Sedimentary rocks are Secondary Minerals,

Metamorphic rocks are Tertiary Minerals.

This crystal, found in a river in China, has an interesting history. It started life as a clear quartz cluster, but over time became submerged in river silts. Eventually the crystal was completely transformed as the sediments infiltrated the molecular lattice, and replaced the pure silicates with river sediments.

This Sediment Quartz, now has the texture of jasper, but has retained its quartz crystal appearance.

The diagram below represents the various transformations that rock will experience long after its igneous birth. On the clockwise turn rocks are undergoing changes related to environmental forces.  On the anti – clockwise turn rocks undergo changes brought about by heat and high pressures.   Metamorphic rocks can become sedimentary and vice-versa.  Eventually all rock returns to the magma below via subduction. At the same time new rocks…
