The surface materials on Mars provide important constraints on the nature, timing and duration of surface process and can be used to study the history of erosion, transport and deposition of sediments and the relationships between surface sediments and bedrock. Perhaps most importantly, they may contain a record of changes in environmental conditions. These materials are readily accessible to a variety of remote-sensing observations, as well as direct, in situ observations from landed spacecraft. Viking Orbiter color data indicate the presence of three major surface materials: low-inertia, bright-red material that is presumably dust; high-inertia, dark-grey material interpreted to be lithic material mixed with palagonite-like dust; and moderate-inertia, dark-red material that is rough at subpixel scales and interpreted to be indurated. -from Authors
