This is how-to guide to identify

Nickel-Strunz mineral class, division, family and group. Each mineral group member and each mineral end member of a solid solution
series is more difficult to identify (same Nickel-Strunz code), it'd need probably analysis in a laboratory.

Introduction

In humans, there are three types of cones, we see white when all three cones give a 100% signal (color vision).
Color wheel: white light; cyan, magenta, yellow (the printer CMYK is darker); red, green and blue.


The identification of a mineral, needs a pure single mineral sample. Rocks are a mix of minerals. These lists use the IMA/CNMNC valid names only. In

crystallographic point groups (in seven crystal systems). The cleavage
, in mineralogy, tends to be along definite crystallographic structural planes.

  • Abbreviations/schemes:
    • "*" - discredited (IMA/CNMNC status).
    • "?" - questionable/doubtful (IMA/CNMNC status).
    • G - mineral group name.
    • I - chemical analysis incomplete. Published without approval and discredited or not approved, yet.
    • "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)

      • NN: Nickel-Strunz mineral class number
      • X: Nickel-Strunz mineral division/subclass letter
      • Y: Nickel-Strunz mineral family letter
      • ##x: Nickel-Strunz mineral/group number, x add-on letter
    • Color (color solid): 0/ white (wht), translucent (tlc); 01/ grey, metallic (gry); 02/ yellow (yll); 03/ yellowish green (y-g); 04/ green (grn); 05/ bluish green (b-g); 06/ cyan (cyan); 07/ cyan-blue (c-b); 08/ blue (blue); 09/ violet (vlt); 10/ magenta (mgt); 11/ magenta-red (m-r); 12/ red (red); 13/ orange (org); 14/ brown, black grey (brw); 15/ black (blk); etc.
    • Crystal notation: 0/ amorphous; 1/ triclinic (Tri, point group 1 or 1); 2/ monoclinic (Mono, point group 2, m or 2/m); 22/ orthorhombic (Ortho, point group 222, mm2 or mmm); 4/ tetragonal (Tetra, point group 4...); 63/ hexagonal/trigonal (Trig, point group 3...); 66/ hexagonal/hexagonal (Hex, point group 6...); 3/ cubic or isometric (Iso, point group 23, m3, 432, 43m or m3m).

Mohs scale

Mohs scale of mineral hardness
.

Note: weathered minerals might be softer, depending on the crystal orientation there might be a different hardness (kyanite, 4 or 7; muscovite, 2½ or 4) and the hardness is determined on a plane crystal face or on its edge, no fracture is involved. For instance, care must be taken with the pressure applied, quartz on the sample, and if the sample hasn't a scratch, the streak might come from the standard.

Identification of minerals

It should be a pure unweathered mineral, it shouldn't be a mix of minerals. The identification is based on a sequence of questions:

  • Is the sample very hard?
    • A.- Very hard minerals (Mohs 7 to 10)
  • Is it metallic, is its lustre metallic on a polished surface?
    • B.- Metallic lustre: native metals, metalloids, nonmetals and alloys
    • Nickel-Strunz Class 01:
      Native element minerals
    • Help table: metallic lustre but not a Nickel-Strunz Class 01 mineral
  • Is the sample's streak colored?
  • Is the sample's streak white?
    • Mohs less than 4½?
      • Da.- Identification of minerals (white streak, Mohs lower than 4½)
    • Mohs higher than 4?
      • Db.- Identification of minerals (white streak, Mohs higher than 4)

Identification of minerals

A.- Very hard minerals (Mohs 7 to 10)

Notes

  • These are just summaries, to make the sortable tables manageable.
  • Mindat.org and Webmineral.com have not always the same data. Mindat's data Nickel-Strunz 10 ed, pending publication was used for consistency.
  • Colors: Nickel-Strunz 02.AA mineral family does not have streak color sometimes. Metallic, grey, silver-white, are a color series. Dark red, dark orange, brown and black are a color series too. The color hue and streak just list small summaries.
  • Good specific gravity determinations are needed. The difference between calcite (2.7102 g/cm3), magnesite (2.98 - 3.02 g/cm3) and dolomite (2.84 - 2.86 g/cm3) is small, for instance.
  • Mineraloids like quartz varieties, volcanic glass, lapis lazuli, limonite are excluded.
  • A mineral name can be valid (pre-IMA), approved, questionable/doubtful, non valid and discredited. IMA/CNMNC valid names, found in at least 10 localities on Mindat.org and with at least 3 images on Commons, or found in at least 100 localities on Mindat.org and with at least one image on Commons were listed. Mercury (liquid), allophane (amorphous), opal (mineraloid) are IMA/CNMNC valid names. Minerals on the Mineral Identification Key II by Alan Plante, Donald Peck & David Von Bargen are listed too.
  • Only one member of a series is listed, when possible.
  • The identification of a individual group member is difficult, the identification of a end member of a solid solution series could be even more difficult. Care must be taken with, for instance: Garnet group, Tourmaline group, Pyroxene group, Amphibole group and Betafite-Microlite-Pyrochlore group and subgroups (Pyrochlore supergroup Nickel-Strunz 04.DH15 and 04.DH.20 got a major IMA/CNMNC revision 2010).
  • Cleavage, location, magnetism, optical properties, solubility, fusibility, fluorescence, radioctivity can help the identification. See further reading for other mineral search functions, use more than one key, more than once (sodalite, sulfur might have a colored streak on some databases). Mineral properties are over a range, and each individual mineral is unique. Solubility in water, reactivity with citric acid or sulfamic acid might give another hint. Splinter of borax, cryolite, cerussite will fuse on a candle flame. Magnetite is magnetic, and pyrrhotite, ilmenite and franklinite exhibit a weak magnetism. Apophyllite might have a mirror-like transparent lustre.
  • As English has not the German
    umlaut
    , it was choosen to write the names with an added "e" instead (a valid German possibility).
