COARSE WHITE MARBLE | Marble is a metamorphic rock formed from limestone. The high-pressure, low-heat alteration leads to a massive crystalline ro...

ANTHRACITE COAL | Anthracite coal is bright and reflective, indicative of the intense heat and pressure required to form it. Anthracite coal often...

GARNET SCHIST | A metamorphic rock that has undergone moderate levels of alteration, schist is good for demonstrating the effect of metamorphism o...

GREEN SLATE | Slate is very lightly metamorphosed and well-foliated. This appearance often makes it difficult to distinguish from its parent rock,...

PHYLLITE | Phyllite is a good example of low-grade metamorphism from an easily recognizable parent rock. The fissile property of slate is retained...

WHITE QUARTZITE | Quartzite is formed from sandstone that has been tightly compressed to the point where the clasts have recrystallized to form a ...

MICA SCHIST | A metamorphic rock that has undergone moderate levels of alteration, schist is good for demonstrating the effect of metamorphism on ...

SERPENTINITE | When clay- and aluminum-rich rock is altered by water from geothermal systems, serpentinite is liable to form. Often found in low-g...
