An oval-shaped intrusion 4x2.5 km in diameter, Ubari forms a hill cutting Precambrian biotite gneisses. The predominant rock type is a syenite of perthite, aegirine-augite and biotite. There is a little quartz together with apatite, sphene and magnetite. Eckermannite-bearing rocks are thought to be fenites.
