Slate and phyllite are both types of foliated metamorphic rocks. Metamorphic rocks are rocks which have been transformed by heat and pressure within the Earth’s crust. Both slate and phyllite are formed in similar ways, phyllite, however, is subjected to even higher temperatures and greater pressures than slate, which causes the clay within the material to break down and form mica. The mica in phyllite are larger than in slate and are visible as a sheen on the material’s surface.
Slate vs phyllite – qualities and characteristics
At SSQ, we mine, produce, and supply, high-quality roofing materials made from both slate and phyllite. SSQ slate is mined from sustainably run quarries in a respected slate-producing area in Northern Spain. From there, it is shipped around Europe for use as a high-quality roofing material. SSQ phyllite is mined from the SSQ-owned Riverstone quarry in Argentina. From here it undergoes rigorous quality checks before being shipped around the world.
Both SSQ Spanish slate and Riverstone phyllite can be used to create stunningly attractive and extremely durable and weather-resistant roofs.
