Becquerel Bands

January 4, 2013
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows alternating light- and dark-toned bands--layers of sedimentary rock exposed by erosion in Becquerel Crater. Becquerel is located in western Arabia Terra near 4.1°N, 111.5°W, and might have once been the site of a lake. A few straight, narrow fault lines can be seen in the image; they cut the rock in trends that run from upper right toward lower left (northeast-southwest). This picture covers an area about 1.5 km (0.9 mi) wide and is illuminated by sunlight from the left. MGS MOC Release No. MOC2-987, 30 January 2005
