Geomantic Reservoirs are locations scattered across Vana'diel. A Geomancer who interacts with one of these spots after learning the appropriate indicolure spell will learn the geocolure version of that spell. Indicolure spells can be purchased from Ishvad and Eukalline on the Western Adoulin waterfront.
It is possible to also obtain a skill up from these reservoirs when a spell is learned. When you see a blank line after confirming "The arcane energies begin to course within your veins" appears, wait until a 
appears above your character's head. Once you see the appear, immediately press enter. You will receive a skill up depending on your timing, up to a maximum of a 0.9 Geomancy skill gain.
