Summary:The morphology, mineralogy and geochemistry of diagenetic carbonate concretions are discussed with distribution of intergranular diagenetic cements, the history of pore-water evolution, qualitative descriptions of processes and quantitative genetic models for concretion formation by sulphate reduction. The Jet Rock (Lias) of Yorkshire provides an example of the last- named. Siderites formed by other processes include Coal Measures siderite (Westphalian), from Hepworth, Yorkshire. The mainly microbial degradation of organic matter during burial produces inorganic species which may form carbonate and sulphide minerals, and can be characterized by stable isotope and chemical composition.
