Abstract

Poikilitic eudialyte outcrops in a strongly peralkaline phonolithic cumulo-dome in Jabal Al Hasawinah, Libya. Textural relationships reveal that the eudialyte has formed at a very late stage of the rock petrogenesis. Electron microprobe analyses confirm its volatile (hydrous) nature and low REE content.
