Classification of Minerals

2021-12-2 · Minerals can be classed as heavy and light, thereby eliminating many of the possibilities that a specimen could be due to its other physical properties. Minerals with a specific gravity of 3.5 or more are generally considered as heavy, whereas minerals with a specific gravity of 3.2 or less are considered to be light.

Montmorillonite | Al2H2O12Si4

EDXA identifies and quantifies elements above atomic number 8. Since the basic classification of clay minerals is based on structural formula and the atomic composition is similar for many different clay minerals, EDXA cannot provide secure identification except by comparison with standards previously identified by other means.

mineral

2  · 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 …
