In the geological sciences it has only recently been recognized how important the process of
impact cratering is on a planetary scale, where it is commonly the most important surface …

The number of newly discovered and confirmed impact structures on earth is growing
continuously. In this review paper, the main attributes of 198 confirmed impact structures and …

This article presents a current (as of September 2019) list of recommended ages for proven
terrestrial impact structures (n= 200) and deposits (n= 46) sourced from the primary …

The rise and diversification of shelled invertebrate life in the early Phanerozoic eon occurred
in two major stages. During the first stage (termed as the Cambrian explosion), a large …

Over the past few decades, it has become increasingly clear that the impact of interplanetary
bodies on other planetary bodies is one of the most ubiquitous and important geological …

Relict spinel grains (~ 25–250μm in diameter) from decomposed extraterrestrial material in
Archean to Recent sediments can be used to reconstruct variations in the flux of different …

Abstract The two Clearwater Lake impact structures (Québec, Canada) are generally
interpreted as a crater doublet formed by the impact of a binary asteroid. Here, arguments …

Although the~ 200 impact craters known on Earth represent only a small fraction of the
craters originally formed, the available data suggest an excess of craters by one order of …

Previous studies of mid-Ordovician limestone in Sweden have shown that over a
stratigraphic interval representing a few million years there is a two orders-of-magnitude …

Deciphering Earthʼs impact history before∼ 2 Ga relies heavily on the lunar record and
terrestrial spherule layers, which are distal ejecta from large impacts. This study focuses on …
