  1. Its the rock cycle:

    igneous gets eroded into sediment then hardened into sedimentary rocks....then its buried eventually heated and cooked until it becomes metamorphic, then it gets too heated and cooked and then becomes magma and soon igneous again.....

    the best way to show this graphically would be with arrows and labels like the link below

  2. An ingenous rock is laying on the ground in a hollow.  Snow accumulates over hundreds of centuries.  The glacier that is formed is heavy.  As the glacier melts, the rocks below are crushed.  As the thaw progresses, the bands of this crushed rock can be seen in photos of glaciers.  When the glacier receeds, the sediment is exposed to elements and now sedimentary rocks have been formed.  

    As to turning back to Ingenious, well reverse the process, numerous sediment rocks are shifted and twisted by earthquakes, volcanoes,  and again they are mixed in with other types of rocks, they are left alone for hundreds of centuries and they again become a component of ingenious neighbors.

    Another example of metamorphic rocks.  I have been studying about Onyx versus Blackstone.  Blackstone is a jasper, a kissing Quartz cousin of Onyx.  But metamorphicly Jasper can become agate.  

    Here is one of the hundreds of theories on thunder eggs.  They are particles of rock (a Blackstone jasper as an example)  The particle is coated in lava during an eruption, and thrown miles around the volcano.  Due to the high temperature, the elements in this jasper (a quartz family)  now separates, and solidifies.  So years later we now have a piece of black banded agate. (Still in the quartz family)

    Today on the market, Onyx is very fashionable.   Much of the Onyx is actually died Chalcedony, which is the same thing, just a different color, easily dyed in quanity and does not leave the banded variations that much of the older Onyx has.

    Much of the Blackstone being sold is actually this dyed Chalcedony.  It is not a lie because most agate is dyed.  And Chalcedony is actually the pale clear color that is between the bands, and many times the center of a geode is solid with this light pale agate.  Rule of thumb on agate.  Any agate that has this pale banding has not been dyed because it would not be that color if any color enhancing has happened.
