Definition

Zones of concentration of positive topographic linear structures (Kryuchkov 1990). Geologically, they are linear zones of concentrated deformation hundreds of kilometers long and tens of kilometers wide (Fernández et al. 2010).

Description, Units, and Interpretation

Deformation belts are complex tectonic units including ridges, extensional fractures, and strike-slip fractures.

    Ridges or Ridge belts (see Ridged Plains) composed of parallel ridges, each a few hundred meters in elevation. Typical fold spacings are 5–10 km (Squyres et al. 1992). “Ridges are one of the main components of the deformation belts. Ridges are interpreted as contractional structures (large folds, thrusted antiforms). Individual ridges are convex-upwards, elongate features, of several km in width and tens of km in length. Commonly, ridges do not appear isolated, but organized in trains or bundles called ridge belts” (Fernández et al. 2010).
