KOETTIGITE Meaning and
Definition
-
Koettigite is a mineral that belongs to the group of complex arsenates known as the vivianite group. It is named after Julius Ferdinand Koettig, a German mineralogist. Koettigite typically occurs as fine crystals and is recognized for its vibrant green to yellow-green coloration. The mineral has a monoclinic crystal system and possesses a prismatic habit, often forming radial or fibrous aggregates.
Chemically, koettigite is a hydrous copper zinc arsenate sulfate with the chemical formula Zn2Cu(AsO4)(SO4)(OH)·6H2O. It occurs as secondary mineral formations in oxidized ore deposits and often associates with other arsenic and copper minerals. The unique green color of koettigite is attributed to the presence of copper in its atomic structure.
In terms of physical properties, koettigite exhibits perfect cleavage on {010} and has a light green streak. It has a moderate to high specific gravity (density) of about 3.39, indicating its relatively high mass. Koettigite is non-fluorescent under ultraviolet light and is insoluble in water. It is also quite fragile and exhibits a brittle tenacity.
Koettigite is primarily sought after by mineral collectors due to its vivid green color and crystal beauty. Its presence in oxidized ore deposits can provide valuable insights into the mineralogical composition and formation processes of these geological environments. However, it should be handled with care as it contains toxic elements such as arsenic.

Etymology of KOETTIGITE
The word "koettigite" originated from the mineral’s discovery in the 19th century and was named in honor of German mineralogist Dr. Friedrich August Koettig. Dr. Koettig (1794-1868) was a renowned researcher and professor of mineralogy at the University of Freiberg in Saxony, Germany. His contributions to the field earned him recognition, and to commemorate his work, this mineral was named after him.
