The volcanic domes, cones, sinuous rilles, and pyroclastic deposits of the Marius Hills region Moon (~13.4°N, 304.6°E) represent a significant episode magmatic activity at or near lunar surface that is still poorly understood. Comparisons between LROC NAC block populations, Mini‐RF data, Diviner‐derived rock abundances confirm blocky lava flows comprise domes Hills. 8 µm features measured by Diviner indicate are not rich in silica significantly different than surrounding mare materials. observations some dome‐building originated directly from cones. Many cones C‐shaped, while others irregularly shaped, local topography eruptions affect cone shape. In general, morphologically similar to terrestrial cinder composed varying amounts cinder, spatter, lava. found groupings alignments. wide range features, broad low steep represents variable eruption conditions. Complex morphologies layering show conditions were over plateau.
