— Anorthosite is a type of igneous rock that is primarily composed of a mineral called plagioclase feldspar. It is known for its distinctive light-colored appearance, often characterized by a white to light gray coloration. Anorthosites are an important rock type in the field of geology due to their unique composition and geological significance.

— Igneous Rock Composition. Composition refers to a rock's chemical and mineralogical make-up. For igneous rock, the composition is generally divided into four groups: ultramafic, mafic, intermediate, and felsic. These groups refer to differing amounts of silica (SiO 2), iron (Fe), and magnesium (Mg) found in the minerals that make up the …

4.1.3 Igneous Rock Bodies. Igneous rocks are common in the geologic record, but surprisingly, it is the intrusive rocks that are more common. Extrusive rocks, because of their small crystals and glass, are less durable. Plus, they are, by definition, exposed to the elements of erosion immediately. Intrusive rocks, forming underground with larger, …

Intrusive and Extrusive Igneous Rocks. Igneous rocks are called intrusive when they cool and solidify beneath the surface. Intrusive rocks form plutons and so are also called plutonic. A pluton is an igneous intrusive rock body that has cooled in the crust. When magma cools within the Earth, the cooling proceeds slowly.

— Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, …

Igneous rocks are of two types, intrusive (plutonic rocks) and extrusive (volcanic rocks). Intrusive igneous rocks are formed when the magma cools off slowly under the earth's crust and hardens into rocks. Gabbro and granite are examples of intrusive igneous rocks. Rapid cooling results in smaller crystals while slow cooling results in large ...
