资源简介：
This map is one of a series prepared from photographs transmitted by Ranger IX (Jet Propulsion Lab, 1966, pls A56-58, B70-82). It depicts the geology of some 724 sq km in the northeast part of the floor of Alphonsus (Diameter about 115 km), a typical flat-floored old terra crater or basin with a subdued rim. Similar basins abound in the south central terrae of the visable hemisphere and on the far side of the Moon. Alphonsus is of particular interest, however, because of a well developed interior rille system and associated dark-halo craters.
