Definitions:

Unfractured Granite

A type of igneous rock, characterized by its large crystals and lack of cracks or fractures, often used in construction due to its strength.

Fine-Grained Sediment

Sediment that consists of tiny particles and fragments, such as clay or silt, which are often transported by water or wind and deposited in calm environments.

Permeability

Permeability is a measure of how easily a fluid can move through a porous material, such as soil or rock, indicating the material's ability to transmit water or other fluids.

Compacted Clay

Clay soil that has been compressed, often leading to reduced water infiltration and aeration.
