• Limestone and dolomite

     · Limestone and dolomite have been formed in a variety of settings in Victoria and range in age from early Palaeozoic to Quaternary. Younger limestones tend to be friable and porous, whereas older limestones are often dolomitised and silicified, or metamorphosed and recrystallised to marble.

    While limestone cores showed the least formation damage from iron precipitation, coreflood tests indicated that as the iron concentration increases, the damage was more evident. On the other hand, increasing the temperature adversely affected sandstone and dolomite cores, but improved the final permeability of limestone cores.
