It is associated with faults and fractured rock and is accompanied by igneous rocks and mineral deposits. 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. 6873). however, for many people in such cases it is not cut and dried.

The geological forces that produced volcanoes in the eastern United States millions of years ago no longer exist. 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. (1955) reported small quantities of uranium in 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. part of the Fluorspar Area Fault Complex, played a key role Hicks Dome in Hardin County Illinois.

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. It has been interpreted as resulting from explosions beneath the surface and therefore is referred to as a cryptoexplosive or cryptovolcanic feature. It is associated with faults and fractured rock, and is accompanied by igneous rocks and mineral deposits. 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.

Hicks Dome, which is located in Hardin County, Illinois, has been an enigma for many years. 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. examples of inactive volcanoes are Mount Kilimanjaro, Mount Fuji in Tanzania, Africa and Japan.
