Briault is an impact crater in the Mare Tyrrhenum quadrangle of Mars, located at 10.2°S latitude and 270.4°W longitude. It is 96.6 kilometers in diameter and was named after P. Briault, and the name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN).[1] The dark areas seen in the images are dunes; the curved dunes are called barchans.
