Usage
When polished, trachyte is often used as a decorative construction material, often as flooring or countertops or even tombstones. It is also suitable for constructing walls and can be found as the foundational stone for many houses. This attractive stone may also be carved for use in statues and monuments.
Composition
Trachyte has a silica content of 60 to 65% and an alkali oxide content of over 7%. This gives it less SiO2 than rhyolite and more (Na2O plus K2O) than dacite.
