Tennessee Mineral Locality Index

Tennessee covers an area of 41,220 square miles in the southeastern United States. It a 500-mile-long state situated mainly between 35° and 36.6° North latitude and bounded on the west by the Mississippi River and on the east by high ridges of the Appalachian Mountains. It is geologically diverse. Traveling east from the Mississippi River the collector encounters relatively undeformed Cenozoic sediments of the Mississippi Embayment and Gulf Coastal Plain in the western part of the state. Just prior to crossing the Tennessee River and continuing through the middle of the state are weakly deformed Paleozoic sediments of the Highland Rim, Central Basin, and Cumberland Plateau. Continuing east beyond the Cumberland Mountains and Cumberland Plateau escarpment, the collector crosses moderately deformed Paleozoic sediments and rare igneous rocks of the Valley and Ridge, which change crossing the Great Smoky Thrust Fault to lower Paleozoic metasediments, Precambrian metasediments, and Precambrian to Paleozoic intrusive and extrusive igneous rocks.
