I'd like a paper that talk about this decarbonation reaction in the condictions described before. I found only a paper that talks about that, but i cannot find it becaus it's a presentation of 2003. The paper is:
Shirasaka, M. and Takahashi, E. (2003) A genesis of carbonatitic melt within subducting oceanic crusts: high-pressure experiments in the system MORB-CaCO3, the 8th International Kimberlite Conference, Victoria, Canada
A Keshav's paper talked about that, i know the pubblication for this. I wanted to know if some other one said something like that. The paper said, according to keshav, that it's been found a co2 vapor phase and melt between 8-15 Gpa.
Keshav paper: Experimentally dictated stability of carbonated oceanic crust
to moderately great depths in the Earth: Results from the solidus
determination in the system CaO‐MgO‐Al2O3‐SiO2‐CO2
This is a list of papers which have cited S&T (2003) obtained with Google Scholar

(Please let me know if that does not work for you.)
It contains links to PDF files for some of those papers two of which are on ResearchGate:

I finally got the paper and they says that in their experiment (MORC CaCO3) between 13-15 Gpa they found solidus, melt anc CO2 Vapor. This means that occurred a decarbonization reaction at 13-15 Gpa and that co2 vapor is petrologically stable?
I saw every paper and, except one, noone talk about a co2 vapor phase between 13.15 Gpa, they talk about other things like the systems that they got.
