okay so ive looked everywhere for this stuff and i cant find it.
here are the questions.

1. flourite
2. sphalerite
3. how does the amount of space affect the apperance of a crystal?
4. identify the crystal shapes of these minerals:
a.feldspar
b.corundum
c.calcite
d.galena
any of those answers are great!
thankyouu!
1. fluorite is the most colorful mineral and Fluorite has perfect octahedral cleavage, It has a hardness of 4, and it is transparent to translucent and has a vitreous luster.
2. sphalerite- important ore of zinc, hardness 3.5-4, Cleavage: perfect in six directions
Color: black to brown also yellow to red and very rarely colorless
Transparency: crystals are transparent to translucent,
Associated Minerals: Arsenopyrite, Barite, Chalcopyrite, Calcite, Dolomite, Fluorite, Galena, Magnetite, Pyrrhotite, Pyrite, Quartz, Siderite, and many other mineral verities
3. The amount of space available for a crystal to fill affects its final shape and size
4 mineral shapes
a. feldspar- Monoclinic (Flat tabular or prism-shaped crystals)
b. corundum- typical tapered shape and hexagonal cross section
c. calcite- many different shapes (Dog Tooth is one famous one)
d. galena- forms many crystal shapes
Where did you look “everywhere?” all of the is accessible in any mineral site on the web. You may have… You need more confidence in yourself. You probably know these answers already.
