Rhyolite is an igneous, volcanic rock that is composed of Felsic, or Silicate
minerals such as Silica, Aluminum, Sodium and Potassium. The material
is similar to that of Granite, Pumice and Obsidian but due to the cooling process
when formed, Rhyolite did not form any crystals, thus changing the texture of
the material.

Petrified Wood is a type of a fossil as it consists of fossil wood where
all the organic materials have been replaced with minerals while retaining the
original structure of the wood. These minerals are most often Silicates
such as Quartz. Other minerals, Manganese, Iron and Copper, in the water
or mud during the petrification process give Petrified Wood a variety of color
ranges: black - Carbon; green/blue - Copper; red/brown/yellow - Iron.
Petrified Wood can preserve the original structure of the wood in all its detail
all the way down to the microscopic level. Structures such as tree rings
and the various tissues are often observed features. Although Petrified
Wood can be found worldwide, it is rather rare in larger quantities and at times
can be difficult to obtain by the average collector.
