The Mbalevuto sill intrudes sedimentary rocks on the SW flank of Tavua volcano, Viti Levu, Fiji. It appears to have been intruded at shallow depth in a semi-molten state. The sill is of essexitic composition and petrochemical evidence suggests that magmas forming the sill and lavas of the Tavua volcano are consanguineous.
