Fig. 13.25. a,b Conceptual models of basin-wide
fluid flow: a tectonically driven hot and highly saline, very slowly moving brine; b deep meteoric
flow. See text for further explanation. (After Heydari
1997, modified). c Regional, deep-burial dolomitization of Cambrian carbonate platform, south
Canadian Rocky Mountains, by long-distance fluid
flow. The pore fluids ascended along the platform
margin and penetrated into carbonate sheets causing
a second generation of massive dolomite. (After Yao
and Demicco 1997, modified). d Subsidence history
and diagenesis of Upper Triassie shallow-marine
limestones (Muschelkalk), southem Germany. The
limestones are underlain by evaporites. Most of the
strata studied were moderately buried and then exhumed, but a small portion has been deeply buried in
the Rhine graben where hydro thermal activity has
locally maintained high-temperature diagenesis.
