There is one huge impact crater with a peak ring here, though: the Chicxulub crater at the edge of the Yucatán Peninsula, left by the dinosaur-killing impact at the end of the Cretaceous Period.

Here’s what happened in the impact crater the day it did in the dinos ... The first layer above the messed-up bedrock that formed the peak ring is made up of 40m of broken pieces of melted rock.

By analyzing cores from the peak ring of the impact crater, which were recovered when the site was drilled in 2016, a team from the Jackson School of Geosciences at the University of Texas at ...

Peak Ring: A circular, uplifted structure within a complex impact crater, formed during the modification stage through processes such as collapse and transient fluidisation.

Larger still are the so-called impact basins. An interior ring characterizes this crater form, which has three divisions of its own. Central peak basins, such as Compton, have a fragmented ring ...

The terraced floor, subtle central peak and underlying zone of highly deformed rock just below the depression are typical of large impact craters. U. Nicholson et al/ Science Advances 2022 ...

Impact Craters in Tyrrhena Terra The western part of the scene is dominated by a 35 kilometre-wide and approximately 1000 metre-deep impact crater with an extremely steep rim. The rim rises up to ...

martian impact crater with a central peak. Central peaks are common in large, fresh craters on both Mars and the Moon. This peak formed during the extremely high-energy impact cratering event.
