CANFIELDITE Meaning and
Definition
-
Canfieldite is a rare mineral that belongs to the sulfosalt group and is primarily composed of lead, tin, and sulfur. It is named after Dr. Frederick Alexander Canfield, an American mineralogist who made significant contributions to the field of crystallography. Canfieldite crystals are typically dark gray to black in color and have a metallic luster.
In terms of its chemical composition, canfieldite has the chemical formula Pb8Sn7Sb21S48 and a relatively high density. It often occurs as prismatic crystals or in granular form, embedded within other minerals such as sphalerite, galena, and tetrahedrite. Canfieldite is usually found in hydrothermal veins associated with tin and polymetallic sulfide deposits.
Due to its scarcity and limited occurrences, canfieldite is considered a collector's mineral and is highly valued among mineral enthusiasts. It has been found in a few locations worldwide, including Bolivia, Canada, and the Czech Republic.
In addition to its mineralogical significance, canfieldite has also attracted interest in metallurgy, especially in the extraction and refining of lead and tin. Researchers have investigated its crystal structure and properties, contributing to a deeper understanding of its applications in various industries.
Overall, canfieldite is a rare sulfosalt mineral prized for its unique composition and crystal habit, with notable significance in both mineralogical and metallurgical fields.
Etymology of CANFIELDITE
The word "canfieldite" is named after Frederick A. Canfield, an American mineralogist who discovered the mineral in 1889. The suffix "-ite" in mineralogy is commonly used to denote that the term refers to a specific mineral species or variety. Therefore, Canfieldite is named in honor of the scientist who first described it.
