dc.description.abstract	This paper presents observational evidence, based on Viking Orbiter and Lunar Orbiter photographs, for the morphological similarity between grooved features found in the Memnonia and Phaethontis quandrangles of Mars and the lunar Imbrium Sculpture materials. The grooved structures radiate from a source area at the approximate center of Daedalia Planum. These features are indicative of an ancient impact basin. Geologic materials, volcanolike massifs, and earth-based radar data confirm the existence of a 4500-km-diam impact basin centered in Daedalia Planum. Ages determined by geologic mappers for associated basin materials suggest that the basin was formed in the early Noachian, making the Daedalia basin one of the oldest identified basins on Mars.	en
