頌揚(yáng)本人

Petrology and Geochemistry of Oldoinyo Lengai Lavas Extruded in November 1988: Magma Source, Ascentpatterns indicate that the carbonatite is highly fractionated. Compositional variations arise mainly between phenocryst-rich and aphyric varieties, with the aphyric variety being richer in K, Ba, Cl, F and Rb. More subtle variations in Fe, Mn, Pb and Zn may reflect groundmass sulphide sedimentation.

Olivine melilitites occur at Oldoinyo Lengai and at young tuff cones nearby; these have alkali contents that are abnormally high, even for these rocks. Olivine melilitites cannot fractionate to form phonolites; relatively low-alk
