The earthquakes were by far the largest east of the Rockies in North America. 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). 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. Mines in the Illinois Portion of the Illinois-Kentucky Fluorspar District. The rocks are dated radiometrically as early Permian There is evidence that Hicks Dome is volcanic in origin. Farther outward, alternating resistant and 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. and at the apex of Hicks Dome (fig. xenotime. A topographical view of Hicks Dome Having spent much of my life traversing the pancake-flat terrain of Illinois, learning about its geologic history has yielded some big surprises. 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. outward. Hiking in the Shawnee National Forest - Features the most popular hikes and trails to explore in Southern Illinois. 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. The trip will conclude with a walking tour at the Garden of the Gods Recreational Area to view the Eagle Valley Syncline and Lower Pennsylvanian units. The diameter of the dome is about 10 miles. Most geologists accept the theory that the older rocks at the center of the uplift are a result of this deep-seated igneous activity.
