Morrow points out that our model is “significantly different from prevailing views . . .” Indeed, the fundamental strength of the new dolomitization paradigm we present in MC-2011 is that – based on two postulates – it predicts a multitude of associated properties of burial dolostones that are independently confirmed by observations. The first postulate is that dolomitizing brines must be Mg-rich but undersaturated with respect to both calcite and dolomite. According to the second postulate, replacement, a phenomenon dominant in dolomitization and all other types of metasomatism, happens not by “dissolution-precipitation” as assumed by geochemists since the 1960s, but by precipitation/pressure-dissolution within a rigid rock via the induced stress. To summarize: the new paradigm differs from prevailing views in that (a) it proceeds forward from the two basic postulates; (b) both postulates are contrary to prevailing wisdom; (c) it involves no ad-hoc assumptions; (d) it includes feedbacks – especially a crucial self-accelerating feedback – ignored by traditional models; and finally, as noted, (e) it makes “a multitude of associated predictions” – lithological, paragenetic, textural, rheological, geochemical, petrophysical – which are independently confirmed by observations.
