Babban albarkatun kasa don laka na teku shine sepiolite foda, wanda shine ma'adinin magnesium silicate yumbu mai hydrated wanda yake da tsabta, maras guba, maras wari, kuma maras radiyo.Yana da mafi girman yanki na musamman a cikin ma'adanai marasa ƙarfe (mafi girman Har zuwa 900m2 / g) da tsarin pore na musamman na abun ciki, an gane shi azaman ma'adinin yumbu mafi ƙarfi.

Wasu daga cikin abubuwan da ke sama na sepiolite (kamar raunin acidity na saman, maye gurbin ions na magnesium tare da wasu ions, da dai sauransu) ya sa shi da kansa yana da amfani a matsayin mai kara kuzari ga wasu halayen.Saboda haka, sepiolite ba kawai mai kyau adsorbent amma kuma mai kyau mai kara kuzari da mai kara kuzari.
