Study Notes
Lithostratigraphy
- A lithostratigraphic unit is primarily based on rock type and its physical characteristics.
- Formations are the fundamental lithostratigraphic units, representing distinct rock bodies with unique lithological features.
- Members are subdivisions within formations, characterized by a specific rock type or internal structure.
- Supergroups are the largest lithostratigraphic units, comprising multiple formations and groups that share similar lithological and stratigraphic characteristics.
Chronostratigraphy
- Chronostratigraphic units are based on age, reflecting specific intervals of geological time.
- The primary basis for defining chronostratigraphic units is fossil evidence and radiometric dating, which help establish the relative and absolute age of rock layers.
- Lithostratigraphic units are based on rock type and physical characteristics, while chronostratigraphic units focus on the age of rocks.
