Earth:Classification of silicate minerals

From HandWiki
Short description: List of IMA recognized minerals and groupings

This list gives an overview of the classification of minerals (silicates) and includes mostly International Mineralogical Association (IMA) recognized minerals and its groupings. This list complements the List of minerals recognized by the International Mineralogical Association series of articles and List of minerals. Rocks, ores, mineral mixtures, non-IMA approved minerals and non-named minerals are mostly excluded.

Classification of minerals

Introduction

The grouping of the New Dana Classification and of the mindat.org is similar only, and so this classification is an overview only. Consistency is missing too on the group name endings (group, subgroup, series) between New Dana Classification and mindat.org. Category, class and supergroup name endings are used as layout tools in the list as well.

Abbreviations

  • "*" – mineral not IMA-approved.
  • "Q" – doubtful/questionable.
  • Rn – renaming.
  • Rd – redefinition.
  • "REE" – rare-earth element (Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu).
  • "PGE" – platinum-group element (Ru, Rh, Pd, Os, Ir, Pt).
  • "s.p." – special procedure.
