Igneous Rocks in Geologic Maps
Igneous rocks are important components to many terranes around the world. Igneous rocks are displayed on many different geologic maps, including many in Arizona. Let's look more closely at igneous rocks in two geologic maps: the Geologic Map of Arizona and the Geologic Map of the Cordes Area in Yavapai County, Arizona (near Prescott).
