Instructions
Introduction
Igneous rocks are rocks that solidify from molten material (magma). Cooling of the magma can occur beneath the surface (plutonic) or on the surface (volcanic). Igneous rocks can be identified by the determination of the composition and texture of the rock. Once these two characteristics have been identified, the Igneous Rock Identification chart is used to identify the rock name.
On each of the following pages, you will find an image of a rock and an Igneous Rock Identification Chart. Identify the composition by identifying the color and determine the texture by examining the crystal sizes that are present. Once this is done the rock name is easily determined using the Classification of Igneous Rock chart.
Here you will find your Igneous Rock Identification Chart which defines the physical properties and provides the means for determining the physical property of a mineral sample.
