What is Syenite Rock?
Syenite is a type of igneous rock. This means it formed when hot, molten rock, called magma, cooled down and became solid. Syenite looks a bit like granite, but it has less quartz. It often contains minerals like feldspar and hornblende. Because it's a strong and attractive rock, syenite has been used in building and construction for a long time.
