Lunar lavas are generated by melting at depths of 100 km or more. Rising to the surface is difficult unless there are deep fractures. That is why most lavas occur in impact basins, which make the deepest cuts into the lunar crust. Thus, the leaks of lava along the fault scarps of the Rook and Cordillera mountain rings, and in the center of Orientale are expected. And the crescentric patch on the floor of Schlüter at top right is probably lava that rose up a Cordillera fault but escaped just beyond the basin rim. At bottom right the big pond of mare lava is also on the floor of a basin, the Grimaldi Basin. And the dark lava on the floor of Riccioli, farthest to the right, is just inside the main ring of the Grimaldi Basin, in a position analogous to the lavas inside Orientale's rings. Finally, the dark skating ring floor of Crüger, and the puddles of Lacus Aestatis and " rel="nofollow Rocca A were inexplicable until LPOD revealed the answer.
