Lunar Mare Ridges: Analysis of Ridge-Crater Intersections and Implications for the Tectonic Origin of Mare Ridges

Abstract

We have investigated the nature of ridge-crater intersections to gain a better understanding of mare ridge formation. Distinct evidence of ridge-related deformation was observed in 65 small craters within the lunar maria Our results indicate that ridge deformation within these craters is inconsistent with any type of lateral transport such as volcanism or mass wasting. Instead, these ridge segments appear to consist of crater floor materials uplifted along nearly vertical splay faults.
