The sedimentary rock record is the primary repository of Earth history over the past four billion years. Major and trace element geochemistry and radiogenic isotopes are routinely used to investigate the sources of sediment (provenance) and the various processes that affect sediments throughout their history (e.g., weathering, sedimentary transport and recycling, diagenesis). The most sophisticated analytical methods that are available have been employed in sedimentary geochemistry and in many cases include grain by grain analyses of mineralogy, chemistry and isotopic characteristics. In turn, this information has been used to address many important issues, such as tectonic associations, environments of deposition, paleoclimates, paleohydrology, and crust/mantle evolution. Photographic, spectroscopic and geochemical results, returned from the surface of Mars over many years and many missions, have increasingly pointed towards a wide variety of sedimentary processes playing a dominant role in shaping the Martian surface. Accordingly, there is great potential for applying the knowledge that has been learned from studying terrestrial sedimentary rocks towards evaluating Martian geological history. Chemical and mineralogical analyses from the Martian surface, especially those from the Viking, Pathfinder, and Mars 2001/2003 missions, coupled with greater understanding of basaltic sedimentation on the Earth should provide the sedimentological framework within which to study the chemistry and mineralogy of returned Martian samples.
