FAUSTITE Meaning and
Definition
-
Faustite is a mineral that belongs to the hydrous zinc aluminum phosphate group. It is named after the German mineralogist and chemist, Fausto Simonato, who discovered and described the mineral. Faustite is commonly found in the oxidation zone of zinc-bearing ore deposits, particularly associated with other zinc minerals.
The mineral is typically characterized by its vibrant green color, which can range from pale to dark green. It has a vitreous luster and can exhibit translucent to transparent properties. Faustite has a Mohs hardness ranging from 3 to 4, making it relatively soft. Its crystal structure is monoclinic, and it commonly forms in prismatic or tabular crystal habits.
In terms of its chemical composition, faustite is a complex phosphate mineral composed of zinc, aluminum, and phosphorus, with traces of other elements. Its chemical formula can be written as ZnAl6(PO4)4(OH)8·4H2O. The presence of water molecules in its structure contributes to its hydrous nature.
Faustite has limited economic importance and is primarily valued for its aesthetic properties. It is often sought after by collectors due to its distinctive green color and unique crystal habits. However, it is important to handle faustite with care, as it can be easily damaged or scratched due to its relative softness.
Etymology of FAUSTITE
The word "faustite" originates from the name of the German scholar, Johann Georg Faust (1480-1540), who was widely known for his alleged mastery in magic and alchemy. The term "faustite" was coined in the early 20th century to describe a mineral that was discovered in the Silverton mining district of Colorado, USA. This mineral was found to be a variety of green or blue-green rocks known as zinc-aluminum-phosphate-hydroxides. The name "faustite" was chosen due to its association with the mystical and magical connotations of Johann Georg Faust's name.
