Igneous and/or Metamorphic
Garnet is a dodecahedral mineral found in these types of rocks.
What are metamorphic rocks?
These physical properties are associated with minerals that bond via metallic bonding. (name two of the four)
What are malleable, high electrical conductivity, ductile, and metallic luster?
This optical property is only seen in PPL and is related to the difference between the refractive index of the mineral and the material next to the mineral
What is relief?
This mafic mineral has a solid solution with Mg and Fe, and is the first mineral formed on the discontinuous side of Bowen's Reaction Series
What is olivine?
Biotite is a black, planar mineral with one good cleavage that is found in these types of rocks.
What are igneous and metamorphic rocks?
This element has the highest electronegativity on the periodic table.
What is fluorine?
One of the major differences between clinopyroxene and orthopyroxene in XPL is this optical property.
What is extinction angle? (or What are interference colors?)
This mineral is the name of the middle part of the solid solution between Diopside and Hedenbergite.
What is augite?
Olivine is a green, magnesium-rich mineral found in these types of rocks.
What are igneous rocks?
In biotite, Ti4+ is in octahedral coordination with oxygen. This means there are this many oxygen bonded to each Ti.

What are magnesite and siderite?
Plagioclase feldspar is a white mineral that makes lathes/rectangular shapes that is found in these types of rocks.
What are igneous and metamorphic rocks?
Phyllosilicates have one good cleavage because of van der Waals bonds between these.
What are the bonds between TOT sandwiches? (not between layers within the sandwiches)
No light passes the upper polarizer when an anisotropic mineral creates a fast and slow ray that are _____________.
What is "in phase"?
This mineral can sometimes be magnetic because of a solid solution between Cr3+ and Fe3+ in the spinel mineral group.
What is chromite?
