These crystals were abundant in a very micaceous pegmatitic rock composed of muscovite, albite, and quartz with accessory schorl crystals. |
|
During the formation of pockets, schorl was the dominant early tourmaline species forming and is found along the margins of the pockets. |
|
Here it was associated with quartz, albite, schorl, muscovite, and microcline in the intermediate zone. |
|
Sprays of black schorl in quartz are some of its most sought-after minerals. |
|
Most have some collectible minerals such as beryl, garnet, and schorl, and a few have lithium minerals. |
|
Garnets and schorl are the most likely collectible minerals to be encountered. |
|
They contain sulfide minerals as well as metamorphic minerals that include cordierite, gahnite, epidote, garnet, amphiboles, schorl, and many others. |
|
Brandberg has been producing thousands of gemmy, zoned amethyst crystals, and a new area was found in the Erongo Mountains for schorl, aquamarine, and topaz. |
