metatorbernite
Metatorbernite (or meta-torbernite) is a radioactive phosphate mineral, and is a dehydration pseudomorph of torbernite. Chemically, it is a copper uranyl phosphate and usually occurs in the form of green platy deposits. It can form by direct deposition from a supersaturated solution, which produces true crystalline metatorbernite, with a dark green colour, translucent diaphaneity, and vitreous lustre. However, more commonly, it is formed by the dehydration of torbernite, which causes internal stress and breakage within the crystal lattice, resulting in crystals composed of microscopic powder h
manganvesuvianite
Manganvesuvianite is a rare mineral with formula . The mineral is red to nearly black in color. Discovered in South Africa and described in 2002, it was so named for the prevalence of manganese in its composition and its relation to vesuvianite.
metazeunerite
Metazeunerite is an arsenate mineral with a chemical formula of Cu(UO2)2(AsO4)2·8H2O. The origin of this mineral is almost always from the natural dehydration process of zeunerite.
rosenbergite
Rosenbergite is a mineral with the chemical formula AlF3·3H2O. It is a trihydrate of aluminium fluoride.
mathesiusite
Mathesiusite is a sulfate mineral containing potassium, vanadium, and uranium and has the chemical formula: K5(UO2)4(SO4)4(VO5)·4(H2O). It is a secondary mineral formed during post-mining processes.
