BIXBYITE Meaning and
Definition
-
Bixbyite is a mineral that occurs naturally as a rare oxide of manganese. It belongs to the oxide mineral group and has a chemical formula of Mn2O3. The name "bixbyite" originates from the prominent American mineralogist Maynard Bixby, who first discovered and described this mineral in the late 19th century.
Bixbyite usually forms as black, lustrous, octahedral crystals, but it can also occur as granular or massive aggregates. Its crystal structure is cubic, and it has a high hardness level, typically ranging from 6.5 to 7.5 on the Mohs scale, making it relatively durable and resistant to scratching.
This mineral is primarily found in hydrothermal ore deposits associated with other manganese minerals and often occurs in close proximity to other minerals like hausmannite and manganite. It is commonly found in various locations around the world, including the United States, Russia, South Africa, and Brazil.
Bixbyite is widely recognized for its striking appearance and is occasionally used as a gemstone due to its excellent luster and deep black color. However, its scarcity and relatively small crystal sizes limit its use in jewelry. It is mainly sought after by mineral collectors who appreciate its distinctive crystal form and rarity.
In summary, bixbyite is a rare oxide mineral composed of manganese and oxygen. It typically appears as black, octahedral crystals and is known for its excellent luster. While its practical applications are limited, it is highly valued by collectors for its uniqueness and aesthetic appeal.
Etymology of BIXBYITE
The word "bixbyite" derives its name from the American mineralogist Maynard Bixby (1853–1935). Bixby discovered the mineral, bixbyite, in 1897 in the Thomas Mountains of Utah, United States. The mineral was named after him to honor his contributions to the field of mineralogy.
