PostPosted: Aug 04, 2019 09:40    Post subject: Help needed to find all the species  

Hello everybody,

I have this specimen in my collection and I'll be pleased to find all the species that composed this piece. In my point of view, I can see Calcite, Quartz, Dolomite, maybe Chalcopyrite, Pyrite or Sphalerite.

What do you think ?

Thanks in advance for your answers.

I can see well the Calcite, Dolomite, Pyrite, Sphalerite, Quartz and hardly the Chalcopyrite but although I'm not totally sure about, I would say yes to the Chalcopyrite too...

And don't forget any unseen microminerals that might be present.
And don't forget any area of a crust mineral or two that might be present.
And don't forget, on the matrix side, of any ephemeral evaporite mineral (like epsomite) that only is visibly present when the specimen is very dry.

My point is that many mineral specimens, whether composed of 1 mineral or several, has some potential for additional minerals to be present such as crusts, micros, etc that are under appreciated and go unreported. BOB

I think the keen eye of our Master has seen the (whole?) truth :-)
