Calcareous ooze lithifies as lime mudstone, sometimes referred to as pelagic limestone. Below the CCD, only dust and silica can deposit, as the calcareous organisms dissolve before reaching the sea floor, and siliceous ooze accumulates more quickly than red clays. Lime mud never comes in contact with the pulp bleaching portion of the 27 mill. 28 29 The petition indicates that small quantities of calcium hydroxide may be present. 30 31 Calcium carbonate is a natural component of soils.

Above 100 kPa, the Blue Lias, Charmouth Mudstone, Scunthorpe Mudstone, and Whitby Mudstone Formations are very closely grouped. The results place the Lias Group in the ‘medium’ cv class, typical of medium plasticity soils, with the exception of the Dyrham which is placed in the ‘high’ category, typical of low plasticity, more permeable soils (e.g. silts) …

Lime Mud Deposits? Shallow-water lime muds in today's tropical oceans accumulate at a rate of one foot thickness per one thousand years. These muds are formed by mechanical breakdown of carbonate containing sea creatures. Modern muds are believed by evolutionists to provide an excellent example of how ancient lime mudstones ("micritic limestones") were accumulated in Grand Canyon.
