Paleontology and geology
Igneous, metamorphic and partially metamorphosed sedimentary rocks from the Cambrian can be found in the Carolina Slate Belt in central North Carolina. These rocks may have been part of an exotic terrane that collided with North America during the Ordovician. In general, few sedimentary rocks were deposited in North Carolina during the Cambrian. One exception can be found in westernmost North Carolina: a Cambrian-age basin in which clastic sediments (sands and muds) and carbonates were deposited. While trilobites have been found in Cambrian rocks from South Carolina, no fossils have been found in these rocks in North Carolina.
