Schist is a medium-grade metamorphic rock with medium to large, flat, sheet-like grains in a preferred orientation (nearby grains are roughly parallel). It is defined by having more than 50% platy and elongated minerals, often finely interleaved with quartz and feldspar. These lamellar (flat, planar) minerals include micas, chlorite, talc, hornblende, graphite, and others. Quartz often occurs in drawn-out grains to such an extent that a particular form called quartz schist is produced. Schist is often garnetiferous. Schist forms at a higher temperature and has larger grains than phyllite. Geological foliation (metamorphic arrangement in layers) with medium to large grained flakes in a preferred sheetlike orientation is called schistosity
Rhyolite is a type of extrusive igneous rock characterised by its light color, high silica content, and fine-grained texture. It forms from the rapid cooling of magma on the Earth's surface and is often associated with volcanic eruptions. Rhyolite is rich in silica (SiO₂), typically containing more than 70% silica. It is composed mainly of quartz and feldspar, with minerals like biotite, hornblende, and pumice often present.

The Sainte-Victoire mountain is a limestone massif in the South of France, in the Provence-Alpes-Côte d'Azur region. Located east of Aix-en-Provence, it has enjoyed international notoriety in part thanks to the sixty works of the painter Paul Cézanne of which it is the object. It is home to many hikers, climbers and nature lovers, and is a major part of the Aix landscape.
