Unconformity

The contact zone between unlike strata groups, marking a historical period of erosive activity or absence of sediment deposition.

Permeable Units

Layers of earth materials, such as sand or gravel, that allow water to pass through easily.

Impermeable Units

Impermeable units refer to layers of rock or sediment that water cannot easily pass through, significantly affecting the flow of groundwater and the storage of hydrocarbons.
