Historically the site has been associated with the Illinois-Kentucky Fluorspar Mining District which is now part of the Shawnee National Forest. higher than 55% of other locations on record. 3 was composed of brecciated limestone or crackled limestone cemented by 4-millimeter-thick bands of purple fluorite and calcite, with the percentage of fluorite increasing at 2,000 feet. Middle 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. This page was last edited on 22 July 2021, at 16:20. The dome has small associated igneous dikes around its flanks. Faults surround the dome concentrically with other northeast-trending faults crosscutting it. Hicks Dome is approximately 10 The Hicks Dome, a Permian crypto-volcanic feature (?)

Although their findings are highly speculative, Staatz et al. there is evidence that the Hicks Dome is of volcanic origin. This is much deeper than previously known in such amounts in the area. Davis, H.W. Is Hicks Dome a volcano? It is suggested that Hicks Dome is an incipient or uncompleted cryptovolcanic structure.Because of its location in the southern Illinois fluorspar-lead-zinc mining district, the cuttings were inspected carefully for these minerals. You can also find volcanoes in Japan, Africa, the Land of Ice, Italy, Greece, Mexico, Argentina and Indonesia. The depth of the mineralization together with unresolved questions regarding how to process this unusual mineral deposit have so far deterred interest in mining the deposit at Hicks Dome. > Pyroclastic Rock Due to near-surface magmatism, the apex of the dome has been uplifted three-thousand feet, and multiple hydrothermally altered ultramafic dikes have been exposed. Drilling into the core of Hicks Dome reveals greatly shattered sedimentary rocks, intermixed with igneous material. higher than 79% of other locations on record. District.

IN THE BRECCIA ZONE, FLUORITE WAS 2 TO 5% AND ONE SAMPLE CONTAINED 12.8% CAF2. Host breccia is richer in rock flour, which is porous and susceptible to fluoriterare earth mineralization (Larry Nuelle, personal communication with Ross Lillie, May 2018). a maximum of about 20 (as much as 45 locally) about 1 mile Hardin County Summits (16) Extinct Illinois Volcano, Hicks Dome in Hardin County is a feature that is both a topographic and structural dome forming a bull's-eye pattern on a geologic map.

The Kankakee Torrent exhibited massive amounts of water flowing down the rivers about 19,000 years ago; this resulted from glacial melting, lakes forming behind moraines, and then moraines becoming breached. The Hicks Dome, a Permian crypto-volcanic feature (?) Because the nearest station and this geographic feature may have differences in elevation and topography, the historic weather at the two separate locations may be different as well. Utah Utah has four volcanic fields. Ore minerals. Hamp No. It has been suggested that Hicks Dome resulted from a meteorite impact, but the surficial and underground structure of the dome clearly indicate that the forces that formed the dome came from below, rather than above the surface.

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). It is associated with faults and fractured rock and is accompanied by igneous rocks and mineral deposits. 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. Emery, P.A.
