prop:
Color
Streak
Luster
Cleavage and Fracture
Density
Hardness
Other
flourescence
magnetism
acid test
a mineral to be a mineral must have five criteria
inorganic
fixed ement formula
no man made
atoms arraged in a a specific a structure
the solid must exist as a solid in it'snormal conditions on earth
minerals are the building bocks of rocks
so
with the piling up of minerals rock form, ex: kidneystone
Naturally occurring, inorganic solid with a definite chemical composition and an orderly arrangement of atoms
how break
Cleavage: Break along smooth, flat surfaces
Fracture: Break with uneven, rough or jagged surfaces
streak
The color of a mineral in powdered form
luster
The way a mineral reflects light
metallic
non metallic
glassy
Dull
Pearly
Silky
density: mass/ volume
Ratio of mineral’s weight compared with the weight of an equal amount of water
its' proriety depend on the arrangment of the atoms
4000 types
colour not always reliable
