Carbonatites are familiar to students of petrology as rare igneous rocks formed
predominantly of carbonate, whose only modern expression is a single active volcano that …

Recent increase of the demand for rare earth elements (REEs), especially dysprosium and
terbium used in the permanent magnet industry is modifying a concept of the REE …

A total of 4344 magmatic U-Pb ages in the range 2300 to 800 Ma have been compiled from
the Great Proterozoic Accretionary Orogen along the margin of the Columbia/Nuna …

We present new experiments, combined with a re-evaluation of published data, to
characterize the topology of the silicate–carbonate two-liquid solvus in the five-component …

Carbonatites are rare but worldwide occurring igneous rocks and their genesis remains
enigmatic. Field studies show a close spatial but controversially debated genetic …

Major and trace element compositions, and Sr–Nd–Pb and O–C isotope data for Cenozoic
carbonatites (WSC) in western Sichuan, east Tibet, China are presented in this paper. The …

Geochemically, the large family of alkaline plutonic rocks (both Qtz-undersaturated and-
oversaturated compositions) can be subdivided into metaluminous [(Na2O+ K2O)< Al2O3] …

The Himalayan Mianning–Dechang REE belt, western Sichuan, SW China, is approximately
270 km long and 15 km wide, and contains total reserves of> 3 Mt of LREE, including one …

Most studies of compositional heterogeneities in the mantle, related to recycling of crustal
sediments or delaminated subcontinental lithosphere, come from oceanic setting basalts. In …

Liquid immiscibility has become the preferred mode of genesis for the carbonatite rocks,
which commonly, but not exclusively, accompany silicate rocks in alkaline-rock complexes …
