This mineralization ranges from world-class ore districts to numerous smaller ore fields. Previous research has established that, in addition to ore grade mineral accumulations, subsurface midcontinent Paleozoic rocks distal to ore-grade mineralization acted as regional conduits for ancient ore-forming fluids. These ore fluid-bearing aquifers now contain trace levels of mineralization including lead and other potentially toxic elements such as arsenic and cadmium. Centuries of mining and the interaction between modern groundwater and trace-metal-bearing aquifers resulted in creation of exposure pathways for these toxic elements to impact modern sedimentary, hydrologic, and biotic environments. The list of known and potential environmental impacts is long." }, { "@type": "TextObject", "text": "The overall project objective is a comprehensive analysis of the natural and anthropogenic consequences of extensive ore and trace mineralization in the southern midcontinent of the U.S. with a focus on Missouri.
