WebNonetheless, carbonate sediments proceed in a general way through the same diagenetic regimes as siliciclastic sediments. That is, carbonate sediments go through early (shallow-burial), middle (deep-burial), and possibly late (uplift and unroofing) stages of … WebDec 9, 2024 · Third, early marine diagenesis in shallow-water carbonate sediments can occur under both fluid- and sediment-buffered conditions, depending on the extent to which pore-fluid exchange with seawater occurs through advection or diffusion (Banner and Hanson, 1990; Fantle and DePaolo, 2007; Fantle and Higgins, 2014; Higgins et al., 2024).
WebCarbonate minerals in modern marine sediments can readily be divided into those found in shoal-to-shallow and deep-water environments. The factors controlling the sources, mineralogy, and diagenesis of carbonates in these environments are very different.
