TheEminescuquadrangle (H-9) is one offifteen quadrangles on Mercury. It runs from 216 to 288° longitude and from -25 to 25° latitude. Named after theEminescu crater, it was mapped in detail for the first time afterMESSENGER entered orbit aroundMercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated whenMariner 10 made its flybys in 1974 and 1975. These six quadrangles continued to be known by theiralbedo feature names, with this one known as the Solitudo Criophori quadrangle.^[1][2]

An unnamed, highly modified impact basin is thought to exist to the southwest of the Caloris basin (at 6.5° N, 134.8° E). The basin is referred to asb40 in scientific literature and it is primarily recognized on the basis of a ring-shaped set of wrinkle ridges with a diameter of 310 kilometers.^[3] The western rim of this basin is named Arquipelago Rupes.^[4]

Derain quadrangle is to the west of Eminescu quadrangle, andTolstoj quadrangle is to the east.Hokusai quadrangle andRaditladi quadrangle are to the northwest and northeast, andDebussy quadrangle andNeruda quadrangle are to the southwest and southeast.
