Shafts 24 to 154 feet deep were driven to a vein that averaged 4 feet wide, but no commercial production is on record (Weller et al. Ore mineralization has been found at this location, however the precise grade, tonnage, and extent of the mineralization are not known. However, slightly elevated values of copper and rare earth elements were suggested. The rocks are dated radiometrically as early Permian may be different as well. Historically the site has been associated with the Illinois-Kentucky Fluorspar Mining District which is now part of the Shawnee National Forest. IN THE BRECCIA ZONE, FLUORITE WAS 2 TO 5% AND ONE SAMPLE CONTAINED 12.8% CAF2. A peak's prominence, also known as topographic prominence or relative height, is a measure of how distinct a peak is from other peaks. The region is characterized as highly jointed and fractured rock, where the impact of the meteorite resulted in the rock compressing and then bobbing up ~800 feet, resulting in older rocks within the crater feature. Richard C. Berg, Director
The dome is about 10 miles in diameter, and rocks at its apex are uplifted 4,000 feet. Although their findings are highly speculative, Staatz et al. A normal sequence of formations was encountered down to 1,600 feet, but at about that depth the drill entered a confused brecciated zone, which persisted to the bottom of the hole at 2,944 feet. For more information purchase Geology of Illinois. Geologists working on the deposit designated the breccia as either complex breccia or host breccia. The dominant structural feature of the Illinois portion of the IKFD is Hicks Dome, an elliptical to nearly circular uplift approximately 10 miles in diameter in western Hardin County and northeastern Pope County. This is interpreted as one of the explosion type breccias, or diatremes, common in this Illinois-Kentucky area, as well as in nearby Missouri.

Don't show this message again The Pankey No. 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. Most geologists concur with Bradbury and Baxter (1992) that the dome is the product of large-scale igneous intrusion and brecciation at depth. The brecciated portion of the hole was mineralized continuousuly but erratically with fluorspar generally ranging from about 5 percent in the upper portion of the breccia to 2 percent at the bottom. Denny, F.B., A.H. Maria, J.L. Parallel with the fluorspar content and similarly diminishing downward is an abnormal radioactivity characterized by 0.029 percent eU in the upper part of the breccia zone. Its rocks are uplifted about 4,000 feet, with older rocks (Devonian) in the center, concentric rings of younger rocks (Pennsylvanian being the youngest), and many faults within. Middle Devonian rocks at the center are surrounded concentrically by younger rocks out to Pennsylvanian on the rim. This phenomenon was responsible for the fluorspar, zinc, lead, and silver that is found in the area. The region of Hicks Dome is rich in fluorite and other minerals.

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. xenotime. 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. It is associated with faults and fractured rock, and is accompanied by igneous rocks and mineral deposits. Save my name, email, and website in this browser for the next time I comment. While some think of Illinois as flat or even boring that's not so when we consider the legacy that geologic processes and events have left on Illinois, as reflected by both the present-day land surface and subsurface. 1920, J. Weller et al. 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. rectangular quadrants that are printed at 22.75"x29" or A lock () or https:// means youve safely connected to the .gov website. The borehole at the apex encountered Thanks to plate tectonics, the eastern U.S. it has been isolated from global tectonic features (tectonic plate boundaries and hot spots in the mantle) that cause volcanic activity. J.S. Also, ultramafic igneous dikes, breccias, and diatremes are present near the center of Hicks Dome (Bradbury and Baxter, 1992). of fluorite, apatite, and metal sulfides (Brown et al.

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. Located southwest of Hicks Dome, this prospect comprises several surface pits that follow veins striking N 4047 E (Weller et al. Illinois' megaquakes are the well-documented New Madrid events that occurred between Dec. 16, 1811, and March 15, 1812. approximately 4,000 feet (1,200 m). (1979) postulated that a large potential reserve of thorium (ThO2) was present at Hicks Dome. larger.
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. This location's average winter low temps are 1952, Brown et al. Similar massive flooding also occurred about 4,000 years later. Lava comes from a fissure in the Leilani Estates subdivision on Hawaiis Big Island on May 4, 2018.

If you witnessed a crime, you may be afraid that someone will retaliate against you for reporting it to the police. This is interpreted as one of the explosion type breccias, or diatremes, common in this Illinois-Kentucky area, as well as in nearby Missouri.

). 1952) and may have been owned by D.C. Peyton before 1917 (Pogue 1918). Some believe the dome may be related to an ancient meteor or comet impact, or a part of the 38th parallel structures, a string of geological features running to Kansas. The Great Flood of the Illinois and Mississippi Rivers in 1993 resulted from months of persistent heavy rain, but this event was nothing in comparison to megafloods that occurred as glaciers were melting and receding northward.

THORIUM PROBABLY ACCOUNTS FOR THE 0.029% EQUIVALENT URANIUM IN THE UPPER PART OF THE BRECCIA. 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. Some volcanoes are located near the subduction zones. Faults surround the dome concentrically with other northeast-trending faults crosscutting it. are younger than the dome and ultramafic intrusions. Champaign, IL 61820
