Ramfoss-pegmatitten, Kløftefoss, Modum, Buskerud, Norge
A tourmaline-rich plagioclase-quartz pegmatite containing sharp crystals of tourmaline (schorl) and partly excavated for specimens in the 19th and 20th centuries. It belongs to the Kongsberg-Modum pegmatite district in the Kongsberg lithotectonic unit. The pegmatite forms a relatively small, 15 m long and 6 m wide, isolated body
