Estimates of yet-to-find impact crater population on Earth

Abstract: One hundred and seventy-six craters on Earth are currently accepted as resulting from bolide impact; this list is growing at a rate of approximately two craters per year because of new discoveries and revised interpretations. Here we take the subset of craters most relevant to sedimentary basin exploration and utilization (Phanerozoic kilometre-scale craters) and tackle the question of how many remain to be found in Phanerozoic strata on Earth. A surprising range in predictions of crater numbers is obtained fr… Show more

“…Those craters larger than 4 km have more complex morphologies, largely due to gravity‐driven collapse. There are currently 190 confirmed terrestrial impact structures, ranging in size from <1 km to >100 km in diameter (Spray ), representing a fraction of the total number anticipated in the geological record (Stewart ).…”

“…Since the 1960s, the number of established terrestrial meteorite structures has increased steadily at a rate of a few new structures per year (Grieve, 1998), chiefly because the recognition of these shock-metamorphic features (generally shatter cones and PDFs in quartz) has made it possible to identify impact structures that are old, poorly exposed, deeply eroded, buried, or even subjected to post-impact metamorphism. At present, more than 190 preserved impact structures have been definitely identified (Earth Impact Database, 2016), and model calculations suggest that at least several hundred preserved impact structures remain to be discovered on the land areas of the earth (Trefil and Raup, 1990;Grieve, 1991;Stewart, 2011;Hergarten and Kenkmann, 2015).…”

“…The distribution of the presently identified impact craters on Earth, and also the cratering history of the inner solar system bodies (Strom et al. ) indicate that more impact craters should be preserved at Earth's surface (Stewart ). Besides possibly buried impact structures, Hergarten and Kenkmann () estimated the possible number of preserved impact craters on the Earth's surface, and their method yielded about 13–20 additional impact craters with diameters ranging from a few hundred meters to about 6 km that should be exposed at the surface within the borders of China.…”
