Guess #2: Fire + Lightning = Lava. Lava + Water = Earth.

Of course, this system feels very similar to Grandia.

Water + Wind = Ice, Fire + Wind = Blaze, Wind + Lightning = Storm

Then again, maybe different effects are garnered simply by utilizing Dust in higher concentrations. Maybe Lava is simply fire Dust at 50% while Burn is 5-10%...
