Hi Ivana,

Some diagrams that may be useful. But I don not remember the reference!

Thanks Nargess!

mmm.. now i have to find the original paper :)

You may upload the pic in the google image.

However as I remember, I have seen a paper some months before that contain and debate some diagrams for discriminating the Meta and igneous Ms.

If I find it I'll send you.
