• Source: Smackover Formation

The Smackover Formation is a geologic formation that extends under parts of Arkansas, Louisiana, Texas, Alabama, Mississippi, and Florida. It preserves fossils dating back to the Jurassic period. The formation is a relic of an ancient sea that left an extensive, porous, and permeable limestone geologic unit.
The Smackover Formation consists of oolitic limestones and silty limestones.




Mineral resources



The Smackover Formation has been a prolific source of petroleum. The 1922 discovery of the Smackover oil field, after which the Smackover Formation is named, resulted in a sizeable oil boom in southern Arkansas.
In addition to being a petroleum reservoir, as of 2015, the brine from the Smackover Formation is the only source of commercial bromine in the United States.
A 2022 report estimated that the lithium brine in the formation has "sufficient lithium to produce enough batteries for 50 million electric vehicles." In October 2024, federal and state researchers announced the formation may hold five to 19 million tons of lithium, which is about nine times the annual worldwide demand for electric vehicles projected for 2030.
