    Igneous Rocks Pictures of Intrusive and Extrusive Rock Types

    Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff. Pictures and brief descriptions of some common igneous rock types are shown on this page.get price

    3 Main Types of Rocks and Their Properties

    Properties of Igneous Rocks. Different types of igneous rocks have different properties, but there are some general properties that help identify all igneous rocks. They all contain minerals. The majority are made up of silicate materials. The process of igneous rock formation cannot be directly observed. They can be fine-grained or close-grained.get price

    Igneous Rocks and the Rock Cycle

    Igneous Rocks Igneous rocks are formed by the cooling of molten rock. There are two major states of molten rock: Magma and Lava. Magma is a form of molten rock that exists below the Earth’s surface. Lava is the term given to magma once it reaches the Earth’s surface, usually in the form of a volcanic eruption. There are two major classifications of igneous rocks: Intrusive andget price

    Igneous Rocks Definition, Characteristics, Types

    Extrusive Igneous Rock. Extrusive igneous rocks are rocks that erupt onto the surface resulting in small crystals as the cooling takes place quickly. The cooling rate for a few rocks is so quick that they form an amorphous glass. Basalt, tuff, pumice are examples of extrusive igneous rock.
