Show your calculations and plot each rock on the appropriate blank classification diagram on the back of this page. Label your plotted points with the corresponding question number and label the corners of the diagram. 4. While mapping in the Ariège region of the French Pyrenees, you discover an outcrop of an unusual igneous rock. The rock is quite coarse-grained and is dark colored with patches of dark green, due to abundant olivine. You estimate that the rock contains approximately 50% olivine, 45-50% pyroxene, and no more than about 5% garnet. In thin section, the pyroxene is identified as mostly orthopyroxene (about 30% of the rock), but there's also considerable clinopyroxene present (15-20% of the rock).
