WebFeb 24, 2024 · The red color of marls can be due to the presence of ferric iron in the marl composition. The presence of red indicates oxidizing conditions in the sedimentary environment. The alternation of red marl with gypsum and anhydrite suggests the sedimentation of this facies in shallow lagoon environments (Fig. 5).

Marl – Geology is the Way
WebMarl forms when very fine-grained clay particles are deposited in water which settles at the bottom of water bodies and are compacted by overlying sediment; the water squeezes out and hence forming Marl rock. 1.2 Composition 1.2.1 Mineral Content Calcite, Clay, Dolomite, Gypsum, Micas, Pyrite, Quartz 1.2.2 Compound Content WebMarl is regularly used to explain carbonate-rich tender mudstones. Texture: Clastic Sedimentary Rock Grain size: Very fine-grained (< 0.06mm); clasts not visible to the naked eye. Hardness: Generally quite soft, but can be hard and brittle.
