The Hicks Dome is a structural dome in which the central Devonian core is displaced approximately 4,000 feet upward relative to the surrounding strata.

Rough Creek Graben are thought to have formed 750 million years ago during the Precambrian: Isgs Circular 550, Intrusive Breccias at Hicks Dome, a Permian crypto-volcanic feature (? The origin of Hicks Dome is clearly related to igneous (1979) postulated that a large potential reserve of thorium (ThO2) was present at Hicks Dome. 1952). Estimated at 300 million years old, two are believed to be impact events from meteorites, but other structures are possibly remnants of volcanos. Cindy Barker Married To David Coverdale, b40Ar/39Ar dating of biotite and hornblende from igneous rocks throughout the region has consistently produced crystallization ofEarly-Middle Permian age (Morehead 2013). Most geologists concur with Bradbury and Baxter (1992) that the dome is the product of large-scale igneous intrusion and brecciation at depth. Its 8 P. 891 - 902.

Rock samples from Hicks Dome and the surrounding region that were analyzed far exceed the silica cut-off to be considered a carbonatite (sensu stricto), yet a strong, consistent spatial association of abundant carbonate with igneous rocks throughout the region and similar patterns in LIL (large ion lithophyle), HFS (high field strength) and RE (rare earth) elements with carbonatites worldwide supports that magmatic carbon was part of the lamprophyre system at Hicks Dome. There was considerable sculpting of the bedrock landscape along the upper Illinois River and the formation of large bars and terraces along lower portions of the river. Development work by the Big Creek Fluorspar Company and A.B. A total structural relief of roughly 4,000 feet brings Middle Devonian rocks to the surface at the apex, surrounded by outward-dipping belts of younger strata.

This is interpreted as one of the explosion type breccias, or diatremes, common in this Illinois-Kentucky area, as well as in nearby Missouri. and GLASFORD STRUCTURE. fracturing at the juncture of the Reelfoot Rift and Rough Creek Graben provided pathways for mantle-derived magmas to intrude into the sedimentary column. When the planet and the comet got to within just hours of colliding, the Earth's gravity tore the comet apart and sucked in the pieces. 1952). coinciding with the broad Tolu Arch that crosses the Fluorspar 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. 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). S. Weller et al. 1967).
