5 Questions
Correlation is a representation of an actual column of rock drawn to show rock type, thickness, deformation, inclusions, and used for correlation across geographic areas.
True
A supergroup may include formations and has significant features in common.
True
Chronostratigraphic units are based on physical characteristics and may not be the same age everywhere they are found.
True
A formation is a laterally continuous rock unit with a distinctive set of characteristics that make it possible to recognize and map from one outcrop (or well) to another.
True
Lithostratigraphic units are the actual rocks deposited during a specific time period.
False
Study Notes
Correlation and Rock Units
- Correlation is a visual representation of a rock column, showcasing rock type, thickness, deformation, and inclusions to facilitate correlation across different geographic areas.
Types of Rock Units
- A supergroup is a collection of formations that share significant features in common.
- A formation is a laterally continuous rock unit with a unique set of characteristics, making it identifiable and mappable from one outcrop or well to another.
- Lithostratigraphic units are the actual rocks deposited during a specific time period.
- Chronostratigraphic units are defined by physical characteristics, but may not be the same age everywhere they are found.
