gottlobite

Gottlobite, ), is a mineral in the adelite group found as isolated crystals or isometric grains of orange or orange-brown color. The size of the crystals are a half millimeter in diameter and are part of the orthorhombic crystal system. Gottlobite is the vanadate end member in a solid solution formed with adelite (). Gottlobite is also part of the vanadates and arsenates group. With these characteristics, it is similar to the minerals tangeite and austinite by X-ray diffraction methods.

==Occurrence== Gottlobite is a relatively rare mineral where only a small quantity of the mineral has been found. It was first observed at the site of a long-abandoned mine on the northern slope of Gottlob hill in Friedrichroda, Thuringia, Germany by Jὒrgen Graf in August of 1996. As such, gottlobite got its name from its locality. Additionally, the German translation of "Lob" means "praise" and the German translation of "Gott" means "God", as deciphered by Google Translate. In the mine at this location, Gottlobite is found in hydrothermal veins of barite that are cutting through conglomerate. The crystals of gottlobite can be found embedded in these barite veins or as stand-alone crystals on surrounding minerals. The associated minerals in the area are hausmannite, barite, vanadian adelite, and muscovite.
