They call it the foil to Astrologian, painting the contrast of heavenly and earthly energies, but as far as I'm aware there is actually nothing in the game where Geo heals. In the lore they're known for being powerful casters doing things like bringing down airships. I'm not saying its impossible it just does seem to fit when you look at the job as a whole within and without the game's lore.
In the level 70 quest, the geomancer has three spells.

Qi of Air - this is the same as aero from white mage
Qi of Earth - this is the same as stone
Qi of Water - this one is actually a cure spell.

So in the game, there is a precedent of geomancers having healing magic.
