Occasional interbeds of fine-grained carbonate may reflect gravity input of peri-platform ooze, rather than sea-floor preservation of calcium carbonate.
True thickness of the carbonate deposits is unknown due to folding, but it certainly was in the order of hundreds of metres or more.
Furthermore, volcanism coincided with prominent changes in local basin development, following collapse of the carbonate platform in this foreland basin.
Higher up in the sedimentary record, calcite becomes the most prominent carbonate mineral.
Low-temperature, fine-grained, alteration products include serpentine, talc, bowlingite, white mica, epidote s. l., carbonate and opaques.
Ichnofossils and ichnofabrics in rhythmically bedded pelagic/hemi-pelagic carbonates: recognition and evaluation of benthic redox and scour cycles.
The second geological outcrop was partly covered by a crust of sulphate and carbonate minerals.
The sabkhas are covered by a salt crust, 3-5 cm thick, under which there lies 25-150 cm of carbonate sand, gypsum and halite.
