26
Planes of weak bonds within the crystal lattice
Cleavage
27
6 cleavage, 12 faces
Dodecahedral
28
4 Cleavage and 8 faces

Rhombohedral
31
2 clevage and 4 faces
Prismatic
32
1 cleavage and 2 faces
Basal
33
The appearance of the mineral when it does not break along the cleavage plane
Fracture
34
Type of fracture that the surface has a rounded protuberance accompanied by circular grooves
Conchoidal
35
Type of fracture that the surface has no protuberance
Even
36
Type of fracture that the surface has a certain larger parts resembling to fibers
Fibrous
37
Type of fracture that the surface is jagged and with sharp edges
Hackly

44
Example of coupled ionic substitution
Plagioclase feldspar (Na,Ca)(Si,Al) Si2O8
45
Example of limited ionic substitution
Calcite and magnesite
46
Appearance of different colors when a crystal is viewed in transmitted light in different directions.
Pleochroism
47
Some minerals will emit visible light when heated below red heat.
Themoluminesence
48
Shows a series of colors due to light undergoing reflective interferences with itself either on the surface in the interior.
Iridescene
49
Pearly reflection from the interior of a mineral, like the effect of a glass of water to which a few drops of mil have been added.
Opalescene
50
Minerals with an isometric crystal system that have light pass through them and moves in all directions with equal velocity, hence, a single refractive index.
Isotropic minerals
51
Minerals that do not have an isometric crystal system with light passing through them and have varying velocities of light moving in different directions and orientations, hence, more than one refractive index.
Anisotropic minerals
52
Minerals that are strongly attracted to magnets,
Ferromagnetic
53
Minerals that tend to create its own magnetic field
Ferromagnetic
54
Minerals that have have a net magnetic moment equal to zero.
Anti ferromagnetic
55
Two direction have two distinct colors
Dichroism
