Igneous Rock Classification Pdf Igneous Rock Lava Igneous rocks form when magma cools and solidifies either underground or on the earth's surface. they occur in various forms such as lava flows, domes, and intrusive bodies. igneous rocks are classified based on their mineralogy, texture, and chemical composition. Textural classification of igneous rocks phaneritic: crystals visible with naked eye plutonic or intrusive rocks aphanitic: crystal too small for naked eye.

Classification Of Igneous Rocks Pdf Igneous Rock Petrology In general, it should be possible to classify a rock from features observable in a hand specimen or thin section; it should not be necessary to see field relationships. Igneous rocks are formed through the cooling and solidification of magma or lava. they are classified into two main types: intrusive and extrusive, depending on where they solidify. these rocks are an essential part of the earth's crust and play a significant role in geological processes. Classification of igneous rocks figure 2.2a. a classification of the phaneritic igneous rocks: phaneritic rocks with more than 10% (quartz feldspar feldspathoids). Basic classification scheme for igneous rocks on their mineralogy. if the approximate volume fractions of minerals in the rock are known the rock name and silica content can be read off the diagram.

Basic classification scheme for igneous rocks on their mineralogy. if the approximate volume fractions of minerals in the rock are known the rock name and silica content can be read off the diagram. Igneous rock forms through the cooling and solidification of magma or lava. it is classified based on several properties including genesis, texture, color, and chemical composition. Formation of igneous rocks 1. below the earth surface, from slowly cooling of magma types: intrusive or plutonic – cools underneath examples: granite, diorite, and syenite formation of igneous rocks 2. Igneous rocks form when magma or lava cools and solidifies. there are two main types intrusive rocks, which form underground from cooling magma, and extrusive rocks, which form above ground from lava. Describe the three major compositional groups of igneous rocks basaltic – dark in colour and tend to have low levels of silica. intermediate – contain both light and dark colored minerals. granitic – light in colour and tend to have high levels of silica.
