Zulia is a syenite intrusion forming a hill close to the international boundary ‘triple point’ with Sudan and Kenya. Smith (1938) describes a loose boulder from the foot of the hill as a ‘hornblendic quartz syenite rich in microperthite’, which does not sound particularly alkaline. No other petrographic details have been traced.
