Chapter 5 Igneous Rocks What Are Igneous Rocks As shown in table 5 2, the three main groups of igneous rocks— felsic, mafic, and intermediate—are classified according to their mineral compositions. felsic rocks such as granite are light colored, have high silica contents,and contain quartz and the feldspars ortho clase and plagioclase. Igneous rock texture if magma cools slowly, deep within the crust on the "interior" of the earth, the rock is called intrusive or plutonic. the slow cooling process allows crystals to grow large, giving intrusive igneous rock a coarse grained or phaneritic texture. the individual mineral crystals are visible to the unaided eye. if lava cools quickly, on the surface or on the "exterior" of the.

This discussion centers on key concepts, including the classification of igneous rocks into intrusive and extrusive types, based on their formation process and crystal size. Mineral composition of igneous rocks • when magma cools and crystallizes below earth’s surface, intrusive rocks form. • lava that cools and crystallizes on earth’s surface forms extrusive rocks. • igneous rocks are classified by their mineral compositions and there are four basic types. Classification of igneous rocks: this diagram shows the percentages of minerals, as well as the textures of common igneous rocks. for example, an aphanitic (fine grained) rock of mostly calcium rich plagioclase and pyroxene is basalt. 2) extrusive rocks or volcanic rocks when magma does reach the surface during a volcanic eruption, the rocks that form there are called lavas or volcanic rocks. the basic classification is the same as for plutonic rocks: with increasing silica content, they include: basalt, andesites, dacites, rhyolite, pumice and obsidian.
