==== In coronae ====
Craters are statistically up to ten times less numerous in the coronae than in the anti-Uranian regions, which indicates that these formations are younger.<ref name=Plescia1987_449>{{harvsp|J. B. Plescia|1987|p=449|id=Plescia1987}}</ref>

The density of impact craters could be established for different areas of Inverness, and made it possible to establish the age of each.<ref name=Plescia1987_450>{{harvsp|J. B. Plescia|1987|p=450|id=Plescia1987}}</ref> Considering these measurements, the entire geological formation was formed in a relative unit of time.<ref name=Plescia1987_451>{{harvsp|J. B. Plescia|1987|p=451|id=Plescia1987}}</ref> However, other observations make it possible to establish that the youngest zone, within this crown, is the one which separates the "chevron", from Argier Rupes.<ref name=Plescia1987_451/>

The density of impact craters in the core and in the Arden belt is statistically similar.<ref name=Plescia1987_450/> The two distinct parts of this formation must therefore have been part of a common geological episode.<ref name=Plescia1987_450/> Nevertheless, the superposition of craters on bands of the central core of Arden indicates that its formation preceded that of the scarps which surround it.<ref name=Plescia1987_450/> The data from the impact craters can be interpreted as follows: the interior and marginal zones of the corona, including most of the albedo bands, were formed during the same period of time.<ref name=Plescia1987_450/> Their formation was followed by later tectonic developments which produced the high-relief fault scarps observed along the edge of the crown near longitude 110°.<ref name=Plescia1987_450/>

The density of impact craters seems the same in the structure surrounding Elsinore as in its central core.<ref name=Plescia1987_452>{{harvsp|J. B. Plescia|1987|p=452|id=Plescia1987}}</ref> The two zones of the crown seem to have formed during the same geological period, but other geological elements suggest that the perimeter of Elsinore is younger than its core.<ref name=Plescia1987_452/>
