Petrophysical attributes of the Seixo Amarelo-Gonçalo Li-bearing aplite-pegmatites (Guarda-Belmonte area, central Portugal)

Lithium-bearing pegmatites of the Seixo Amarelo-Gonçalo area are hosted within twomica granites of the Guarda-Belmonte area in central Portugal. The pegmatites, often concealed beneath cover material, occur at sizes difficult to detect via airborne geophysical methods but may be...

Exploring the invisible: Multi-scale geophysical studies to delineate granite-hosted Li-bearing pegmatites of the Seixo Amarelo-Gonçalo region, Portugal

A holistic geophysical approach was conducted to assess the effectiveness of electromagnetic, direct current resistivity, induced polarization, magnetic and Ground Penetrating Radar (GPR) methods for exploration of pegmatite sills in the Seixo Amarelo-Gonçalo region of central ea...
