Here we have an old-time specimen from Pakistan, mined in the 1980s, when the Russians were fighting in Afghanistan. It was purchased by Rich Kosnar from noted mineral dealer Rick Smith, who was one of the first western dealers to travel to the area and bring home gem pegmatite minerals.
Triphylite describes both a mineral series, as well as an individual mineral within the series. Triphylite is the iron-rich end member of the Triphylite series, and Lithiophilite is the manganese-rich end member. Minerals of the Triphylite series commonly alter to secondary phosphates such as Vivianite, as well as to manganese and iron oxides.
Lepidolite is a pink to purple mica and the most common lithium-bearing mineral. It is a minor ore of lithium. When impregnated with quartz, lepidolite-bearing rocks are sometimes used as ornamental stone or as gem materials.

This beautiful matrix tourmaline specimen from California's famous Himalaya mine features a gemmy, bright-pink, well-terminated ~3.3 cm. rubellite crystal emerging from a matrix of cleavelandite albite.
Introduction: albite is the sodic end-member of the plagioclase feldspar series. It is present commonly in acid intrusive and eruptive igneous rocks such as granites and rhyolites, and is also a characteristic mineral in low-grade metamorphic rocks particularly those derived from basic igneous precursors.
The albite content in two selected sam-ples was high (65–40 wt. %), accompanied by quartz (25–40 wt. %) and other minor minerals iden-tified by XRD, mainly kaolinite, in agreement with the high content of silica and alumina deter-mined by XRF. The content of Na2O was in the range 5.44–3.09 wt. %, being associated with albite.

In favorable circumstances, what would otherwise be gangue minerals (quartz, potassium feldspar, albite, and muscovite) can be mined along with lithium and (or) tantalum as coproducts.

The plagioclase feldspar minerals are albite, oligoclase, andesine, labradorite, bytownite and anorthite. They are common rock-forming minerals and occasionally gem materials …
Albite is a very common mineral, and is an important rock-forming mineral. It takes a longer time for Albite to crystallize than the other feldspars. This enables Albite to form in large and well crystallized examples. Albite is also a common accessory mineral to …
Hematite is the most important ore of iron.Although it was once mined at thousands of locations around the world, today almost all of the production comes from a few dozen large deposits where significant equipment investments allow companies to efficiently mine and process the ore.

Many Bancroft Area minerals are classics. Although fine specimens from the Bancroft Area are uncommon on the international market, they can still be field collected. Bancroft mineral collecting continues each year and it is beautiful in the fall. I thought you might like some glimpses of our fall, scenes, wildlife and recent mineral collecting in the Bancroft Area.
Plagioclase minerals are hard, non-metallic minerals that exhibit two cleavage directions that meet at nearly right angles. The name 'plagioclase' refers to this cleavage pattern, coming from the Greek words for 'oblique' (plagios) and 'to break' (klasis).Apart from pegmatites, the plagioclase minerals seldom occur as well-defined isolated crystals, but …
