Copses of dates and dwarf-palms succeeded the dense forests; then vast, dry plains, dotted with scanty shrubs, and sown with great blocks of syenite
It was then passing over Mabunguru, a stony country, strewn with blocks of syenite
of a fine polish, and knobbed with huge bowlders and angular ridges of rock; conic masses, like the rocks of Karnak, studded the soil like so many Druidic dolmens; the bones of buffaloes and elephants whitened it here and there; but few trees could be seen, excepting in the east, where there were dense woods, among which a few villages lay half concealed.
Not far from Monte Video we passed through the village of Las Pietras, so named from some large rounded masses of syenite

The Tajno massif is composed of alkaline rocks ranging from syenite
to pyroxenite, cut by carbonatite veins (Krystkiewicz & Krzeminski 1992; Ryka 1992; Ryka et al.
Among the additives options that prevent thin plastic layers from sticking to each other, 'Talc, nepheline syenite
, and DE have been the incumbent high-performance antiblock minerals in plastic films," says John Flurley, president and CEO of Trinity Resources.
