Abstract: In 1952, St. Joseph Lead Company drilled a well on the apex of Hicks Dome in Hardin County, Illinois, primarily to explore for oil or gas, and with the objective of testing the St. Peter sand horizon, which had not been reached in a previous well on the flank of the dome. Brown, J.A. Bradbury et al. Like most previous researchers, Bradbury Woolley, A.R., 1987, Alkaline rocks and carbonatites of the world; Part 1, North and South America: London, United Kingdom, British Museum of Natural History, 216 p. Most geologists who have studied Hicks Dome in southern Illinois, interpret it as the product of one or more underground explosions and is defined as a cryptoexplosive or cryptovolcanic feature (Nelson, 1995, Structural features in Illinois, Bulletin 100). Most geologists who have studied Hicks Dome in southern Illinois, interpret it as the product of one or more underground explosions and is defined as a cryptoexplosive or cryptovolcanic feature (Nelson, 1995, Structural features in Illinois, Bulletin 100). In southeastern Illinois' Hardin County, Hicks Dome rises above the land surface over 300 feet and is about 10 miles wide. Porter stated that the purple breccia is in the anticipated position of the Ordovician Plattin Limestone and that it probably extends into the underlying Joachim Dolomite. V. 49 NO. The Hicks Dome uplifted ~1200 meters, observed from the west. The region of Hicks Dome is rich in fluorite and other minerals. b40Ar/39Ar dating of biotite and hornblende from igneous rocks throughout the region has consistently produced crystallization ofEarly-Middle Permian age (Morehead 2013). Alaska. A correlation of formations between this and the earlier Fricker well is presented. much breccia, but no conclusively igneous rock was The Hicks Dome is underlain by ultramafic igneous rocks and igneous diatremes or breccia pipes. Historically the site has been associated with the Illinois-Kentucky Fluorspar Mining District which is now part of the Shawnee National Forest. Igneous diatremes are scattered throughout the region, and nearly vertical dike-like intrusive breccia bodies radiate from the center of Hicks Dome (Baxter et al. The dome is about 10 miles in diameter. beneath the dome, as would be expected if a large mafic body Although their findings are highly speculative, Staatz et al.

Terms of use In 1969 and 1970, the Industrial Minerals Company excavated additional pits and recovered approximately 436 tons of ore grading 53% CaF. Several test holes drilled near the crest of Hicks Dome disclosed significant mineralization in the Ordovician strata over a thickness of more than 200 feet. Klauea Volcano on Hawaiis Big Island is the most dangerous volcano in the United States, according to the latest National Volcanic Threat Assessment from the United States Geological Survey (USGS).
