Mare Imbrium lava flows and their relationship to color boundaries, part MThe Apollo 15 metric camera photography provided a number of spectacular views of most of the southern and central portions of the unique systems of major lava flows that stretch diagonally across Mare Imbrium from the general area of Euler Crater to a point east of Le Verrier Crater. A preliminary examination of the photographs indicates that the source of the material comprising the major flows is situated to the west of Euler Crater and south of the limits of the photographic coverage. The photographs also show clearly that most, if not all, the mare ridges included were formed after the solidification of the flows. Few color boundaries exist in the area of metric photography where the illumination angle is low enough to show the fronts of some of the very thin flows. However, patches of redder material lying northeast of Mt. Lahire are found to be enclosed by low flow fronts, confirming the theory that the redder material represents an earlier filling of the Imbrium basin.
