Description
The Procellarum Basin is a putative very ancient and very huge impact basin on the Moon's nearside. Its existence was proposed by Cadogan in 1974, with further contributions by Whitaker in 1981. Although its existence is still regarded as uncertain by many, it is a major player in Wilhelms' Geologic History of the Moon, where it is regarded as the oldest still recognizable large impact basin on the Moon. - JimMosher JimMosher
Additional Information
- P. H. Schultz has been particularly vocal in expressing doubts about the existence of the Procellarum Basin. In his 1995 article he suggests that the tell-tale rings that were used as evidence of its existence are instead much later formations and the expected consequences of an oblique impact forming the Imbrium Basin. - JimMosher JimMosher
Nomenclature
- Cadogan proposed the name "Gargantuan Basin". However Whitaker noted that basins enclosing maria are normally named for the mare they contain. Hence, since the mare of Oceanus Procellarum had not been assigned an impact basin, he proposed the less colorful name "Procellarum Basin", which seems to be more widely used of the two names. Like all basin names, these are informal, and not part of the IAU nomenclature.
- Is this the same as Charles J. Byrne's Near Side Megabasin? (see his book The Far Side of the Moon, A Photographic Guide) (Springer, 2008).
