Fluid migration and associated diagenesis in the Greater Reelfoot rift region, Midcontinent, United States

摘要

The sources and pathways of basinal fluid flow on the North American craton have been the subjects of intense debate. Regional dolomitization and the distribution of petroleum and sulfide mineralization on the southern Midcontinent are believed to be related to migration of warm basinal fluids from and within the Arkoma and Illinois basins. Because of its hydrologic connection with these two basins, the Reelfoot rift has been postulated as a potential source and/or conduit for one or more of these fluids.
