Geology of Oklahoma
Oklahoma's diverse geology dates back to the Precambrian Era, over 1 billion years ago, when ancient granite and other igneous rocks formed the core of the state. Later, during the Paleozoic Era, Oklahoma was submerged under a shallow sea, leading to the deposition of limestone, sandstone, and shale layers.
Throughout the Mesozoic Era, Oklahoma was part of the Western Interior Seaway, which resulted in the formation of additional sedimentary layers. During this time, dinosaurs roamed the land, leaving behind numerous fossils. The Cretaceous Period saw the emergence of the Ouachita and Arbuckle Mountains as a result of tectonic forces.
During the Cenozoic Era, the state experienced periods of uplift, erosion, and sedimentation, which shaped its present-day landscape. The Panhandle region of Oklahoma is known for its Ogallala Formation, an important aquifer that was formed from sediments deposited by ancient rivers.
Today, Oklahoma's geology provides a wealth of rockhounding opportunities, with its diverse mineral resources, including gypsum, limestone, sandstone, granite, and various ores. The state's geological history is also evident in its unique landforms, such as the Wichita Mountains and the Glass Mountains.
