U‐Pb dating of zircon and monazite from the uplifted Variscan crystalline basement of the Ries impact crater
Impact crater central peaks and peak ring complexes are important exploration targets for future missions to other planetary bodies, because they provide access to material uplifted from lower
High-resolution EBSD and SIMS U–Pb geochronology of zircon, titanite, and apatite: insights from the Lac La Moinerie impact structure, Canada
High-resolution electron backscattered diffraction (EBSD) and correlated in situ secondary ion mass spectrometry (SIMS) U–Pb geochronology have been conducted on impact-metamorphosed zircon,

Morokweng, South Africa: A large impact structure of Jurassic-Cretaceous boundary age
Geophysical, petrographical, and geochemical data indicate the presence of a large impact structure in the area around Morokweng, Northwest Province, South Africa, possibly up to 340 km in diameter.
Differentiated impact melt sheets may be a potential source of Hadean detrital zircon [REPLY]
Constraining the origin and history of very ancient detrital zircons has unique potential for furthering our knowledge of Earth’s very early crust and Hadean geodynamics. Previous applications of the
Cubic zirconia in >2370 °C impact melt records Earth's hottest crust
Impact melt sheet zircons and their implications for the Hadean crust
Impacts may have been important mechanisms of crustal redistribution and differentiation, particularly during intense postaccretionary bombardment between 4.5 Ga and 3.9 Ga ago. Evidence of crustal
The dimensions of the Chicxulub impact crater and impact melt sheet
The Chicxulub impact crater, which is the principal source of impact debris in Cretaceous-Tertiary boundary sediments, is currently buried by a ∼1 km thick sequence of carbonate sediments. Because
