Gabal El-Ineigi fluorite-bearing rare-metal granite with A-type affinity, located in the Central Eastern Desert of Egypt, is distinguished by its abundance large fluorite-quartz veins and mafic enclaves. Plagioclase (labradorite to oligoclase), Mg-rich biotite, hornblende are main components enclaves, significant amounts fluorite as essential phases, titanite Fe-Ti oxides (Nb-free rutile ilmeni...

Introduction: The lower crust of the Moon remains a critical unknown for models of lunar compositional mass balance and for models of petrogenesis of lunar rock types. Key questions addressed here are (1) how mafic are the rocks of the lower crust and (2) are they ferroan or magnesian? Answers to these questions bear on the concentration and distribution of radiogenic heat-producing elements an...

Abstract The crust of southern Tibet shows strong azimuthal and radial seismic anisotropies. However, their origin has remained ambiguous. Here we characterized the composition, microstructure, properties amphibole-rich deep-crust xenoliths exhumed rocks from a terrane in Tibet. show typical magmatic textures have amphiboles with homogenous chemical low intracrystalline deformation, but crystal...

Introduction: Domes and more oblong and irregularly shaped mounds have been described from the Arcadia and Utopia Planitiae regions on Mars [1,2,3]. In [1] it was suggested that the domes in Arcadia were volcanic domes and they were compared to terrestrial volcanic domes with silica contents generally higher than have been associated with known volcanic products on Mars. In [2] it was posited t...
