In this case study, 2D micro energy dispersive X-ray fluorescence (µ-EDXRF) surveys were performed in the nepheline syenite (NS) of “Serra de Monchique” located southwest region Portugal (Algarve, Iberian Peninsula). The results allow identification mineral matrix certain elements classified as critical raw materials (CRMs). Due to substitution effects, some scarce transition elements, such Zn ...

Feldspar (alkali feldspar and plagioclases) in recent years feldspathoid minerals are used as raw materials the ceramic-glass industries. The igneous rocks such granite, syenite foid which mainly contain these have potential to be materials. Some inclusions within feldspatic affect extremely negatively desired values for material. In this study, effective processes alteration of Özvatan syenite...

Abstract This study presents new whole rock major and trace element, Sr-Nd isotopic, petrographic, geochronologic data for seven latest Permian (Changhsingian)–Late Triassic (Carnian) granitoid intrusions of the northwestern northeastern Taimyr Peninsula in Russian High Arctic. U-Pb zircon ages, obtained using secondary ion mass spectrometry (SIMS), sensitive high-resolution microprobe (SHRIMP)...

In our previous study on petrogenesis of quartz syenite and granite porphyry, the host rocks Late Mesozoic Shapinggou Mo deposit in Qinling–Dabie orogenic belt, we found that initial Sr isotopic composition is strongly affected by degree K-alteration. Here, provide further evidence their minerals to investigate geochemical behaviour trace elements isotopes during alteration explain phenomenon d...
