Between 1 and 1.5 billion years ago, a supercontinent broke apart on Earth, forming the Sedimentary Basins. Dunes formed by quartz grains rose up and were transformed into quartzite by metamorphism, bringing soft lines drawn by opaque minerals, rutile, tourmalines and green muscovite that decorate its crystalline mass in light gray shades, as well as veins of white quartz that spread across its layers. 
Straight from Serra Mineira, Denali is a robust and timeless quartzite that reveals its history in the preserved sedimentary formations.
