The Reflejos de Mar Li-pegmatite, located in northwestern Argentina, is part of the Villismán pegmatite group, Ancasti District, Pampean Pegmatite Province. Four garnet crystals from outermost were analyzed by major and minor elements (SiO2, TiO2, Al2O3, Cr2O3, MgO, CaO, MnO, FeO) using electron microprobe. belongs to rare-element class, spodumene type, LCT (Li-Cs-Ta) petrogenetic family. Based...

The metamorphic reworking of mineralized pegmatites during orogenesis remains unclear, making the genesis and tectonomagmatic significance pegmatite mineralization obscure. This study demonstrates multiple utilities titanite geochemistry in establishing Caledonian evolution world’s largest intra-plutonic Nb-Y-F Paleoproterozoic host rocks Tysfjord, Northern Norway. A combination titanite-specif...

The Jiajika rare metal deposit contains the largest area of granitic pegmatite-type deposits in China. X03 vein is an immense dominated by lithium, which was found recent years. contact metamorphic belt tourmalinization and petrochemistry widely developed its wall rocks, altered rocks formed contain Li other mineralization. In this paper, tourmaline different divided into four types: two-mica q...

Almandine-spessartine garnets, from the Oxford County pegmatites and Palermo No. 1 pegmatite, record significant compositional variations according to degree of evolution their hosting rock. Garnets most fractionated (Mt. Mica, Berry-Havey, Emmons) show highest Mn, Nb, Ta, Zr, Hf values, followed by those intermediate grade (Palermo 1) and, finally, garnets barren lowest values (Perham Stop-35)...

A net of pegmatite veins crosscut gneiss and dismembered ophiolitic ultramafic rocks are abundant in the Migif-Hafafit culmination area, South Eastern Desert, Egypt. Some these pegmatites corundum-bearing. Corundum-bearing studied eight localities around complex. The present study aims to integrate field investigation, whole rock corundum chemistry, remote sensing studies, conventional methods ...

This Special Issue of Minerals, section Mineral Deposits, on the topic “Petrology and Mineralogy Pegmatite Deposits”, was inspired by currently growing scientific economic interest in pegmatites [...]
