Abstract Lake El'gygytgyn in Far East Russia is a 3.6 Myr old impact crater lake. Located in
an area that has never been affected by Cenozoic glaciations nor desiccation, the unique …

Tektites are mm to cm sized glassy objects generated through high-energy meteoroid
impacts on the surface of the Earth under high temperature and pressure, and reducing …

The circa 14 km diameter Pantasma circular structure in Oligocene volcanic rocks in
Nicaragua is here studied for the first time to understand its origin. Geomorphology, field …

The El'gygytgyn impact structure in Chukutka, Arctic Russia, is the only impact crater
currently known on Earth that was formed in mostly acid volcanic rocks (mainly of rhyolitic …

Internal structure and element chemistry including contents of highly siderophile elements
(HSE) and Os isotope ratios have been studied in target rocks and several groups of impact …

Non-mass dependent chromium isotopic signatures have been successfully used to
determine the presence and identification of extra-terrestrial materials in terrestrial impact …

The Dhala structure in north‐central India is a confirmed complex impact structure of
Paleoproterozoic age. The presence of an extraterrestrial component in impactites from the …

The existence of mass‐independent chromium isotope variability of nucleosynthetic origin in
meteorites and their components provides a means to investigate potential genetic …

The Lonar crater is a~ 0.57‐Myr‐old impact structure located in the Deccan Traps of the
Indian peninsula. It probably represents the best‐preserved impact structure hosted in …

The late addition of extra-terrestrial material may represent an important source of Earth's
volatiles. The composition of impactors can be reconstructed using 54 Cr abundances in …
