Fig. 4: Sinuous and networked TAR development.
From: Networked configurations as an emergent property of transverse aeolian ridges on Mars
Secondary TARs (yellow lines) grow on the main crest (red). Regular growth proceeds from a to b. Reactivation of the primary ridge forms kinked sinuous primary ridges, directly from a to e. Rectangular networked TARs are formed by the growth of secondary ridges between primary ridges that do not experience kinking (a–c). Hexagonal-networked TARs can develop from rectangular networks that develop kinking (c, d) or from sinuous TARs (e–g). In this conceptualization, d and g are essentially equivalent forms with disparate origins. Over time, the hexagonal networks become more irregular (h) and the original primary/secondary ridge structure is lost.
