Abstract. We have conducted experiments on dissolution of quartz, albite, orthoclase, and corundum into H 2 O-saturated haplogranite melt at 800°C and 200 MPa over a duration of 120–1488 h with the aim of ascertaining the diffusive transport properties of granitic melts at crustal anatectic temperatures. Cylinders of anhydrous starting glass …
Albite is the last type of feldspar to crystallize from molten rock. During the final stages of the crystallization process, the rare elements are isolated together with the rare and beautiful minerals, and so does Albite. Even if it isn't a one-of-a-kind mineral, Albite can be a great accessory mineral to other kinds of minerals.
Albite belongs to the Plagioclase Feldspar group, an isomorphous solid solution series.Albite is one end member, containing sodium and no calcium. The other end member, Anorthite, contains calcium and no sodium.The intermediary members are Oligoclase, Andesine, Labradorite, and Bytownite.Oligoclase and Andesine are …

The term phase refers to any compositionally and physically distinctive substance. Phases may be solids, liquids or gases. Phase equilibria involve chemical reactions when one or more phases react to form different …
Albite is a very common mineral, but localities where fine Albite crystals can be found are more limited. Some excellent examples have come from the Swiss Alps and the Tyrol, Austria. Large, well formed crystals come from the pegmatite s of Gilgit, Pakistan; and Nuristan, Afghanistan.
Is Albite rare? Albite is a very common mineral and is a significant rock-framing mineral. It requires a longer time for Albite to solidify than different feldspars. …

The spot RI readings around 1.52 were consistent with albite's published RI of 1.528–1.542. The SG of albite is 2.60–2.65, considerably lower than that of jadeite. The presence of albite as a major mineral component in this material could account for the much lower SG in most of the samples.

Twinning is important to recognize, because when it occurs, it is often one of the most diagnostic features enabling identification of the mineral. What happens is that lattice points in one crystal are shared as lattice points in another crystal adding apparent symmetry to the crystal pairs. ... called the Albite Twin Law, with {010} as the ...
