sandstone
Sedimentary rock, especially sandstone, is expected to have the greatest porosity due to its formation process involving the accumulation of loose grains that leave spaces between them where fluids can reside. This high porosity allows for the storage and movement of fluids such as water, oil, or gas within the rock.
Porosity refers to the percentage of open space between individual rock particles in a rock layer. This space can be between grains or within the cracks or cavities of the rock.
The volume of open pore spaces in a rock is known as its porosity. It represents the percentage of void space in the rock that can potentially hold fluids like water or oil. Porosity is an important characteristic in determining the suitability of a rock for storing or transmitting fluids.
Clay has higher porosity than solid rock. Porosity is a measure of the amount of pore space within a material, and clay typically has more interconnected pore spaces compared to solid rock, allowing for greater water and gas storage. Solid rock, being less porous, has fewer interconnected pore spaces, limiting its ability to store fluids.
Primary porosity: The initial pore space that forms in rocks during their formation. Secondary porosity: Pore space created by post-depositional processes like fracturing or dissolution. Effective porosity: The portion of the total porosity that allows fluid flow through the rock.
Porosity refers to the measure of how much of a rock is open space. The two factors concerning particles in a rock that have the greatest effect on the rock's porosity are shape and distribution.

The porosity of the rock is the most important factor in determining how much groundwater can be stored in underground rock. Porosity refers to the amount of empty space within the rock that can be filled with water. Rocks with high porosity can store more groundwater.
