The Arion estate is located southwest of the Godall Range, on its northern slope. This mountain range is a horst (elevated block around it) made up of Mesozoic sedimentary material and that is part of the Catalan Coastal Range at its southern end. The Arion estate is at the foot of this terrain, where there is a change in the slope that has led to the accumulation of detrital material consisting of clays, sands and gravels from the Neogene age, and which has been accumulating at the foot of this terrain by the action of erosive forces.
