Mineral Properties Flashcards
(40 cards)
mineral properties are due to 2 things
chemical composition, crystallography
2 properties according to appearance
habit, aggregation
4 properties according to reaction to light
luster, color, diaphaneity, effects
5 properties according to stress
streak, cleavage, fracture, hardness, tenacity
4 properties according to chemical reaction
specific gravity, magnetism, radioactivity, HCl solubility
mineral completely bounded by crystal faces
euhedral
mineral partially bounded by crystal faces
subhedral
mineral that lacks crystal faces
anhedral
regular geometric shape of a crystal
habit
the way multiple mineral grains grow together
aggregation
the way a mineral reflects light
luster
luster of broken glass
vitreous
luster of a piece of resin
resinous
luster of a pearl
pearly
appears to be covered in a film of oil
greasy
luster of silk
silky
luster of a diamond
adamantine
how a mineral absorbs light
color
how a mineral transmits light
diaphaneity
mineral in powdered form
streak
planes parallel to atomic arrangement
cleavage
exhibits under no planes of weakness
fracture
response to stress without rupture
hardness
response to stress with rupture
tenacity
