What are your tricks for identifying augite/pyroxene vs. hornblende?
(it's hard to in pictures. I wasn't sure which one it was myself) Cleavage plane angles, hornblende is sparklier, augite typically has a greenish tint, hornblende is typically black, etc.
Basically what Scott said, but also hornblende is usually more lustrous? Maybe I'm using the wrong terminology but not sure.
Yea the luster is different. I used the technical term of "sparkly" to describe it.

Is someone going to place another question?

I'm gonna put down some more questions then... if you guys do not mind.

1. What is a ruby a variant of?
2. What is an emerald a variant of?
3. Differentiate each of the gypsum varieties.
4. Differentiate breccia and conglomerate.

3. Differentiate each of the gypsum varieties.
4. Differentiate breccia and conglomerate.
1. Corundum
2. Beryl
3. Selenite = clear, satin spar = sheets of satin-y gypsum similar to ulexite in appearance, alabaster = fine grained
4. Breccia = cemented sharp, jagged fragments, conglomerate = cemented, rounded fragments.

Question
Image
1. Identify this mineral.
2. How did you identify it?
3. What is its chemical composition?
4. What is its luster?[/hide]

Is hide broken or am I doing it wrong, it's the question so doesn't matter as much please tell me what I'm doing wrong.

Remove the quotes portion. Also, make sure you have a | symbol after "Question".

Dunno what's wrong with the image... and accessing the link makes it obvious...
