syenite

noun ˈsʌɪənʌɪtˈsaɪəˌnaɪt

mass nounGeology

A coarse-grained grey igneous rock composed mainly of alkali feldspar and ferromagnesian minerals such as hornblende.
Example sentencesExamples
- The selective removal of these minerals resulted in a change of the composition of the magma to one near that of the rock syenite.
- The province is also endowed with other non-traditional minerals including nickel, feldspar, emerald, limestone, granite, amethyst, sodalite and syenite.
- Originally, the syenite was barged, until about 1949 when it was hauled by truck 24 miles to the CNR at Lakefield, which distance was only slightly farther than the CPR had to build.
- A violet, coarse-grained, porphyritic quartz syenite, which makes up large parts of the pluton, was collected for dating.
- The southern Zomba area consists mainly of syenite surrounded by a periphery of alkaline granite.

Example sentencesExamples
- In the central part of the intrusion, some small granitic aplite dykes intrude the syenitic rocks.
- Of far less importance are occurrences in gneisses and amphibolites, in small plutons derived from syenitic and gabbroic magmas, and in certain contact-metamorphic rocks.
- During the early Gardar period, around 1350 Ma, basaltic lavas were erupted and syenitic plutons were emplaced.
- Other basaltic units and syenitic intrusions with ages 0.56 to 0.55 Ga are widely distributed.

Origin

Late 18th century: from French syénite, from Latin Syenites (lapis) '(stone) of Syene' (from Greek Suēnē Aswan in Egypt).
