This sand is from the Big Sur coast of California, with many metamorphic rocks created near an ancient subduction zone. The sand on the right is 100% composed on shells, coral skeleton, and other biological precipitates.
Schist is a coarse grained metamorphic rock. If you look at a piece of this metamorphic rock you will be able to see crystals of the minerals that make up the rock. It comes from shale or at least at one time it was shale. So geologists say that shale is the parent rock. It is made up of clay minerals. Shale can metamorphose into slate, phyllite, schist or gneiss depending on the degree of heat and pressure. Schist has a greater degree of metamorphism than phyllite but less than gneiss. It is classed as a medium-grade metamorphic rock and is associated with regional metamorphism do to mountain building.
