The lunar highlands are older than the maria because they have accumulated more impact craters over time. This suggests that the highlands are composed of older, more geologically stable rock compared to the volcanic plains of the maria.
They are impact basins that have been flooded with (once-molten) lunar basaltic lavas, which are naturally dark in color.
