Experimental investigation of calcium carbonate mineralogy in past and future oceans [PDF]
, 2011 Inorganic marine calcium carbonate formation and mineralogy varies significantly concurrent with the solution composition. During the Phanerozoic, due to oscillations in the seawater composition, this resulted in the formation of either dominantly ...

Biotic and Abiotic Controls on Calcium Carbonate Formation in Soils [PDF]
, 2010 Over half of the carbon (C) taking part in the global C cycle is held in terrestrial systems. Because of the sensitivity of the C cycle to changes in such soil-based pools of carbon, it is important to understand the basic mechanisms by which soil C is

Calcium carbonate-calcium phosphate mixed cement compositions for bone reconstruction [PDF]
, 2006 The feasibility of making calcium carbonate-calcium phosphate (CaCO3-CaP) mixed cements, comprising at least 40 % (w/w) CaCO3 in the dry powder ingredients, has been demonstrated.

Calcium Carbonate Suppresses Haem Toxicity Markers without Calcium Phosphate Side Effect on Colon Carcinogenesis [PDF]
, 2010 Red meat intake is associated with increased risk of colorectal cancer. We have previously shown that haemin, haemoglobin and red meat promote carcinogen-induced preneoplastic lesions, aberrant crypt foci, in the colon of rats.

A study of calcium carbonate formation in biological systems [PDF]
, 1983 This thesis has studied aspects of biomineralisation, covering the inorganic mineral, the organic matrix, the possible use of phospholipid bilayer vesicles to control mineralisation, calcium and other metal binding to an antibiotic ionophore, Lasalocid-A
