The Permian Chert Event (PCE) was an unusual global chert accumulation that reflects tectonic–climatic–environmental changes during the late Paleozoic. South China was located near the equator in the eastern Paleo-Tethys Ocean at this time, and this region developed massive chert deposits during the Permian as part of the PCE.
Brachiopod Fossils. The most common seashells at the beach today are bivalves: clams, oysters, scallops, and mussels.

This resulted in an inland sea where evaporation greatly exceeded fluid intake, and a great thickness of "evaporite" sediments was deposited; one of these was potash, a critical commodity during World War I, until then a product obtained from Germany. Overlying the Glorieta Sandstone in the park are limestones, minor dolomites, shales, siltstones, and gypsum of the Permian San Andres Formation. The upper San Andres limestone beds locally contain fossils (Smith, 1954). The San Andres Formation was deposited along the bottom of the shallow epicontinental Permian sea.
