Ilitye lentaba-mlilo (elidla ngokubizwa ngokuba yi-pumice okanye i-porous basalt) sisixhobo esisebenzayo nesihambelana nokusingqongileyo, nelitye elinqabileyo kakhulu elibunjwe yiglasi yentaba-mlilo, iiminerali, kunye namaqamza emva kogqabhuko-dubulo lwentaba-mlilo.Ilitye le-volcanic liqulethe ezininzi iiminerali kunye nezinto ezilandelwayo ezifana nesodium, i-magnesium, i-aluminium, i-silicon, i-calcium, i-titanium, i-manganese, isinyithi, i-nickel, i-cobalt, kunye ne-molybdenum.Ayinamitha kwaye inamaza emagnethi akwi-infrared.Emva kogqabhuko-dubulo lwentaba-mlilo olungenalusini, emva kwamashumi amawaka eminyaka, abantu baya befumanisa ngakumbi ukubaluleka kwayo.Ngoku iye yandise imimandla yesicelo sayo ukuya kumabala afana nolwakhiwo, ugcino lwamanzi, ukugaya, izixhobo zokuhluza, amalahle okosa inyama, ukucwangciswa komhlaba, ukulima okungenamhlaba, kunye neemveliso zokuhombisa, idlala indima engenakuphinda ibuyiselwe kumashishini ahlukeneyo.

I-Basalt luhlobo lwelitye elisisiseko leVolcanic, eliluhlobo lwelitye elibambeneyo okanye lesakhiwo sogwebu elenziwe yimagma evela kwintaba-mlilo emva kokupholisa phezu komhlaba.Yeyamagmatic rock.Ulwakhiwo lwawo lwamatye luhlala lubonisa i-stomatal, efana nealmond, kunye nezakhiwo ze-porphyritic, ngamanye amaxesha zineekristale ezinkulu zamaminerali.I-basalt engenaweathered ubukhulu becala imnyama kunye nengwevu, kwaye kukwakho nomdaka omnyama, omfusa omnyama, kunye noluhlaza ongwevu.

I-basalt ye-Porous (i-pumice), ngenxa yokuphakama kwayo okuphezulu kunye nobunzima obuninzi, inokuxutywa kunye nekhonkrithi ukunciphisa ubunzima bayo, kodwa isenamandla kwaye ineempawu ezifana nokugquma isandi kunye nokufudumala ukushisa.Yiaggregate efanelekileyo yekhonkrithi ekhaphukhaphu kwizakhiwo eziphakamileyo.I-Pumice iseyinto efanelekileyo yokugaya, engasetyenziselwa ukugaya isinyithi kunye nezinto zamatye;Kwimizi-mveliso, inokusetyenziswa kwakhona njengezihluzi, ezomisi, i-catalysts, njl njl.Iithayile zamatye ze-volcanic zendalo ze-lava kunye nelitye le-basalt ezithengiswayo.
