Petrological and geochemical data are presented for a suite of ultramafic xenoliths (lherzolites wehrlites) from La Grille volcano, Grande Comore island. These have peculiar textural features characterized by reaction rims or glassy patches, where clinopyroxene grows at the expense orthopyroxene. The glasses vary very strongly silica-oversaturated to undersaturated varieties. They generally homogeneous within single xenolith, extremely alkali rich, with Na2O contents (up 14 wt %) higher than...
A mantle xenolith suite from two Late Tertiary necks on Sal Island (Cape Verde Archipelago) consists of nearly equivalent amounts anhydrous spinel-bearing lherzolites and harzburgites, in which secondary metasomatic textural domains are superimposed the original protogranular textures. Detailed petrographic studies, coupled with situ major trace element analyses constituent minerals interstitial glasses, reveal complex evolutionary history Cape lithospheric mantle, depletion garnet facies to...
Many peridotite xenoliths sampled at ocean islands appear to have strongly refractory major element and modal compositions. To better constrain the chemistry, abundance origin of these ultra-refractory rocks we compiled a large number data for from nine groups islands. The were filtered petrographically signs melt infiltration metasomatism, samples affected by processes excluded. xenolith suites most are dominated harzburgites. Exceptions Hawaii Tahiti peridotites, which more fertile contain...
Abstract We present the first complete petrological, geochemical and geochronological characterization of oldest lamprophyric rocks in Italy, which crop out around Predazzo (Dolomitic Area), with aim deciphering their relationship Triassic magmatic events across whole Southern Alps. Their Mg# between 37 70, together trace element contents, suggests that fractional crystallization was main process responsible for differentiation, small-scale mixing, as evidenced by some complex amphibole...
Knowledge of the products originating from subcontinental lithospheric mantle (SCLM) is crucial for constraining geochemical features and evolution mantle. This study investigated chemistry isotope composition (noble gases CO2) fluid inclusions (FI) selected xenoliths Wilcza Góra (Lower Silesia, southwest Poland), with aim integrating their petrography mineral chemistry. Mantle are mostly harzburgites sometimes bear amphiboles, brought to surface by intraplate alkaline basalts that erupted...
Abstract: In the British Isles majority of volcanic rocks containing upper mantle and lower crustal xenoliths occur in Scotland. Most occurrences are Carboniferous–Permian age. This paper presents new data on mineral chemistry spinel lherzolite from five principal Scottish tectonic terranes. Compositional variations among minerals emphasize broad lateral heterogeneity subcontinental lithospheric across region. The remarkable range Al 2 O 3 v. CaO exhibited by clinopyroxenes compared with...
Abstract Mantle xenoliths from the Calatrava Volcanic District (CLV), central Spain, are characterized by a wide compositional range that includes lherzolites (prevalent), as well minor amounts of wehrlite, olivine (ol)-websterite and rare dunites. They generally have bulk-rock Mg# less than 89, lower any primordial mantle estimates. Intra-suite variations in modal proportions inconsistent with those predicted melting models irrespective starting composition; mineral variation diagrams show...
