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 and related rocks exhibit a significant variation in their content of high-field-
strength elements (HFSE), ie Ti, Nb, Ta, Zr and Hf. The average abundances of these …

Fuerteventura—the second largest of the Canary Islands consists of Mesozoic sediments,
submarine volcanic rocks, dike swarms and plutons of the Basal Complex, and younger …

The phase relationships of three peralkaline rhyolites from the Kenya Rift have been
established at 150 and 50 MPa, at oxygen fugacities of NNO− 1· 6 and NNO+ 3· 6 (log fO 2 …

The generation of magmas in the East African Rift System (EARS) is largely the result of
either:(A) melting of easily fusible compositions located within the lithospheric mantle due to …

A carbonatite-derived fluid trapped under closed-system conditions is preserved as fluid
inclusions in quartzitic country rocks of the Kalkfeld carbonatite complex, Namibia. The fluid …

For 40 years, the case for the existence of carbonate magmas rested on field observations of
carbonatite intrusions, in which the lack of thermal effects raised an apparent conflict with the …

Experimental results from the systems CaO–MgO–SiO2–CO2, Na2O–CaO–Al2O3–SiO2–
CO2, and a primitive magnesian nephelinite mixed with carbonates have been combined for …

In order to define the conditions for the formation of immiscible carbonatite magmas in the
lithosphere and in the crust, we have conducted phase equilibrium experiments to …

Experimental results for a carbonated, high-CaO evolved nephelinite at 0.2 and 0.5 GPa at
900–1040° C are presented. Immiscible carbonate and silicate liquids are in equilibrium …
