The word Syenite may not be common like Gold, Copper and Lead in Nigeria, West Africa but it is one of the naturally found mineral resources that possess almost the same look like granite and can be mistaken for granites sometimes. 
The mineral deposit of Syenite in Nigeria is in small quantity and can be seen in Ekiti State. It is characterised as an igneous rock with a coarse-grained structure similar to that of granite. 

Syenites are composed of alkali elements like feldspar, also ferromagnesian minerals, and earth-alkali elements mainly potassium, sodium and calcium.
To get a syenite, the igneous or granitic rock is partially melted to a relatively low degree; this is because of the presence of potassium, calcium and sodium, which will melt away respectively as the temperature degree gets higher which leaves behind plagioclase, granite, adamellite and nepheline syenite.
During the low temperature melting, anorthite crystals may likely in a larger volume precipitate precipitate from molten magma and gradually settles and bonds as it cools down leaving behind the remaining melt particles which has silica in a very low concentration. The separation of the silica away from the melt increases the possibility of syenite to form.
 
The mining of Syenite in Nigeria may not be enough for exportation to other African countries or internationally but it will help the indigenous industries to have an access to more industrial raw materials as it is one of the primary needs of the building and construction companies in Nigeria.

Uses of Syenite

• Syenite, like granites, is used in buildings, bridges, paving, monuments etc., either as a crushed stone or aggregate.
• It is also used in tile floors, countertops, stair treads etc, when it is cut into tiles and slabs.
