Permian shales, sandstones, siltstones, limestones, sands, marls, and dolostones were deposited as a result of sea-level fluctuations. These fluctuation cycles can be seen in the rock layers. Relatively few sites lend themselves to direct radioactive dating, so the age of intermediate strata is often estimated.The increasing aridity of Pangaea doomed the beautiful reefs, but it ensured the future wealth of New Mexico and Texas.
