The Spatial Relationship of Graben and Pit Craters at Rimae Daniell and the Implications of Scarp FormationA geomorphologically complex and understudied region on the Moon is Rimæ Daniell,
situated in Lacus Somniorum. This region is characterized by a set of NNW-SSE-oriented grabens, which have been implied to be underlain by dikes through topographic measurements of ground displacements and faulting processes. The coverage of topographic measurements with the Lunar Orbiter Laser Altimeter (LOLA) aboard the Lunar Reconnaissance Orbiter (LRO) now allows for an indepth morphologic analysis of lunar grabens. Lunar grabens, in general, occur peripheral to some near-side mare units, within floor-fractured craters, and inside larger impact structures. From, LOLA data across Rimæ Daniell indicate that these grabens are located atop broad rises that stand 100–150 m above their surroundings. Although has mapped out the northwestern most grabens at Rimæ Daniell, this area has a complex geologic history, including pit chain craters and the transition of the graben system to a steep scarp, which is disrupted by knobby terrain.
