mare

mare

mare A large dark or low area on a planetary surface; pl.maria. The name, which means ‘sea’, is not a geological term; it was originally used in the 17th century, when the dark plains of the Moon were thought to be water, and was subsequently applied to the dark patches on Mars in the 19th century. The lunar maria are dark, smooth lowland plains of lava that erupted between the end of the late heavy bombardment 3.9 billion years ago and about 2 billion years ago. Samples of the maria have been obtained by the Apollo missions and unmanned Luna landers. The maria consist of solidified basaltic lavas, chemically and mineralogically different from the highlands, being enriched in iron and titanium, and with abundant pyroxene. The lunar mare lavas differ from those on Earth in that they were very fluid, with a viscosity similar to that of motor oil, so that they flowed for great distances. The Martian maria do not consistently correspond to any kind of topographical feature or geological province, and in most cases appear to consist of dark surface dust.

mare

mare (pl. maria) The Latin word for ‘sea’, originally used by Galileo in 1610 to denote the smooth, grey areas on the Moon, visible to the naked eye, that are now known to be plains of basaltic lava filling circular basins excavated by planetismal impact. Basalt lavas, mainly in maria, cover 17% of the surface of the Moon, mostly on the near side. The term is also applied to low-lying areas on Mars.
