Abstract Beryl from Xuebaoding, Sichuan Province, western China is known for its unusual tabular habit and W–Sn–Be paragenesis in a greisen-type deposit. The crystals are typically colourless transparent to pale blue, often with screw dislocations of hexagonal symmetry on the (0001) crystal faces. Combining electron microprobe analyses laser ablation inductively coupled plasma mass spectrometry...

reservas, similares procesos metalogenéticos habrian actuado en el Paleozoico Inferior del Brea. La deformación y el metamorfisme regional hercinicos no han actuado en este sector como un importante reconcentrador de menas, y la mayor parte de indicios epigenéticos Many mineralizations, showings and geochemical anomalies de edad tardihercinicaestán relacionados alas células hidrotermales have b...

The technique known as Equal Channel Angular Pressing (ECAP) has gained prominence a transformational method for improving the mechanical characteristics of metals and alloys by subjecting them to intense plastic deformation. This study explores significant difficulties that arise when using on Aluminium 2024-Beryl Metal Matrix Composites (2024-BMMCs), providing detailed analysis complex intera...

The mineralogical studies of rare-element (REL) pegmatites are important for unraveling the ore-forming process and evaluating REL mineralization potential. Chinese Altai orogenic belt hosting more than 100,000 pegmatite dykes is famous rare-metal resources worldwide diverse types. In this paper, we present results EMPA LA-ICP-MS muscovite from typical Altai. studied Li-Be-Nb-Ta, Li-Nb-Ta, Nb-T...
