I-Lepidolite iyiminerali ye-lithium evame kakhulu futhi iyiminerali ebalulekile yokukhipha i-lithium.Kuyi-aluminosilicate eyisisekelo ye-potassium ne-lithium, eyingxenye yamaminerali e-mica.Ngokuvamile, i-lepidolite ikhiqizwa kuphela ku-granite pegmatite.Ingxenye eyinhloko ye-lepidolite yi-kli1 5Al1.5 [alsi3o10] (F, oh) 2, equkethe i-Li2O ka-1.23-5.90%, ngokuvamile iqukethe i-rubidium, cesium, njll. Isistimu ye-Monoclinic.Umbala unobukhwebezane nopinki, futhi ungakhanya ungabi nambala, ube ne-pearl luster.Ivamise ukuba sesikalini esihle, ikholomu emfushane, inhlanganisela yeshidi elincane noma i-crystal plate enkulu.Ubunzima buyi-2-3, amandla adonsela phansi angu-2.8-2.9, futhi i-cleavage engezansi iphelele kakhulu.Uma incibilikile, ingakhipha ugwebu futhi ikhiqize ilangabi elibomvu le-lithium elimnyama.Ayincibiliki ku-asidi, kodwa ngemva kokuncibilika, ingaphinde ithinteke ngama-asidi.
