In southeastern Illinois' Hardin County, Hicks Dome rises above the land surface over 300 feet and is about 10 miles wide. 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. The possibility is suggested that this could have been picked up from the formerly overlying New Albany, or Chattanooga, shale (Brown 1954). The nearest weather station for both precipitation and temperature measurements is ROSICLARE 5 NW which is approximately 5 miles away and has an elevation of 400 feet (266 feet lower than Hicks Dome). 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. outward.

Age of deposit. Thanks for sharing your experience at Hicks Dome! Drilling into the core of Hicks Dome reveals greatly shattered sedimentary rocks, intermixed with igneous material. In the application for financial assistance in minerals exploration that the Hicks Dome Corporation submitted to the Office of Mineral Exploration, Porter stated that the ore deposit beneath Hicks Dome contained several mineralized purple breccia matrix blocks that were located about 500 to 750 feet beneath the Maquoketa Shale. Brock 1961, McGinnis and Bradbury 1964, Baxter and Desborough 1965, Baxter et al. The roughly circular dome has prominent topographic expression on aerial photos and satellite images. The Hicks Dome, a Permian crypto-volcanic feature (?) This location's average summer high temps are 2 hole was drilled to 2,485 feet, and the core was composed of breccia cemented by white calcite, with sparse fluorite in the upper portion, but fluorite averaged between 2% and 8% from 2,000 to 2,240 feet. there is evidence that the Hicks Dome is of volcanic origin. This is much deeper than previously known in such amounts in the area. 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. beneath the dome, as would be expected if a large mafic body Mulvaney-Norris, R.N.

The origin of Hicks Dome is clearly related to igneous Bradbury and Baxter (1992) described three types of breccias topographic maps of the U.S. called US Topo that are separated into Don't show this message again Bradbury et al. Geologically, the region of volcanic rocks is called the Midwest Permian Ultramafic district The district lies within the southern part of the Illinois Basin at the juncture between the Reelfoot Rift and Rough Creek Graben. fracturing at the juncture of the Reelfoot Rift and Rough Creek Graben provided pathways for mantle-derived magmas to intrude into the sedimentary column. 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. It is about five miles in diameter, less than 280 million years old, is buried beneath the land surface, and exhibits shatter cones, which form below impact craters as a result of rock being subject to extreme shock and pressure.

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. Middle Devonian rocks at the center are surrounded concentrically by younger rocks out to Pennsylvanian on the rim. The mine was active in 1928 through the spring of 1929 and produced a small amount of ore, which was shipped to Marion, Kentucky, to be milled (Davis 1929). Faults surround the dome concentrically with other northeast-trending faults crosscutting it. 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.
