Searching for deep-seated thrust faults on the moon

Matthew Collins
The lunar maria are large expanses of basalt that infill antecedent impact basins and show evidence for post-emplacement deformation. Landforms within many of these basins suggest a period of compressive tectonics, although the mechanism for their formation remains an open question. Previous work for Mare Crisium demonstrated that basin-circumferential wrinkle ridges, which typically demarcate the inner edge of an annulus of elevated terrain, are the result of deep-seated thrust faults that preferentially form along the...
