Anyone Have A different Opinion?

[Fullpan]

All the pics are of Clinosoite, a form of Epidote. At least that's what i'm told locally - anybody have another opinion? First two pics
are of a quartz shard the size of thumbnail. The rest are one quartz crystal about size of pinky finger.

They were found just 10 miles outside of Reno near a small mine dump.

Well, I'd say it sure looks like epidote. Especially #4 has me thinking that.

 

[mamabear]

what is the difference between epidote & peridote

 

[Fullpan]

HaHa - mamabear! I don't have a clue! They are both green and both beautiful - that's all I know. Was hoping someone would say green tourmaline (more
valuable, I think)

 

[Eu_citzen]

Mama,
Epidote is a member of the clinozoisite group. Peridote is gem-quality olivine.

 

[mamabear]

Ok. Are the specimens above in the beryl family? If so would it be tourmaline?

I have hand-carried specimens to the Colorado School of Mines and they have been most gracious in identifying them for me. I just went to their spectacular, free museum and showed my finds to the student attendant. Within minutes I had a whole team of students and a professor identifying and explaining the origin and formation factors of my samples. I don't know to whom you would address an E-mail but I suspect that they would shed light on your specimen's identification.

I would have to say that it is Clinozoisite (sorosilicate) which is fairly close in make-up to Kyanite (silicate) but a different color!

It's epidote. Great specimen

I failed to mention I collected about 20 specimen's all more or less the same size. Question - they are very delicate/fragile green crystals, some of which fell
off while transporting - you can see mud/debris interspersed with the crystals. How do I clean them?

P.S. - thank you folks for the correct spelling "clinozoisite".

 

[Eu_citzen]

Luke warm water and an ultrasonic cleaner is what I use for quartz.
A soft brush might be in order for more fragile specimens.

Green and dark green tourmaline crystals and tourmaline needles on smoky quartz.
