Doppelmayer 2 is a typical effusive mare dome, with
a shallow flank slope, and low edifice volume. It was formed of lavas of a
viscosity of 105 Pa s that erupted at a high rate over a short
period of time of only half a year. It is characterized by the presence of
rilles on its summit. Doppelmayer 1 is atypically large, steep, and voluminous,
compared to lunar mare domes. It was formed of lava with a relatively high
viscosity of 107Pa s, which is between the ranges of values
typically observed for lunar mare domes and highland domes, respectively,
erupting at moderate rates over a long period of time of nine years.
Doppelmayer 1 is situated between classes C1
and B1, while Doppelmayer 2 belongs to the class C1.
