Abstract
On Earth, vegetation is the most common provider of the fundamental control element determining scroll-bar and meander formation in fluvial channels. Studies of ancient terrestrial alluvium have demonstrat-ed that there is little evidence for heterolithic meander-ing fluvial systems in strata deposited prior to the evo-lution of land plants, indirectly demonstrating that the bank stability, bed roughness, and channel-corralling necessary to promote meandering are, on Earth, most often provided by vegetation. How-ever, lateral accretion and meander belts on Mars (Figs. 1 and 2), and occasionally within Precambrian alluvium, attest to the existence of alternative medi-ators for the prevention of continuous reworking of meanders.
