A survey of the literature indicates that, compared to                     shales and sandstones, relatively little micropetrographic work                 (SEM-EDX,  electron probe) has been done on authigenic and                      diagenetic clay minerals in carbonate rocks.  This project is a                 micropetrographic investigation of the Upper Mississippian                      shelf-tidal flat carbonates, which occur in excellent exposures                 along the edge of the Cumberland Plateau (TN).  These rocks                     contain a wide variety of possible authigenic/diagenetic clay                   minerals (Ch/S, Ch/V, corrensite, vermiculite, illite, I/S).  A                 preliminary SEM-EDX study (Fig. 1-3) confirms the presence of                   authigenic/diagenetic I/S (4:1) in the interior of calcite                      oolites.                                                                             The study will concentrate on the Upper Mississippian                      carbonates and establish the genetic relation of the Mg clays and               K clays to calcite, dolomite and the various shallow carbonate                  environments.  In addition to chemical, mineralogical, and petro-               graphic data will be obtained on spatial and volume data so that                mass balance calculations can be made for Mg and other ions.  In                addition  to obtaining information of the origin of the clay                    minerals, we will obtain information on the factors effecting the               partitioning of Mg between silicate and carbonate minerals.  The                goal of this research is to determine the nature, significance of               clay mineral reactions in carbonate rocks, shedding light on                    diagenetic processes.
