Hicks Dome (37°31′53″N 88°22′06″W / 37.53139°N 88.36833°W / 37.53139; -88.36833) is an interesting geological feature in Hardin County. Some believe the dome may be related to an ancient meteor or comet impact, a part of the 38th parallel structures, a string of geological features running to Kansas. Some believe this to be a string of impact craters from a body that broke apart prior to hitting the earth.[citation needed] The Hicks Dome is underlain by ultramafic igneous rocks and igneous diatremes or breccia pipes. Most geologists currently accept the theory that the older rocks at the center of the uplift are related to this deep seated igneous activity. This igneous activity may have also provided the fluorine for the fluorspar deposits in this region. Josie akin Fluorspar, or calcium fluoride, was mined in Hardin County until the early 1990s.
