is a naturally occurring, solid land inorganic substances, which can either be an element or compound with stable crystalline structure and definite chemicalstructure and properties.

Physical Properties of Minerals

Cluster Color streak Hardness Cleavage Fracture Magnetism Crystal Habit Specifie Gravity

refers to the quality of light on the surface of rocks, (crystals or minerals. A mineral with a high luster is very reflective.

cluster

refers to the color of a freshly broken surface of mineral. A mineral's color is caused by the absorption, or lack thereof, of visible light by their crystalline structure.

color

refers to the color of the finely formed powder produced by rubbing the mineral against a streak plate or unglazed porcelain tile.

streak

is a mineral's ability to resist scratching or abrasion. It does not refer to how easily the mineral is broken.

hardness

is the tendency of the mineral to split, or cleave, along of planes of weakness. If the minerals break apart in similar pieces, it is said to have good cleavage. If the break isuse not define, the cleavage is classified as poor

cleavage

refers to the property of minerals to break irregularly when they do not yield to cleavage or parting surfaces.

fracture

refers to the property of being attracted or repelled by a magnet.

magnetism

refers to the visible shape exhibited by the minerals

crystal habit

is a measure of relative density of a mineral. It is determined by comparing its relative mass to water.

specific gravity

Specific Gravity =

mass of mineral / mass of equal volume of water

Classes of Minerals

NATIVE ELEMENT CLASS CARBONATES CLASS HALIDE CLASS OXIDE CLASS PHOSPHATE CLASS SILICATE CLASS SULFATES CLASS SULFIDES CLASS

are minerals composed of metals, their alloys and non-metals

native element class

native element class example

Metal - chromium, gold, manganese Non-Metals - diamond, graphite Metalloids - brass, iron and nickel

minerals composed of carbonates, nitrates and borates.

carbonates class

minerals composed of anions of halogen ( CI, F, Br, I)

halides class

minerals containing oxides and hydroxides

oxides class

minerals containing phosphates, arsenates, vanadates and antimonates.

minerals composed of silicate tetrahedron (Si04)

silicate class

minerals composed of sulfates, sulfides, chromates, molydates, selenates. Tellurates tellurites, and tungsten.

sulfates class

minerals composed of sulfides selenides, tellurides, arsenides, antiminides, bismuthides and sulfosalts.

sulfides class
