Lunar volcanism, mostly mare lavas and some pyroclastics, occurs largely within and near impact basins. There are leaks of volcanic material. Here is another one, centered at 166°E and 1.8°S. This cluster of dark material is scattered around small craters just north and east of 50 km wide Dewar. These look like normal impact craters, so presumably the dark material is buried basaltic lavas (or igneous intrusions - magma that hasn't erupted) that have been excavated by the impacts. The question is why are these volcanic rocks near enough the surface to be brought up by small crater impacts, but have not erupted on their own?
