Attached paper on rhyolites may be of help to you!!

Munazzam Ali Mahar

Gavril, thanks for the papers, carbonatites and pyroxenite are reported in New Mexico volcanics closer to Rio-Grade rift, and also in Kilburn hole. I was wondering the nature of magma sources producing HREE Sierra Blanca and topaz rhyolites.

Mahaveer, thanks for sharing the paper.
