from The Century Dictionary.

  • Pertaining to or containing labradorite.


Sorry, no etymologies found.


  • Although vocanoes are justy termed in many languages "fire-emitting mountains," mountains of this kind are not formed by the gradual accumulation of ejected currents of lava, but their origin seems rather to be a general consequence of the sudden elevation of soft masses of trachyte or labradoritic augite.
