What type of sedimentary rock is often associated with high porosity and permeability?

Sandstone is a type of sedimentary rock known for its high porosity and permeability. Porosity refers to the amount of open space within the rock that can hold fluids, while permeability is the ability of the rock to allow fluids to flow through it. Sandstones are formed from consolidated sand grains, which typically creates many interconnected pores between the grains. This structure enables sandstone to store significant amounts of water, oil, or gas, making it an important reservoir rock in various geological settings.

The composition and grain size of sandstone contribute to its hydrodynamic properties, enhancing both the flow of fluids through the rock and its capacity to retain those fluids. Commonly found in sedimentary basins, sandstone serves as a vital resource in hydrogeological studies and petroleum exploration due to these characteristics.
