Does any one knows what is this mineral. It comes from Afghanistan or Pakistan.

another specimen

How many sides does the crystal have?

At a glance and without knowing the structure/hardness, it reminds me of Diopside.

It has four sides, look at this last pic. but to me it doesn't look at all like diopside.

thanks

Spodumene????

Diopside or forsterite?

6th Jun 2005 22:32 UTCAymeric Longi

from pics I have seen in the gallery it is not spodumene, neither forsterite.

The guy who sold it to me in Peshawar didn't know what it is, he told me it's something new.

Does anyone manage to open the third picture ? I can't maybe it's too large file... what is the maximum file allowed to upload ?

Thanks

Looks to me like it could very possibly be hiddenite ( a green variety of spodumene) especially since it is coupled with pink, another color that spodumene commonly exhibits.

I maybe wrong, but some years ago there was an article in LAPIS about gemmy tremolite crystals from somewhere, which look - apart from the colour - very much like these crystals.

Anyway, to be sure, you have probably to do a RDX analysis

What about Sphene (Titanite)? The crystal in the far left corner struck me to be similar.

Best wishes,

thanks for suggestions, but from the pics I have seen here at mindat, it's none of them.

I'll try to find some time to go to the mineral museum and ask.

I'll post the result !

thanks !

If you hadn't said it has four sides, I would suspect fluorapatite - it looks like it.

What is the mineral's hardness?

The blocky appearance suggests a tetragonal mineral like meionite or vesuvianite.

8th Jun 2005 05:47 UTCPeter C

After looking at the 3rd photo - it does not look tetragonal. I'm leaning more towards what Thomas is suggesting - gemmy tremolite or perhaps another amphibole like pargasite.

looks like a scapolite to me
