The terrestrial record of late heavy bombardment
DR Lowe, GR Byerly - New Astronomy Reviews, 2018 - Elsevier
Until recently, the known impact record of the early Solar System lay exclusively on the
surfaces of the Moon, Mars, and other bodies where it has not been erased by later …

Early bombardment of the moon: Connecting the lunar crater record to the terrestrial planet formation
The lunar crater record features∼ 50 basins. The radiometric dating of Apollo samples
indicates that the Imbrium basin formed relatively late—from the planet formation …

Delayed and variable late Archaean atmospheric oxidation due to high collision rates on Earth
Frequent violent collisions of impactors from space punctuated the geological and
atmospheric evolution of early Earth. It is generally accepted that the most massive collisions …

Ruthenium isotopes show the Chicxulub impactor was a carbonaceous-type asteroid
An impact at Chicxulub, Mexico, occurred 66 million years ago, producing a global
stratigraphic layer that marks the boundary between the Cretaceous and Paleogene …

Provenance and tectonic implications of the 3.28–3.23 Ga Fig Tree Group, central Barberton greenstone belt, South Africa
Sedimentary rocks provide a valuable record of non-uniformitarian Paleoarchean tectonic
processes. The rocks of the 3.28–3.23 Ga Mapepe Formation mark the initiation of …

Identification of Earth's late accretion by large impactors through mass independent Cr isotopes
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 …
