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. Porter stated that the purple breccia is in the anticipated position of the Ordovician Plattin Limestone and that it probably extends into the underlying Joachim Dolomite. Ore minerals. > Pyroclastic Rock Ultramafic dikes, small stocks, and diatremes radiate from ). 4. The Santa Clara volcanic field in the southwest of the state is visible here. outward. 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. 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. Denny et al. It has been interpreted as resulting from explosions beneath the surface and therefore is referred to as a cryptoexplosive or cryptovolcanic feature.
