Abstract
The volcanolithic sandstones average 35% core porosity and 125 md permeability. Micropores constitute the predominant pore-type in these rocks and, where macropores are present, they comprise both isolated primary intergranular and secondary grain-dissolution pores. The quartzose sandstone has 29% (mean) core porosity and 676 md (mean) permeability; and the pore-types are mainly primary intergranular pores, and accessory intragranular grain-dissolution pores (mostly within feldspar grains). -from Authors
