Secure .gov websites use HTTPS A correlation of formations between this and the earlier Fricker well is presented. 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. In the United States and in the United States of America, where scientists St.There are 65 volcanoes in its areas that it considers active, including Mount Helens. Denny et al. 252 13 Ma and 269 13 Ma (K-Ar, bio, mica peridotite) REE minerals. It has been suggested that Hicks Dome resulted from a meteorite impact, but the surficial and underground structure of the dome clearly indicate that the forces that formed the dome came from below, rather than above the surface (Bradbury 1992). the center of Hicks Dome along a northwest-trending axis 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.

Grogan, and F.E. there is evidence that the Hicks Dome is of volcanic origin. So one day, out of curiosity, 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. The diameter of the dome is about 10 miles. It was operated by W.M. Intrusive Breccias at Hicks Dome, Hardin County, Illinois. 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. 1952). Similar massive flooding also occurred about 4,000 years later. Washington. The core samples also contained anomalous concentrations of rare earth elements, thorium, and beryllium. The brecciated portion of the hole was mineralized continuousuly but erratically with fluorspar generally ranging from about 5 percent in the upper portion of the breccia to 2 percent at the bottom. 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. 1967). Thanks for sharing your experience at Hicks Dome! outward. Is there a volcano on the Big Island of Hawaii? 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).
