Rochechouart impact structure or Rochechouart astrobleme is an impact structure in France. Erosion has over the millions of years mostly destroyed its impact crater , the initial surface expression of the asteroid impact leaving highly deformed bedrock and fragments of the crater's floor as evidence of it.
Rochechouart is situated in the Rochechouart impact structure, an impact crater caused by an asteroid that crashed into the Earth's surface about 205 million years ago, [9] [10] in the Rhaetian period, shortly before the Triassic Jurassic boundary characterized by a massive extinction event in which 80% of the world's species were obliterated.

The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [3] and age, with some sources giving it as < 10 ka [2] [4] while the EID gives a broader < 100 ka. [3]
The following structures are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those for which it is difficult to collect evidence are generally known for some time before becoming listed.
The source of the Charente is in the department, in the commune of Chéronnac, near Rochechouart. [ 4 ] At the west end of the department is the Rochechouart impact structure , an impact crater caused by a meteorite that crashed into the Earth's surface over 200 million years ago; because of subsequent erosion , little sign of the crater is in ...
As the trend in the Earth Impact Database for about 26 confirmed craters younger than a million years old shows that almost all are less than two km (1.2 mi) in diameter (except the three km (1.9 mi) Agoudal and four km (2.5 mi) Rio Cuarto), the suggestion that two large craters, Mahuika (20 km (12 mi)) and Burckle (30 km (19 mi)), formed only ...
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth.
