Fine crystalline, pure calcite.

Perfect for Introductory Lessons on Metamorphic Rocks.

Phyllite is a light-gray foliated rock formed from metamorphosed slate.

Fightly cemented, medium-to-coarse quartz grains.

Chlorite-mica with perfect slaty cleavage.

Includes: six each of marble, slate, and quartzite. Set of 18.

Common rocks and minerals for testing and identification studies are 2–3cm each.

White and black bands of quartz, feldspar, and biotite; typical foliation.
