- Igneous
- Forming
- Intrusive
- Cooling of magma
underground slowly
- Extrusive
- Cooling of Magma in the
air outside of a volcano quickley
- Features
- Has Holes
- Examples
- Sedimentary
- Metamorphic
- Formed for Igneous or
Sedimentary through heat or
pressure
- Crystals
- Large
- From over a long period
of time
- Small
- Forming over a short
period of time
- Stratagraphic formations
- Intrusions
- Nonconformity
- Where metamorphic rocks get piled
with layers of sediment
- Disconformity
- Sequence of sedimentary rocks which
form an intrusion over it with more
sediments
- Angular
Unconformity
- Where a tilted layer of sedimentary rock get
piled with more sedimentary rocks
- Inclusions
- A solid, liquid or gaseous
foriegn body enclosed in a
mineral or rock
- Faults
- Transform Faults
- When rocks move
sideways along
eachother
- Normal Fault
- Where rocks rubb against
eachother up and down and
away from eachother
- Reverse Faults
- Rubbed against each
other diagonally
- 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
- 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
- 3- Principle of cross cutting relationships
- 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
- 5- Principle of original horizontality
- 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
- 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
- Folding
- Anticline
- Rock folded up
- Sincline
- Rock folded down
