Meanings
- uncountableThe substance that forms the darker areas of the lunar surface, as opposed to lunarite.
On this reading of the situation, apart from the water of hydration, there will be very little chemical difference between lunarite and lunabase.
1960, Valdemar Axel Firsoff, Strange world of the moon3 more examples
The melting conditions in the lunarite were evidently different from those in the lunabase, on account of the difference in chemical composition; and from analogy with terrestrial conditions, the latter melted more easily.
1948, Josiah Edward Spurr, Geology Applied to Selenology: Lunar catastrophic history, page 48Lunarite slopes at greater angles than lunabase, and the difference is due, it is suggested, to the lavas of the lunarite being relatively viscous.
1965, Gilbert Fielder, Lunar geology, page 85Some crater rings show faintly through the lunabase; others just break surface. Some lunabase areas such as the floor of Petavius are faulted, which may reasonably be attributed to very thin, plastic lunabase cover over a brittle substratum.
2014, Frederick I. Ordway, Advances in Space Science and Technology, page 42
