Field and hand sample photographs of Li-mineralized pegmatites from the Fregeneda-Almendra pegmatite field. (a) Ten to 20 m thick petalite-rich pegmatite crosscutting the foliation (S) of micaschists from the Schist-graywacke Complex (SGC) at the Bajoca mine. (b) Petalite-rich pegmatite at the Hinojosa locality. (c) K-feldspar phenocrysts within a fine-grained assemblage of quartz-albite-amblygonite-group minerals (AGM) and cassiterite in petalite-rich pegmatite from the Bajoca mine. (d) Two-meter-thick Li-mica-rich pegmatite dyke intruding metasedimentary rocks from the SGS at the Ramalha-Est locality. (e) Layered Li-mica-rich AGM-bearing pegmatite (sample P010). The growth direction reflected by albite phenocrysts is indicated. (f) Li-mica-rich pegmatite from the Feli mine. Mineral abbreviation from Whitney and Evans (2010).
