LUNAR GRABEN SYSTEMS
BK Lucchitta & JA Watkins, Ages of Graben Systems on the Moon. Proc. Lunar & Planet. Sci. 9, 3459-3472 (1978).
This paper recognized that lunar rilles,or graben, typically are not isolated features, but are clustered into groups or systems. Rilles within a system presumably have a related origin. The rilles in these systems are mostly linear and arcuate rilles, not sinuous ones. CAW

Note: I don't agree with all of these names because they imply connections with specific basins, which may not always be true. DL is a measure of the age of a lunar surface, based on models of crater erosion. The lower the number the younger the surface; thus all DL values for maria that flood rilles (i.e., are younger) are smaller than the Dl values for the maria cut by the rilles.
