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
. All this portion of Bundelcund, which is little frequented by travellers, is inhabited by a fanatical population, hardened in the most horrible practices of the Hindoo faith.
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
. Its appearance was rather pretty.
Geology and petrology of felspathoidal syenites
and associated rocks of Koga area, Chamla valley, Swat, West Pakistan.
The bedrock at Zagi Mountain is part of the Warsak igneous complex (Ahmand et al., 1969; Kempe, 1973; Khan, 1990), which is itself part of the Peshawar plain alkaline igneous province, a group of alkaline granites, syenites
and nepheline syenites
which crop out around the margins of the Peshawar basin.

(1992) The regional geology of the Pocos de Caldas alkaline complex: mineralogy e geochemistry of selected nepheline syenites
They are LREE-enriched peralkalic syenites
and alkalic syenitoids with potassium feldspar, plagioclase, quartz, biotite and aegirine-augite as their common minerals.
The majority of zeolite occurrences described here are in rocks within or adjacent to the Central Metasedimentary Belt (CMB) of the Grenville Province, probably an ancient island arc, composed largely of Precambrian marbles, gneisses, amphibolites, granites, syenites
, etc., formed by tectonic and plutonic mountain-building events (Grenville orogeny) at ~950-1080 Ma, during which amphibolite-to-granulite facies conditions were attained.
Most of the rocks in the study area include syenites
, feldspathoidal syenites
, fenites, carbonates and associated rocks(Siddique, 1965, 1967).
Quartz-apatite-magnetite rocks, carbonatite, and syenites
are some other significant rocks reported from Beldih region [9-12].
For more than a century, at a myriad of collecting sites in the small stream drainages which decline to the Rhone in Tujetsch, crystallized clefts in gneisses, granodiorites, syenites
and aplites have yielded minerals of the Fundortgruppe 3 paragenesis of Parker (1973).
