Chabazite is a tectosilicate mineral of the zeolite group, closely related to gmelinite, with formula (Ca,Na2,K2,Mg)Al2Si4O12·6H2O. Recognized varieties include Chabazite-Ca, Chabazite-K, Chabazite-Na, and Chabazite-Sr, depending on the prominence of the indicated cation.

Shattuckite is a copper silicate hydroxide mineral with formula Cu5(SiO3)4(OH)2. It crystallizes in the orthorhombic - dipyramidal crystal system and usually occurs in a granular massive form and also as fibrous acicular crystals. It is closely allied to plancheite in structure and appearance.

Studtite, chemical formula ((UO2)O2(H2O)2)·2(H2O) or UO4·4(H2O), is a secondary uranium mineral containing peroxide formed by the alpha-radiolysis of water during formation. It occurs as pale yellow to white needle-like crystals often in acicular, white sprays.

Apachite is a copper silicate mineral with a general formula of Cu9Si10O29·11H2O. The name is associated with the Apache tribe residents of the area near the Christmas copper mine in the Dripping Spring Mountains of Gila County, Arizona, the location where apachite was first described in 1980.

Kolbeckite (scandium phosphate dihydrate) is a mineral with formula: ScPO4·2H2O. It was discovered originally at Schmiedeberg, Saxony, Germany in 1926 and is named after Friedrich L. W. Kolbeck, a German mineralogist. Kolbeckite is usually found as small clusters of crystals associated with other phosphate minerals.

Amakinite is a semi transparent yellow-green mineral belonging to the Brucite group that was discovered in 1962. Its chemical formula is written as (Fe2+,Mg)(OH)2. It usually occurs in the form of splotchy, anhedral crystals forming within a group or structure in other minerals or rocks. Its composition is as follows:

Tungstite is a hydrous tungsten oxide mineral with formula: WO3·H2O. It is a secondary mineral formed by the weathering of other tungsten containing minerals. It crystallizes in the orthorhombic system in translucent yellow to yellow green masses. It is clay-like with Mohs hardness of 2.5 and a specific gravity of 5.5.

Kainosite is a silicate mineral that has the formula of Ca2(Y,Ce) SiO4O12(CO3)•(H2O). Kainosite was first discovered in Norway on the island of Hitterø and was named by Adolf Erik Nordenskiöld (1832-1901) in allusion to the Greek word for "unusual" for its rarity and exotic composition.
