What kind of rocks have high and low porosity and permeability?

High porosity and permeability are typically found in sedimentary rocks such as sandstone and limestone, which have interconnected pore spaces that allow fluids to flow easily. Conversely, igneous rocks like granite and metamorphic rocks such as schist generally have low porosity and permeability due to their dense, crystalline structures that lack significant pore spaces. The properties of rocks can significantly affect their ability to store and transmit fluids, making these characteristics important in fields like geology and petroleum engineering.
