Study Notes
Paraconformity
- A type of unconformity where the bedding planes above and below the unconformity are parallel.
- Indicates a period of non-deposition, resulting in a time gap.
- Characterized by a faunal break, but no weathering.
Applications of Stratigraphy
- Geological mapping: Identifying and correlating rock layers to create maps.
- Oil and gas exploration: Locating and predicting the distribution of reservoir rocks.
- Paleoclimatology: Reconstructing past climates based on sedimentary records.
- Archaeology: Establishing the chronology of human activities.
- Engineering geology: Assessing site suitability for construction projects.
Stratigraphic Units
- Building blocks of stratigraphy, defined by unique properties.
Lithostratigraphic Units
- Based on rock type and physical characteristics.
- Fundamental unit: Formation.
Chronostratigraphic Units
- Based on relative or absolute age.
- Fundamental unit: System.
Biostratigraphic Units
- Defined by fossil content.
- Fundamental unit: Biozone.
