• What Are the Properties of Igneous Rocks Sciencing

    Igneous rock, also known as volcanic rock, is formed by the cooling of magma or lava. This type of rock is classified by cooling time and the type of magma it is formed from. The properties of these rocks vary greatly, including their chemical composition, grain structure, texture and color.

    Geological SettingClassificationMineralogical ClassificationOccurrence of igneous rocks can be either intrusive (plutonic) or extrusive (volcanic). Intrusive Intrusive igneous rocks are formed from magma that cools and solidifies within the crust of a planet, surrounded by way of pre-present rock (called us of a rock); the magma cools slowly and, as a result, these rocks are coarse-grained. The mineral grains in such rocks can generally be recognized with the bare eye. Intrusive rocks also can be categorized consistent with the shape and size of the intrusive body and its relation t

    Igneous rock, any of various crystalline or y rocks formed by the cooling and solidification of molten earth material.Igneous rocks constitute one of the three principal classes of rocks, the others being metamorphic and sedimentary.. Igneous rocks are formed from the solidification of magma, which is a hot (600 to 1,300 °C, or 1,100 to 2,400 °F) molten or partially molten rock material.

    Rock Rock Mechanical properties: When a stress σ (force per unit area) is applied to a material such as rock, the material experiences a change in dimension, volume, or shape. This change, or deformation, is called strain (ε). Stresses can be axial—e.g., directional tension or simple compression—or shear (tangential), or all-sided (e.g., hydrostatic compression).

    A pluton is an igneous intrusive rock body that has cooled in the crust. When magma cools within the Earth, the cooling proceeds slowly. Slow cooling allows time for large crystals to form, so intrusive igneous rocks have visible crystals. Granite is the most common intrusive igneous rock.Igneous rocks make up most of the rocks on Earth.

    (2) Igneous rocks are granular or crystalline rocks but there are much variations in the size, form and texture of grains because these properties largely depend upon the rate and place of cooling and solidi­fication of magmas or lavas. For example, when the lavas are quickly cooled down and solidified at the surface of the earth, there is no
