Rare-element pegmatites have diverse chemical signatures and are important sources of strategic metals such as Li, Cs Ta.The two main hypotheses to explain rare-element pegmatite formation 1) residual magmas from granitic rocks' crystallization, 2) partial melts a relatively rareelement-rich source.In southeast Ireland, spodumene spodumene-free dykes occur along the eastern margin S-type Leinster Granite batholith.With indistinguishable emplacement ages around 400 Ma, origin Li-rich...
Open access to harmonised digital data describing Earth's surface and subsurface holds immense value for society. This paper highlights the significance of open geoscience ranging from shallow topsoil or seabed depths 5 km. Such play a pivotal role in facilitating endeavours such as renewable geoenergy solutions, resilient urban planning, supply critical raw materials, assessment protection water resources, mitigation floods droughts, identification suitable locations carbon capture storage,...
Abstract Compared to average crustal abundances, high field strength elements (HFSEs) including Zr, Nb, Hf, Ta, and U are commonly enriched in rare element pegmatites. Albite-spodumene pegmatites may show economic grades of these elements, along with Sn, primarily oxide minerals. Processes leading enrichment precipitation HFSEs rocks not well understood. Here, we characterize the textures geochemistry minerals HFSEs, tin, base metals Leinster albite-spodumene We use data infer processes for...
Pegmatitic deposits of critical metals (e.g., Li, Ta, Be) are becoming increasingly significant, with growing interest in understanding metal enrichment processes and potential vectors to aid the discovery new resources. In southeast Ireland, Leinster pegmatite belt comprises several largely concealed Li-Cs-Ta albite-spodumene-type pegmatites. We carried out detailed mineralogical characterization whole-rock geochemical analyses six drill cores intersecting bodies their country rocks....
Geological units are the fundamental building blocks that help understand regional geological history and architecture. Classifying these correctly is therefore crucial, as acknowledging how they relate to each other. This where traditional definitions fall short, which increasingly becoming evident with ongoing effort of setting up advanced knowledge systems rely on semantic grounding. In exploring way forward for improvements, we use foreland basin related concepts introduce a geotemporal...

ABSTRACT In phosphorites, the content and distribution of rare earth elements are linked to environment phosphogenesis. This paper focuses on question sources processes controlling element apatite from Belgian phosphorites formed during three major phosphogenic events in Lower Palaeozoic, Late Cretaceous Cenozoic. To constrain processes, new data include petrological, mineralogical (including cathodoluminescence Raman spectroscopy) situ trace Sr O isotope analyses apatite. Fluorapatite...
