Igneous rocks are classified based upon their

v. Categorizing Metamorphic Rocks: Metamorphic rocks are often classified into foliated and non-foliated rocks – a criteria based on their appearance. Foliated rocks have a banded or layered appearance because the minerals within the rock are in parallel alignment. They include schist, gneiss and slate. Igneous rocks comprise one of the three principal classes of rocks, the others being metamorphic and sedimentary rocks. Though they vary widely in composition, most igneous rocks consist of quartz, feldspars, pyroxenes, amphiboles, micas, olivines, nepheline, leucite, and apatite. They may be classified as intrusive or extrusive rocks.

Metamorphic rocks are changed rocks. Which of the following rock types could be the "parent" of a metamorphic rock? Earth materials always trace the complete rock cycle from sediment through igneous rocks.

Rocks and Minerals: After given initial knowledge of different mineral and rock types, students determine whether a set of samples are rocks or minerals. Igneous Rocks: Melting salol crystals and then allowing the mixture to cool at variable rates will show the students how igneous rocks are formed in different locations. The different mixtures represent intrusive and extrusive igneous rock formation.
