Mantle xenoliths from Fuerteventura (spinel-bearing harzburgites, dunites, and rare lherzolites and wehrlites) in the easternmost part of the Canary Islands chain, are highly deformed and show a wide range in textures from protogranular and porphyroclastic with olivine and orthopyroxene porphyroclasts, to rocks with “fibrous textures” (no orthopyroxene porphyroclasts, large, porous clusters of fibrous...
The earliest (B 1 ) lavas in Vestfold and Jeloya, in the central part of the Permo-Carboniferous Oslo rift have been divided into four main groups: high Ti (HT) basalts (TiO 2 >4.2 wt.%), low Ti (LT) basaltic rocks (TiO 2 <3.7 wt.%), phonotephrites and ignimbrites. They are all highly enriched in strongly incompatible elements and have high La/Yb ratios. Initial N...
We present data on petrography, mineral and whole rock major element relations and fluid inclusions on ultra-mafic xenoliths from Quaternary to Recent alkaline basalts in Lanzarote, eastern Canary Islands. The xenoliths have been divided into two main suites: the spinel harzburgite suite (harzburgites and rare lherzolites) and the spinel dunite suite (spinel dunites and rare spinel-plagioclase dunites)...
