1. Not a Mineral To Determine Whether Something is a Mineral,
We Ask 4 Questions:
_______________________________? NO
__________________________________? NO
Not a Mineral
____________________________________? NO
_______________________________
_______________________________? NO
If the answer to ALL 4 QUESTIONS is YES…
It’s a _________________________!

2. How Many Minerals ARE THERE?
Over ____________ minerals occur naturally on earth
LESS THAN _______ MINERALS ARE COMMON
“Common” minerals are called “_________ _________________Minerals” because they form the rocks that make up Earth’s crust
Common Rock Forming Minerals: ____________, Calcite, ____________, Halite, Gypsum

3. How Do Minerals Form? Two Most Common Ways: Minerals can also form:
From cooling____________ or ____________
From the _______________________ of mineral-rich water
Minerals can also form:
during ____________________________
When hot, mineral-rich solutions ______________ ______________ (metallic minerals forming in veins)

4. How are Minerals Classified?
Into 2 Groups based on their _____________ ___________________:
Silicates (contain Silicon (Si) ___________ Oxygen (O)
Non-Silicates (contain Si ____ O, but not ______)
By looking at the ___________ _____________ of a mineral, you can tell if it’s a Silicate or Non-Silicate Mineral

5. Silicate Minerals Quartz: (contains ONLY Si _______ O)
Contain Silicon (Si) ________ Oxygen (O)
Quartz:
(contains ONLY Si _______ O)
Feldspars (contains Si, O, + ______________
______________)
Make up _____% of the Earth’s Crust
Feldspars and Quartz alone make up over ______ % of the Earth’s Crust!

6. Halite (NaCl) Calcite (CaCO3) Silver (Ag), Copper (Cu) Galena (PbS)
Non-Silicate Minerals
Do NOT contain Silicon (Si) _______ Oxygen (O)
They CAN contain either Si ________ O
Make up only _____% of Earth’s Crust
Halite (NaCl)
Calcite (CaCO3)
Silver (Ag),
Copper (Cu)
Galena (PbS)
Pyrite (FeS2)
Organized into 6 groups (You don’t have to memorize all the names!) Pg. 113

7. Are the Following Minerals Silicate, or Non-Silicate Minerals?
Fluorite (CaF2) ______________
Hematite (Fe2O3) _______________
Orthoclase (KAlSi3O8) ____________
Pyrite (FeS2) ________________
Quartz (SiO2) _________________

8. Crystal Structure All minerals have a crystalline ___________
Crystal shape is determined by the arrangement of ____________ in the solid
Really nice big crystals only form where ________ allows (caves, bottom of bodies of water, etc)
Usually crystals don’t have room to grow and so they grow as a big _________. This makes it difficult to determine crystal shape.
