For example, the hydrous mineral Opal has a loosely defined composition with an inconsistent amount of water in its structure, thus its chemical formula is written as "SiO 2 · nH 2 O". Some minerals, such as Torbernite, have a varying amount of water within fixed limits. The chemical formula for Torbernite is "Cu(UO 2)(PO 4) 2 · 8-12H 2 O".

2021-11-22 · mineral - mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level ...
