Plotting Mineral Compositions, and Chemographic Projections
Minerals and rocks have chemical compositions that comprise some of the most important data for phase equilibria studies. Important relationships among rocks and minerals can be discovered or demonstrated by the construction of composition diagrams (also called chemographic diagrams) to display the data.

First, I gather a collection of different rocks (Igneous, Metamorphic, and Sedimentary). Luckily, my school's media center has a rock collection. All of the rocks are labeled with name and type. Then, I assign each student a rock. For lower ability or ESL students, I assign igneous rocks they are the easiest to tell where/how they originated.

An unconformity represents a contact where beds of rock of different ages meet, instead of a continuous history. The structure of a slope is called its strike and dip. Geologists draw these symbols on maps to define the way beds of rock are at angles, or the way they are dipping. Strike and dip are at right angles to each other.
