What Makes a Mineral?

Atoms make elements, which make Minerals!

minerals
Minerals
  • The purist form of matter which is the building foundation of earth’s materials.

Fluorite (CaF2)

scientific definition of a mineral
Scientific Definition of a Mineral
  • To be a mineral it must:
    • Form naturally
    • Be inorganically formed
    • Be in the solid phase
    • Have a definite chemical composition
    • Have an ordered atomic arrangement
formed naturally
Formed Naturally?
  • Rocks and soil are made from minerals.
  • It is only a mineral if it was made by nature’s physical processes.
  • Some scientists have created “minerals” in a laboratory…

Are these considered a mineral according to the definition of a mineral?

NOPE!

formed by nature mineral
Formed by nature- Mineral

Dioptase(CuSiO2(OH)2)

my favorite!

inorganically formed
inorganically formed?
  • Cannot be made from living things or the remains of living things.
  • Coal, a mineral or not?
  • Not a

Mineral→

solid
Solid?
  • It is only a mineral if it is in the solid phase of matter:
definite chemical composition
Definite chemical composition?
  • A Mineral’s chemistry is the elements that make up the minerals matter.
  • Minerals are either single elements or compounds.
single element mineral
Single element mineral

Chemical name

  • Gold (Au) Silver (Ag)
  • Sulfur (S)
compound minerals
Compound Minerals

Chemical Name

  • Quartz (SiO2) Potassium

Feldspar(KAlSi3O8)

ordered atomic arrangement
Ordered Atomic Arrangement?
  • All minerals have crystals that form in patterns starting with the smallest atom.
  • The arrangement of these atoms makes geometric shapes
