Rocks on a school textbook

These are specimens of some of the more typical rocks covered in junior and senior high school textbooks in Japan. The exhibit also includes minerals which correspond to the diagrams of polymorphs that appear in "Classification of igneous rocks on the basis of bulk rock chemistry," and "Pressures and temperatures of metamorphism." In addition to merely learning the names of these rocks from textbooks, please examine and acquaint yourselves with the actual minerals and rock specimens.
