SPLATS about geological structures
Principles about geological structures
- If a body of rock is subjected to enough force, it will break and slip along a plane of weakness, the process that we call geological faulting.
- Some faults have developed as a result of two tectonic plates moving past each other. These faults are earthquake zones: an example is the San Andreas fault.
- Most modern geological structures are the result of past tectonic activity which applies force to the world's rocks.
- Finding most types of mineral deposits depends on being able to envisage the structures which lie under the planet's surface.
- Geological structures can be economically important. Oil and gas are often found in anticlines or salt domes, and other structures can indicate mineralization.
- Some minerals are found near certain geological structures, usually indicating something of the way in which the deposits were formed at some time in the past.
- Given suitable pressure and force, apparently solid rocks can fold into complicated structures without breaking. This can happen on a small or large scale.
