The Marius Hills in Oceanus Procellarum represent the lunar region in which domes are most abundant. In the Marius Hills, low domes can be found as well as steep-sided features with rough surfaces, resulting from superposed flow lobes and cones and, often, steep domes are superimposed on low domes. Marius Hills domes presumably consist of several superimposed volcanic constructs, originated during several effusive phases. These domes are characterised by flank slopes ranging from 2° to 9° and diameters between 4.5 and 15 km. The small domes with D < 6 km belong to subclass H1. They are morphometrically similar to but spectrally bluer than similar domes of class E1 situated in the Milichius/T. Mayer region. Domes of subclass H2 with D > 6 km and flank slopes below 5.5° morphometrically resemble the steep domes of class B1 situated north of the crater Hortensius and in Mare Undarum, but their irregular shapes indicate a formation during several effusive episodes. Domes of subclass H3 have diameters comparable to those of monogenetic class B1 domes, but their flank slopes are all steeper than 5.5° and reach values of up to 9°.
