Li in minerals from the Ilímaussaq alkaline intrusion
Li was analysed by instrumental neutron activation analysis and Cerenkov counting in 120 mineral samples (30 species) from the Ilimaussaq alkaline intrusion, South Greenland. More than 0.23 wt. % Li (0.5 wt. % Li20) is found in polylithionite, neptunite, riebeckite, Na-cookeite, ephesite, arfvedsoni...
