Lunar mare ridges - Analysis of ridge-crater intersections and implications for the tectonic origin of mare ridgesModels proposed for the origin of lunar mare ridges belong to one of the three categories: volcanic, tectonic, and a combination of volcanic and tectonic. This paper presents the results of an analysis of ridge-crater intersections in Oceanus Procellarum and Maria Cognitum, Imbrium, and Serenitatis and examines the range of fault attitudes and displacements associated with mare ridge development. The results indicate tectonic, rather than volcanic, involvement. The evidence cited to support a volcanic origin for mare ridges is reassessed. In addition, plausible end-member tectonic models are presented.
