Mississippi Rock and Minerals
Mississippi does not have many rock and mineral resources.
Much of Mississippi is built of sand, gravel, and mud brought down by the Mississippi River and which has filled a great bay in the Gulf Coast. The surface rises from the Gulf Coast and the river toward sedimentary rocks in the state that form a ridge in the northeast counties. Thus, petrified wood, jaspers and agates in the river gravels is the primary source of collectible rocks.
Mississippi has produced both oil and gas. Most of Mississippi's oil fields are located in the southern half of the state. All of the state's coal production comes from one mine that supplies lignite, which has a lower heating value and higher moisture content than other types of coal.
The W.M. Browning Cretaceous Fossil Park is a small site in northeast Mississippi where anyone can dig for 75-million-year-old fossils. The park is located north of the city of Baldwyn, on Twenty Mile Creek at the intersection of U.S. Route 45 and road 7450. Excavations at this site have uncovered abundant shark teeth and other fossils from the Cretaceous age. Some fossils are found in the boulder-sized concretions in Twenty-mile Creek, but the greatest concentration was found below an oyster bed 40-feet higher.
Before venturing out-do some research on where and what you can collect. Remember you must have permission to collect on private property.
