[G04-09] Problems concerning the classification of igneous rocks dealt with in earth science education -A practical educational program using cumulate rocks-
Keywords:Igneous rocks, Ultramafic rocks, Cumulate
Education of earth sciences deals with the classification of the igneous rocks based on modal and chemical compositions. Plutonic rocks, however, do not necessarily represent magma composition. We propose a practical educational program for verification of classification of the igneous rocks by using ultramafic rocks of drill cores from NE Japan.
