planet Sci. 2013. PMID: 26074719 Free PMC article.
The uppermost impactite (316-328 mblb) contains lacustrine sediment mixed with impact-affected components. Over the whole length of the impactite core, the abundance of shock features decreases rapidly from the top to the bottom of the studied core section. ...

Preservation of biological markers in clasts within impact melt breccias from the Haughton impact structure, Devon Island.
Lindgren P, Parnell J, Bowden S, Taylor C, Osinski GR, Lee P. Lindgren P, et al. Astrobiology. 2009 May;9(4):391-400. doi: 10.1089/ast.2008.0270. Astrobiology. 2009. PMID: 19519214
This makes Haughton uniquely suitable for studies concerning the preservation of fossil biological markers following an impact event. Melt breccia is the most common impactite at Haughton. It is composed of clasts of the target, mainly carbonates, embedded in a fine ground …
