Summary:Diagenesis of the St Peter sandstone is controlled by detrital mineralogy which in turn is controlled by the sandstone's depositional environment. Beachface sandstones (quartz-rich with no detrital or early diagenetic matrix) show abundant quartz cement followed by burial dolomite or anhydrite, either followed by dolomite dissolution or additional quartz cement. Sandstone from less energetic depositional environments (containing detrital feldspar and micritic calcite matrix) show early dolomitization of the micrite followed by dolomite dissolution and authigenic illite formation in secondary pores. Position in the basin or burial depth do not appear to control diagenesis. Diagenetic dolomite is calcic with an average molar composition of 61% Ca, 35% Mg, 4% Fe. [J.L.W.]
