From 16 km along the road from Noqui to Sao Salvador, Holmes (1915) described a riebeckite-aegirine granite marginal to albite granites. A mode, by weight, gave 32% quartz, 48% albite, microcline and perthite, 16% riebeckite, 4% aegirine and accessories including zircon. A rock analysis is given. This locality extends northwards into Congo (See Congo No. 20).
