Pegmatitic rocks are very coarse-grained basement rocks abundant in quartz, feldspar
or/and mica, in places, endowed either with mega crystals of the aforementioned rock …

Abstract The Sn-Ta-Nb Penouta granite is a highly evolved rare-metal post-kinematic
leucogranite located in north-western Spain, which was intermittently mined from Roman …

Elucidating the causal relationship between parent granite and pegmatite and tracing the
magmatic-hydrothermal evolution and rare metal mineralization are intriguing scientific …

Abstract The East-Qinling pegmatite district located in the North Qinling terrane is the largest
one in the Qinling orogen, Central China. It is famous for its rare-element (REL) reserves, but …

Due to the current energetic transition, new geological exploration technologies are needed
to discover mineral deposits containing critical materials such as lithium (Li). The vast …

This work, as a fieldtrip guide, aims to provide a glimpse into the palaeoenvironments,
palaeontology, and diagenesis of one of the most productive areas for Late Jurassic …

The Penouta Sn-Ta deposit, in the northwest of Spain, is a greisenized granitic cupola
where Ta minerals occur mainly as disseminations in a leucogranite body intruded in …

Abstract Micas from the granitic pegmatites found in the Barroso–Alvão pegmatite field and
the Cabeceiras de Basto granite present variations in their composition, textural …

The geology of pegmatite systems encompasses lithology, shape, and structure while the
chemistry of major and trace elements is indicative of the ore composition; both are the …

In this paper we present textural and compositional data for columbite group minerals
(CGMs) and associated Nb-Ta-Sn oxides from lithium-beryllium-tantalum pegmatite deposits …
