Hello everybody,
hope some of you can help me out on two questions related to each other:
1) Is there a source which clearly defines when to call a mineral phase
unmixing from a solid solution "exsolution" or "precipitate"?
2) Do you know of any article expaining explicitly (reaction equations
etc.) how rutile unmixes from high-tempertaure garnet?
I know of three such papers for ultrahigh-pressure garnets (Van
Roermund, 2000; Zhang et all. 2003 and Yang & Liu, 2004),
but none for granulite facies rocks etc.
Please let me know if you have come across or even authored any such
references.
Sincerely,
Alexander Proyer
