- 7 Principles of Geology
- 1- Principle of Uniformitarianism
- Geological processes which have
modified the crust now have woked
in the same way over geological time
- Geological processes which have
modified the crust now have woked
in the same way over geological time
- 2-Principle of Intrusive relationships
- When an igneous rocks cuts into a
formation of sedimentary rocks it
(intrusion)can be determined that
the intrusion is younger than the
sedimentary rocks
- When an igneous rocks cuts into a
formation of sedimentary rocks it
(intrusion)can be determined that
the intrusion is younger than the
sedimentary rocks
- 3- Principle of cross cutting relationships
- Faults are younger than the
rocks they cut
- Faults are younger than the
rocks they cut
- 4- Principle of inclusion and components
- If Sedimentary inclusions are found
in a formation it must be older than
the formation that contains them
- If Sedimentary inclusions are found
in a formation it must be older than
the formation that contains them
- 5- Principle of original horizontality
- States that deposition of
sediments occour as horizontal
beds
- States that deposition of
sediments occour as horizontal
beds
- 6- The principle of superposition
- States that a sedimentary layer of
rock, in a tectonically undisturbed area
is younger than the one beneath it
- States that a sedimentary layer of
rock, in a tectonically undisturbed area
is younger than the one beneath it
- 7- The principle of faunal succession
- Is based on the appearance of fossils in a
sedimentary rocks, this can provide a relative age
for the formation
