Description
Cooper lies some 100 km away east of D'Alembert crater -- a 248 kilometre-wide crater of the Nectarian (~ 3.92 to 3.85 bn years) period. From its appearance Cooper is older than Nectarian, as nearly all of its rim and floor regions show signs of degradation, bombardment, and a recipient of ejecta deposits from, for example, Mare Moscoviense nearby to its south-west. Nearly all of the crater's original rim has been obliterated by numerous small impacts -- particularly at its eastern sectors, while its floor show characterisitcs of reshapement, re-mixing of in-situ materials with above-mentioned ejecta deposits; burying, perhaps, a history of the crater itself. - JohnMoore2 JohnMoore2
