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

Figure 12

Calculated oxygen and hydrogen isotopic composition of the parent water that precipitated kaolinite and cogenetic calcite in the Muschelkalk (MK) and in the crystalline basement (CB) at the wells of Benken (BEN), Schlattingen (SLA), and Siblingen (SIB). Shown for comparison are the Local and Global Meteoric Water Lines, present-day precipitation, recent groundwater in the Muschelkalk and in the underlying crystalline basement, and Permocarboniferous and Buntsandstein within the NE-Swiss Molasse Basin. ¹[54], ²[55], ³[20], ⁴[38], ⁵this study.
