Along with gem spodumene and tourmaline, Jahns and Wright (1951) list quartz, perthitic microdine, albite, beryl (morganite and aquamarine), bavenite, bertrandite, numerous bismuth-containing minerals including native bismuth, bismuthialte, bismutite, and bismite, and nurnerous phosphates including lithiophilite, triphylite, sickletite, purpurite, heterosite, stewartite, and hureaulite.
Numerous other phosphates also occur in the pegmatite as alteration products of primary lithiophilite. These include sicklerite, purpurite, hureaulite, phosphosiderite, strengite, stewartite, eosphorite, robertsite, mitridatite, jahnsite, fairfieldite, hopeite, and pseudomalachite.
Some specimens were heavily manganese stained, possibly by the decomposition of locally abundant primary phosphates such as lithiophilite. In all, several hundred specimens were collected from the pocket (B.
The mine has produced an interesting suite of minerals in recent years, including pale blue to green aquamarine, alpine-like smoky quartz crystals, spessartine, danburite, columbite, cassiterite, helvite, and numerous phosphates including apatite, lithiophilite, purpurite, herderite, strengite, phosphosiderite, hureaulite, robertsite, eosphorite, frondelite and mitridatite (A.
Lithiophilite is the major constituent of the phosphate pods.
Triplite occurs sparingly as dark brown, waxy grains and patches associated with lithiophilite and triploidite in some of the pods.
At the Boqueiraozinho pegmatite triploidite occurs as elongated, subparallel, prismatic, pinkish red crystals up to 8 cm in length within some of the lithiophilite. The crystals have a brilliant luster and the smaller ones are nearly transparent.
One specimen composed chiefly of lithiophilite and triploidite contains rare, minute grains of a vitreous, green, unidentified mineral.
