#1
Front (Question)

Diagnostic vs. Ambiguous Properties

Back (Answer)

D - useful in identifying an unknown mineral (Eg. halite has a salty taste) A - properties that vary among different specimens of the same mineral (color is the least helpful)

#2
Front (Question)

Optical Properties

Back (Answer)

Luster, Color, Streak

#3
Front (Question)

Crystal Shape, or habit

Back (Answer)

common/characteristic shape of individual crystals or aggregates of crystals. Some grow in three directions equally, whreas others tend to be elongated in one direction or flattened if growth in one dimension is suppressed. Terms: equant, bladed, fibrous, tabular, cubic, prismatic, platy, blocky, and banded

#4
Front (Question)

equant

Back (Answer)

Garnet, Olivine

#5

Bladed

Back (Answer)

Kyanite, ACtinolite

#6
Front (Question)

Fibrous

Back (Answer)

Tremolite, serpentine, silimanite

#7
Front (Question)

Tabular

Back (Answer)

Mica (biotite and muscovite), talc, gypsum

#8
Front (Question)

Cubic

Back (Answer)

Halite, pyrite, galena

#9
Front (Question)

Prismatic/Columnar

Back (Answer)

quartz, beryl, tourmaline

#10
Front (Question)

Blocky

Back (Answer)

halite, pyrite,flourite

#11
Front (Question)

Banded

Back (Answer)

Agate, Tiger’s eye, Banded Jasper

#12
Front (Question)

Moh’s Scale of Hardness (1-10)

Back (Answer)

Talc, Gypsum, Calcite, Flourite, Apatite, Orthoclase, Quartz, Topaz, Corundum, Diamond

#13
Front (Question)

Cleavage

Back (Answer)

break along planes of weak bonding

#14
Front (Question)

Fracture

Back (Answer)

chemical bonds that are equally strong in all directions (minerals produce uneven surfaces known)

#15
Front (Question)

Irregular Fracture

Back (Answer)

rough jagged surface

#16
Front (Question)

Conchoidal Fracture

Back (Answer)

smooth, cruved surfaces such as quartz + olivine

#17
Front (Question)

Tenacity

Back (Answer)

how a mineral responds to stress (brittle, malleable, etc.)

#18
Front (Question)

Specific Gravity

Back (Answer)

Most minerals have between 2-3

#19
Front (Question)

Specific Gravity of Quartz

Back (Answer)

2.63

#20
Front (Question)

Specific Gravity of metallic minerals

Back (Answer)

pyrite, copper, and magnetite are twice as dense as quartz and have twice the specific gravity of quartz

#21
Front (Question)

Galena Specific Gravity

Back (Answer)

7.5

#22
