Abstract
The origin of the Upper Mississippi Valley mineral district from Illinois basin brines is tested by two mathematical models of water flow northward out of the basin. Compaction-driven ground-water flow during basin subsidence is inadequate because of its failure to redistribute heat. Gravity-driven flow due to uplift of the Pascola arch at the S end of the Illinois basin is capable of having introduced warmed fluids to the Upper Mississippi Valley district.-G.J.N.
