LIBS analysis is efficient in the classification of mineral grains and prospecting Be Li granitoid rocks.

the shah-kuh granitoid has intruded in the triassic–jurassic, pelitic and psammitic low-grade metamorphic rocks of the ne lutblock, in central iran. cordierite porphyroblasts are common in the southern pelitic sediments, but are rare in the northern psammiticrocks, in the contact aureole. deformation fabrics in the contact aureole are well-preserved within the cordierite porphyroblasts. therela...

The Harachiyama Formation comprises Lower Cretaceous volcanic rocks, which are distributed in the eastern margin of Kitakami Mountains northeastern Japan. Whole-rock chemical analysis, U–Pb zircon dating and Hf isotope analysis were performed to constrain formation age magmatic origin was discussed. lava tuff samples from Omoto Tsukue areas supported island-arc rhyolitic rocks (SiO2 content > 7...

The emplacement of the Mesoproterozoic Götemar Pluton into Paleoproterozoic granitoid host rocks of the Transscandinavian Igneous Belt is re-examined by microfabric analysis, including cathodoluminescence microscopy. Field data on the pluton-host rock system are used to strengthen the model. The Götemar Pluton, situated on the Baltic Shield of SE Sweden, is a horizontally zoned tabular structur...

Abstract The present paper discusses the geochemical affinities, origin and ages of Jurassic granitoids Sanandaj-Sirjan Zone (SaSZ) in eastern part Zagros Thrust Zone. A multidisciplinary, integrated approach was carried out using existing granitoid data (major, trace, rare earth element isotopes) knowledge regional geology (geodynamic metamorphic setting), coupled with geophysical (magnetic su...
