Detailed Mechanics
For geology ranks 1-3, the actual effect is that you have a 50% chance to loot an additional unit of the specific inorganic resource you are manually mining/harvesting. For gas/liquid nodes, you have two separate 50% chances to loot an additional resource. As an additional note, every character (regardless of geology skill) gets a 50% chance to get a bonus resource from gas/water nodes, therefore with geology you can loot anywhere from 1 to 4 quantity.

For geology rank 4, you have two separately rolled 25% chances to loot a rare (rarity = 2) resource when gathering, and one 25% chance to loot an exotic (rarity = 3) resource when gathering. The resource chosen will be of the same category (gas/solid/liquid) as whatever you're mining, but is otherwise completely random, and does not need to exist on the planet naturally.
