The phrase "ancient mare" is correct and usable in written English.
It can be used in contexts related to astronomy, specifically when referring to the large, dark plains on the Moon that are called "maria," which translates to "seas" in Latin, but are often referred to as "mares" in English.
Example: "The ancient mare on the Moon provides valuable insights into its geological history."
Alternatives: "old lunar plain" or "historic lunar sea".
Previous studies of dark haloed craters and light plains revealed the presence of cryptomaria (i.e., maria that were buried by ejecta from large craters or basins) and interpreted them as evidence for ancient mare volcanism (e.g., Schultz and Spudis, 1978, 1983; Hawke and Bell, 1981; Bell and Hawke, 1984; Antonenko et al., 1995).
Such ancient mare volcanism has been supported by radiometric analyses of rock samples returned from the lunar nearside (e.g., Taylor et al., 1983; Dasch et al., 1987; Nyquist et al., 2001) and lunar meteorites (Terada et al., 2007), which indicate ages of 4.2 4.35 Gyr for their basalt clasts.
In particular, Mussolini aimed at acquiring territory in Africa and in the Mediterranean, for which he adopted the ancient Roman term mare nostrum ("our sea").
Results indicate that the surface rock materials (including ancient crater materials, mare basalts, and possible SPA impact melt) are average to slightly elevated in K and Th with respect to the rest of the Moon.
The science objectives are to image the lunar South Pole, permanent shadow areas (ice deposit), eternal light (crater rims), ancient lunar non-mare volcanism, local spectrophotometry and physical state of the lunar surface, and to map high latitudes regions (south) mainly at far side (South Pole Aitken basin).
Southeast of Mare Imbrium, an ancient, lava-filled basin (foreground, above), a broad pattern of parallel grooves exists that doesn't point back toward the center of the basin itself.
Lead author Jose Madiedo, an astronomer at the University of Huelva in Spain, was working with two such telescopes last fall when a bright spot suddenly flared in the western part of Mare Nubium, a dark, ancient, lava-filled basin.
AP Avignon, the ancient city of alternative popes in Provence, hosts Terra-Mare, a major exhibition of the work of Mallorcan artist Miquel Barceló, in three venues this summer (27 June-7 November).
The original horses in Normandy and Brittany were small horses called bidets, introduced by the Celts, who settled in ancient Gaul beginning about the third century, B.C. Later, the Romans crossed them with larger mares.
Italy's fondest hope was to recreate the Adriatic as a mare nostra, heart of a resurgent Mediterranean Italian Empire that would mirror the lost glory of ancient Rome.
