Semi-Automatization of Support Vector Machines to Map Lithium (Li) Bearing Pegmatites
(MDPI, 2020-07-19)Machine learning (ML) algorithms have shown great performance in geological remote sensing applications. The study area of this work was the Fregeneda–Almendra region (Spain–Portugal) where the support vector machine (SVM) ... -
The metasomatic enrichment of Li in psammopelitic units at San José-Valdeflórez, Central Iberian Zone, Spain: a new type of lithium deposit
(Nature, 2020-07-02)A new type of Li mineralisation in hard rock has been found to occur in the Valdeflorez area (Caceres, Spain), where there is 111.3 Mt of resources and a mean value of 0.61 wt% of Li2O. Lithium is mainly held by very ... -
The Tres Arroyos Granitic Aplite-Pegmatite Field (Central Iberian Zone, Spain): Petrogenetic Constraints from Evolution of Nb-Ta-Sn Oxides, Whole-Rock Geochemistry and U-Pb Geochronology
(MDPI, 2020-11-12)Abundant Li-Cs-Ta aplite-pegmatite dykes were emplaced in the western Central Iberian Zone of the Iberian Massif during the Variscan Orogeny. Their origin and petrogenetic relationships with the widespread granitoids have ... -
Timing of magmatic-hydrothermal activity in the Variscan Orogenic Belt: LA-ICP-MS U–Pb geochronology of skarn-related garnet from the Schwarzenberg District, Erzgebirge
(Springer, 2022-08)[EN] Here, we present in situ U-Pb laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) ages of andradite-grossular garnet from four magmatic-hydrothermal polymetallic skarn prospects in the Schwarzenberg ... -
U-Pb dating and geochemical dataset of fracture-filling calcite veins from the Boixols-Sant Corneli anticline (Southern Pyrenees)
(Elsevier, 2022-12)U-Pb dating and geochemical analyzes ( 818 O, 813 C, A47 , 87 Sr/ 86 Sr and elemental composition) have been applied to fracture-filling calcite veins and host carbonates from the Boixols-Sant Corneli anticline, which ...
