Please read over the questions carefully and answer the questions and label the corresponding diagram (attached image 1). (I have also added a closer up image of the bottom left diagram (image 2). 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. 1. You're studying a uniformly fine-grained (1-2mm) igneous rock. Your point-count modal analysis of a thin section indicates 30.6% plagioclase, 28.9% quartz, 25.5% microcline, 8.2% muscovite, and 5.8% biotite. Collectively, zircon and apatite (accessory minerals) make up only 1.0% of the rock.
