Summary

[edit]
Description

Breccia is a rock typically consisting of rock fragments of various sizes and shapes that have been broken, tumbled and cemented together in sudden geologic event (e.g., a landslide, a flashflood or even an impact-cratering event). The prefix “mega” implies that the breccia consists of clasts, or rock fragments, that are typically bigger than a large house or a building.

Holden likely experienced extensive modification by running water, which is supported by observations of drainage and deposition into the crater from a large channel (Uzboi Valles) breaching crater’s southwest rim.

Image is less than 5 km (or 3 mi) across. For full images including scale bars, see the website link.
