This rock contains the minerals quartz, biotite, schorl and muscovite. These minerals are imbedded in granite pegmatite. This could be known as tourmaline pegmatite and is an igneous rock.
Mica and quartz/ igneous rock
This rock is an interesting example of mica and quartz together. This is an igneous rock.
Whit feldspar and hornblende
This group of rocks is made up of white feldspar and the black is hornblende. Hornblende is often found in igneous rocks like granite.
Schorl with red garnets
Look closely and you will find the red garnet imbedded in this piece of schorl! This is a small sample! *HINT* Click on the image to make it larger!
Quartz crystals
Embedded in this piece of feldspar are many quartz crystals.
White granite
White granite is usually made up of feldspar, biotite mica, hornblende and muscovite.Granite can also be pink or dark grey. These are igneous rocks.
Schorl
The rock pictured to the left contains this mineral. It is black tourmaline also known as schorl.
Muscovite
This mineral is mica, also known as muscovite. It can be peeled apart in thin layers. It is found mixed with many of Maine's igneous rocks and gives them a "sparkly" look.
Golden beryl
This mineral is golden beryl. Beryl can also be pink, aquamarine, yellow green and white.
Red garnet with white feldspar
This group contains two types of minerals. I pictured them together to see the red garnet easily against the white of the feldspar.
Brown topaz
Pictured above is brown topaz. Topaz can also be white, colorless, gray, yellow, orange, blue, purple and pink.
Clear quartz/ milky quartz
Pictured above are 2 samples of quartz. The one on the left is a clear "crystal" quality and the one on the right shows more of the "milky" look quartz can have.
Smokey quartz crystal
Take a look at the grey color in this quartz crystal. This is called smokey quartz.Quartz can also be red, purple, pink, yellow, green, brown and black. Purple-violet quartz is known as the semi-precious gemstone amethyst.
