Mare Nectaris

Mare Nectaris (the "sea of nectar") is a lunar mare located within the Nectaris basin on the lunar nearside. The basin material is of the Nectarian[?] and Lower Imbrian[?] epochs, with the mare material of the Upper Imbrian[?] epoch. The crater Theophilus[?] on the northeastern side of the mare is of the Eratosthenian[?] epoch. Thus, the crater is younger than the mare to its southeast. Montes Pyrenaeus borders the mare to the west.

The mare material is approximately 1000m in depth. Enough subsistence has occurred to open a few arcuates grabens[?] on the western margin of the mare. The large crater near the south center of the mare is Rosse[?].
