Stratigraphic formation.
The classification of lithofacies is an important component of petrophysical formation evaluation and reservoir characterization. Lithofacies are a subdivision of any stratigraphic unit that has characteristic lithologic features (Carannante et al., 1988), or a combination of lithology and depositional facies (Ngui et al., 2018).Different lithofacies also have distinct petrophysical properties ...
Deposition began about 75 million years ago with the formation of the Pierre Shale, the base of the geologic formations in the park.
