TRACE, R.D., 1960, SIGNIFICANCE OF UNUSUAL MINERAL OCCURRENCE AT HICKS DOME, HARDIN COUNTY, ILLINOIS: USGS PROF. PAPER 400B P. B63 - B64. It is suggested that Hicks Dome is an incipient or uncompleted cryptovolcanic structure.Because of its location in the southern Illinois fluorspar-lead-zinc mining district, the cuttings were inspected carefully for these minerals. Examples of extinct volcanoes are Mount Thielsen in Oregon in the United States and Mount Slemish in Colorado.

It formed during the Permian, about 270 million years ago. It goes through the longest tunnel in Illinois. Most geologists who have studied Hicks Dome in southern Illinois, interpret it as the product of one or more underground explosions and is defined as a cryptoexplosive or cryptovolcanic feature (Nelson, 1995, Structural features in Illinois, Bulletin 100).

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. Most geologists accept the theory that the older rocks at the center of the uplift are a result of this deep-seated igneous activity. Most geologists who have studied Hicks Dome in southern Illinois, interpret it as the product of one or more underground explosions and is defined as a cryptoexplosive or cryptovolcanic feature (Nelson, 1995, Structural features in Illinois, Bulletin 100). These are the places where one of the Earths oceanic plates is pushed under another plate, another oceanic plate or a continental plate.

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. How many volcanoes are there in the United States? This is interpreted as one of the explosion type breccias, or diatremes, common in this Illinois-Kentucky area, as well as in nearby Missouri. trending mineralized block faults that cross Hicks Dome examples of inactive volcanoes are Mount Kilimanjaro, Mount Fuji in Tanzania, Africa and Japan.

Woolley, A.R., 1987, Alkaline rocks and carbonatites of the world; Part 1, North and South America: London, United Kingdom, British Museum of Natural History, 216 p. Thousands of people were called to leave their homes during the eruption of the Kilauea volcano, which was accompanied by recent earthquakes. 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.
