MITSCHERLICHITE Meaning and
Definition
-
Mitscherlichite is a mineral that belongs to the group of sulfates. Its chemical formula is K2Cu2(SO4)2(OH)2 · 6H2O, expressing its composition of potassium, copper, sulfate, water, and hydroxyl. This mineral was initially discovered in the 19th century and was named after Eilhard Mitscherlich, a notable German chemist and mineralogist.
Mitscherlichite is typically found in oxidized copper ore deposits, specifically in the oxidation zone close to the ground surface. It forms as a secondary mineral through the weathering of primary copper sulfides, such as chalcopyrite and bornite. The occurrence of mitscherlichite is often associated with other secondary copper minerals, including brochantite and chrysocolla.
Visually, mitscherlichite appears in the form of tabular or prismatic crystals, which possess a green to blue-green color. These crystals are generally translucent and have a vitreous luster. It may also occur in an acicular or fibrous habit. Mitscherlichite is characterized by its monoclinic crystal system and possesses good cleavage along its faces.
Due to its unique composition, mitscherlichite serves as an important source of copper. However, its low abundance and lack of widespread occurrence restrict its practical significance as a copper ore. Mitscherlichite is primarily appreciated by mineral collectors and researchers for its aesthetic value, as it is often sought after for its sharp crystal formations and vibrant colors.
Etymology of MITSCHERLICHITE
The word "mitscherlichite" is derived from the name of Eilhard Mitscherlich, a German chemist who lived in the 19th century. He made significant contributions to the field of crystallography and mineralogy. Mitscherlichite is a mineral named in his honor, originally discovered in 1869 by the Austrian mineralogist Gustav Tschermak.
