It was a large piece rectangular rock, possibly lepidolite, carved with strange, flowing markings. |
It never occurs as a free element, but is found in minerals such as spodumene, petalite, and lepidolite. |
Its most common ores are lepidolite, carnallite, and pollucite. |
Morganite and quartz crystals are sometimes found within balls of fine-grained lepidolite within the pockets. |
Gases penetrating rock crevices allow the slow formation of lepidolite, topaz and tourmaline. |
Purple lepidolite and gray spodumene also can be found, and microcrystals of mangano-columbite are common. |
