What rocks were preserved from Arkansas springs?

The rocks preserved from Arkansas springs primarily include sedimentary formations, such as limestone, which often contains fossils and mineral deposits formed from the precipitation of calcium carbonate. Additionally, some regions feature sandstone and shale, reflecting the geological history of the area. The mineral-rich waters of these springs also contribute to the formation of unique mineral deposits, including barite and calcite, which can be found in the surrounding rock formations. These geological features provide insight into the ancient environments and processes that shaped the region.
