WebConversion of clays and other unstable components releases H 2O (bound water – water contained in the clay mineral crystal structure),SiO 2, Mg2+ and Fe2+. This final release of water allows these components to migrate to other forma8ons where they are used in the diagenesis of other rocks. This expulsion of bound water also helps WebOther Related Research; Abstract. Understanding the processes and products of carbonate diagenesis is essential to exploration for, and optimum development of, hydrocarbon reservoirs in carbonate rocks. Much cementation and formation of secondary porosity in carbonates occurs at relatively shallow depths in one of four major diagenetic ...
