   • 1948, Josiah Edward Spurr, Geology Applied to Selenology: Lunar catastrophic history, page 48:

     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.

   • 1960, Valdemar Axel Firsoff, Strange world of the moon:

     On this reading of the situation, apart from the water of hydration, there will be very little chemical difference between lunarite and lunabase.

   • 1965, Gilbert Fielder, Lunar geology, page 85:

     Lunarite slopes at greater angles than lunabase, and the difference is due, it is suggested, to the lavas of the lunarite being relatively viscous.
