Martian Megabreccia

April 16, 2013
"Megabreccia" is a term we use to describe jumbled, fragmented blocks of rock larger than 1 meter across, in a matrix of finer-grained materials. It's the result of energetic processes, typically from an impact event.

This image was acquired by HiRISE only in the narrow color strip, as a ridealong with a CRISM target, since HiRISE had previously imaged this location.
