SPECTROMETRY ANALYSIS TECHNIQUES FOR LCT PEGMATITE HALO IDENTIFICATION: THE ROL...
Cardoso Fernandes, J; Rodrigues, C; Alexandre Lima; Ana Teodoro; Ribeiro, MD; Roda Robles, E; Errandonea Martin, J; Garate Olave, ILithium-Cesium-Tantalum ( LCT) pegmatites are enriched in several raw materials. However, their small size and the limited penetration depth of the sensors, limits remote sensing approaches. This study evaluates the usefulness of hyperspectral data to identify geochemical halos related to LCT pegmatites by exploiting the information acquired in European projects. It was possible to identify key minerals and rel...
Metasomatic effect of Li-bearing aplite-pegmatites on psammitic and pelitic met...
Errandonea-Martin, J; Garate-Olave, I; Roda-Robles, E; Cardoso-Fernandes, J; Lima, A; Ribeiro, MD; Ana TeodoroFluid-assisted mass transfer and re-equilibration of mineral phases are common consequences of metasomatism associated with igneous intrusions. The addition and/or removal of chemical components in these environments may result in the generation of metasomatic aureoles, which can be recognized by their mineralogy and geochemistry. Due to an increasing demand for critical raw materials used in green energy techn...
Optimization of the Tartrate-Resistant Acid Phosphatase Detection by Histochemi...
Galvão, MJ; Santos, AR; Ribeiro, MD; Ferreira, A; Nolasco, FAccording to the new KDIGO (Kidney Disease Improving Global Outcomes) guidelines, the term of renal osteodystrophy, should be used exclusively in reference to the invasive diagnosis of bone abnormalities. Due to the low sensitivity and specificity of biochemical serum markers of bone remodelling,the performance of bone biopsies is highly stimulated in dialysis patients and after kidney transplantation. The tart...
