Superstition Mountains Geology
The Superstition Mountains are actually the result of intensive volcanic activity. They are composed of welded tuff (volcanic ash cemented under extreme heat), breccia (rock fragments cemented together with lava or welded tuff), granite, dacite, basalt, and some conglomerate.

Are all mountains dormant volcanoes?
Volcanoes may be hill to mountain size. However, not all hills and mountains are volcanoes. Some are tectonic features, constructed by mountain building , which often happens at plate boundaries, just like volcanism. Others are erosional features, leftovers from earlier tectonic mountains.
What are the warning signs of a volcanic eruption?
How can we tell when a volcano will erupt?
- An increase in the frequency and intensity of felt earthquakes.
- Noticeable steaming or fumarolic activity and new or enlarged areas of hot ground.
- Subtle swelling of the ground surface.
- Small changes in heat flow.
- Changes in the composition or relative abundances of fumarolic gases.
How do we know if a volcano is about to erupt?
Another way of finding out when a volcano is about to erupt is by measuring the gases escaping from it. This is because when magma moves towards the surface, gas escapes and rushes out ahead of the magma. These gases can be measured from space or on the ground.
What is the difference between an ordinary mountain and a volcano?
Mountains and Volcanoes are somewhat similar but the major factor that makes them different is their formation.
