Maria are medium- to large-size mostly circular flat-floored low-albedo plains on the Earth’s Moon and the Saturnian satellite Titan. On the Moon maria are formed by basaltic flood volcanism and are predominant on the lunar nearside. On Titan, maria are postulated to be filled with liquid hydrocarbon compounds, in particular methane and ethane.
Overview
The term mare originally referred to large-size low-albedo features on the Moon. Lunar mare are lava plains characterized by low-viscosity basaltic flood lava. The use of the term mare has been extended to other terrestrial bodies in the solar system, especially to Titan where maria are radar-dark features that are assumed to be large lakes of liquid hydrocarbon compounds.
On the Moon, the term mare basinrefers to an impact structure filled by flood lava. Although lunar maria and impact basins are spatially related, mare materials were emplaced later when compared to impact basins...
