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. Three very large seismic events shook the region; more than 200 moderate to large aftershocks also occurred. of fluorite, apatite, and metal sulfides (Brown et al. 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.

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. Plutonic Rock Hicks Dome Hicks Dome was created by a volcano nearly 150,000,000 years ago. 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. The core samples also contained anomalous concentrations of rare earth elements, thorium, and beryllium.

Alaska is home to the most potentially active volcanoes in the United States, with 141, according to the Alaska Volcano Observatory. much breccia, but no conclusively igneous rock was 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). List of volcanoes in the United States A list of volcanoes in the United States and its territories. The volcano is called Hicks Dome. 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 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). Some volcanoes are located near the subduction zones. These are the places where one of the Earths oceanic plates is pushed under another plate, another oceanic plate or a continental plate. xenotime.

The small radial and arcuate faults that surround Hicks Hicks Dome is approximately 10 Hicks Dome, a cryptovolcanic feature in the northwestern part of the Fluorspar Area Fault Complex, played a key role in the structural evolution of the region. 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. It has been interpreted as resulting from explosions beneath the surface and therefore is referred to as a cryptoexplosive or cryptovolcanic feature.
