Activity 5.4 Minerals That Form Igneous Rock Name: Course/Selection: Learning GOAL You will identify specimens of several different minerals that are common in igneous rock. Being able to recognize the most important minerals in common igneous rock types is an essential skill used in classifying igneous rocks. augite (pyroxene) olivine A Use information from the section "Composition of Common Igneous Rocks" to identify the minerals in Fig. A5.4.1. Below each picture, write the name of the mineral, its chemical composition (chemical formula or chemical name), and a description that would allow you to recognize it in the future. All samples are shown at approximately their actual size. hornblende (amphibole) biotite mica sodium-rich plagioclase feldspar potassium-rich alkali feldspar 2 Date: 5 3 muscovite mica quartz
