Outside the rim, a continuous ejecta blanket may be discerned.
After an impact event, the falling debris forms an ejecta blanket surrounding the crater.
The ejecta blanket becomes thinner with distance and increasingly discontinuous.
It was actually an ejecta blanket of dust and red sparks and steam.
The result is that both the crater and its ejecta blanket stand above the surroundings.
And it was the proper size - slightly less than a mile across, including the ejecta blanket.
Among this material there will be the ejecta blanket (section 3.3.5).
An alternative suggestion has been that the member represents part of the proximal ejecta blanket from an impact crater.
It is expected that the impact of such magnitude would have produced an ejecta blanket that should be found in areas around the lowland.
However, if the impact occurred around 4.5 Ga, erosional factors could explain the absence of the ejecta blanket.
