What are the stratigraphic principles?

There are 6 of these...

Law of Superposition

The geologic principle that states that in horizontal layers of sedimentary rock, each layer is older than the layer above it and younger than the layer below it.

Principle of Original Horizontality

The geologic principle that states that sediments are deposited as essentially horizontal beds.

Principle of Lateral Continuity

The geologic principle that states that strata originally extended in all directions until it thinned out to zero or ended against the edges of another structure or deposit.

Principle of Cross-cutting Discontinuities

The geologic principle that states that any discontinuity that cuts across a stratum must have formed after that stratum.

Law of Inclusions

The geologic principle that states that any piece of rock that has become included in another rock or body of sediment must be older than the rock or sediment into which it has been incorporated.

Law of Faunal Succession

The geologic principle that states that sedimentary rocks that contain fossils succeed each other in specific and reliable order.
