Abstract Ancient limestone-marl alternations are concentrated in settings analogous to loci of aragonite accumulation in the modern world. They typically occur on shelves in the tropical-subtropical climate belt, are far more abundant on passive continental margins than on active ones, and are rare in upwelling zones.

Marls are generally compacted and cleaved and also show some hard substrate at places. Marly limestone is general- ly light grey to medium grey and thin bedded to medium bedded with occasional thick beds. It is generally unfossiliferous and contains some burrows which are identified as Thalssinoids of Cruzania class (Figure 3(d)).

网页Limestone is a sedimentary rock which is mainly made up of calcium carbonate. Marl 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.
