Lava: molten rock that flows out onto the earth’s surface. Rocks that crystallized directly from a melt. Igneous rocks . Form as magma cools and crystallizes . Rocks formed inside Earth are called . plutonic. or intrusive rocks . Rocks formed on the surface . Syenite, Phonolite, . Ijolite. , Carbonatite, Ultramafic Rocks and Lamprophyre. 2. IUGS Intrusive Igneous Rock Chart . 3. General Intrusive Rocks Classification. . 4. Position on IUGS Diagram. Syenites are on the border between the QAP and the APF triangles. Rocks are composed of two or more minerals. Rocks are very helpful in dating the age of the earth. Classification of Rocks. Igneous rocks. Sedimentary rocks. Metamorphic rocks. Igneous Rocks.

As magma cools underground, it will begin to solidify within Earth’s crust.. Once completely crystallized, these masses of igneous intrusive rock are referred to as INTRUSIONS or as PLUTONS. We will talk about several types of igneous . CLASSIFICATION OF ROCKS:. ON THE BASIS OF MODE OF FORMATION ROCKS ARE CLASSIFIED INTO THREE CATEGORIES:. 1 IGNEOUS ROCKS. 2 SEDIMENTARY ROCKS. 3 METAMORPHIC ROCKS.  . ROCKS. IGNEOUS ROCKS:.  . IGNEOUS ROCKS, ALSO KNOWN AS PRIMARY ROCKS ARE FORMED BY SOLIDIFICATION OF MAGMA. MAGMA IS MOLTEN ROCK MATERIAL CONSISTING OF LIQUID,GAS AND CRYSTAL.IGNEOUS ROCKS ARE RECODS OF THERMAL HISTORY OF EARTH..
