An aulacogen is an arm of the rift that fails. That is, rifting stops on this arm, but continues on the main rift as an ocean basin opens. The Uinta aulacogen constituted an arm of the new ocean basin that was filled with the sandy sediment that later became the Uinta Mountains.

Interpreted geologic bodies associated with the pre-Grenville rift (PGR), Delaware aulacogen (DA), Abilene gravity minimum (AGM), and Crosbyton anomaly (C) are shown, along with two proposed new locations for the Grenville front in Texas.
