Almandine-Spessartine garnet in muscovite mica and feldspar matrix personally collected in 1990 from the Senpe dike. Specimen size is 5.6 x 3.5 x 4.5 cm; the largest garnet crystal is 6mm. Larger individual garnet crystals were observed (to 2.5 cm) higher in the dike but could not be recovered due to safety reasons.
