Dear Masoud,

Thank you very much for the references, they all have very interesting things.

Cheers,

Alejandro 

Dear Alejandro, This paper and references cited in can be also a good complement to the papers provided by Masoud. Wu and co-authors document constraints on the conditions of zircon baddeleyite transformation. Regards, Anicet
