Creation of Secondary Porosity in Dolostones by Upwelling Basement Water in the Foreland of the Alpine Orogen

Figure 10

Microthermometric results from primary fluid inclusions in secondary minerals from the Muschelkalk and the crystalline basement at various wells across the Swiss Molasse Basin. (a) Homogenization temperatures (). For the data from Mullis [43] and for saddle dolomites, the values correspond to minimum temperatures of fluid trapping. For all other data, corresponds to the exact trapping temperature (see text for explanation). Maximum rock temperatures during Cretaceous and Miocene maximum burial (Figure 2) are plotted for comparison. (b) Salinities calculated from ice-melting temperatures.
