Hello,
I'm writing an article about P-T conditions of the Maya block in southern
Mexico, I'm a PhD student.
For my temperature calculations I used the Grt-Bt Fe-Mg exchange
thermometer, I used biotites included in garnet, touching garnet and not in
contact with garnet.
The two referees of the article agree that I can not use biotite not in contact
with garnet for these calculations. A Couple of authors (Indares and
Martignole, Bucher and Frey) say that biotites not in contact with garnet can
provide temperatures of the peak of metamorphism.
Can anyone help me with this matter?
Thanks
I also need to know which a-x relations are incorporated into the software
Thermobarometry of Kohn and Spear, for the GRAIL baromether.
