Descriptions of color and composition vary widely because often the descriptions are either state wide summaries or of particular localities. The Geology of Texas Volume 1, Stratigraphy by Sellards, Adkins, and Plummer describe the Ozan as a dark gray marl.
Chalk is formed from lime mud, which accumulates on the sea floor in the right conditions. This is then transformed into rock by geological processes: as more sediment builds up on top, and as the sea floor subsides, the lime mud is subjected to heat and pressure which removes the water and compacts the sediment into rock.Note that the Lower Chalk has been placed by Rowe entirely in the subglobosus zone. The plenus marl at the top of the Lower Chalk has been displaced northwards by a small thrust fault. LOCATION: Durdle Cove - ……

Embry has modified Dunham's classification and Klovan (1971) to include coarse grained carbonate s (above figure). In their revised scheme, a wackestone in which the grains are greater than 2mm in size is termed a floatstone and a coarse grainstone is called a rudstone. Both terms are extremely useful in description of limestone s.There are various physical properties of Chalk like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it.
