Geology For Beginner: Rock Types

Igneous rocks are formed from the solidification of molten rock material. There are two basic types: 1) intrusive igneous rocks such as diorite, gabbro, granite and pegmatite that solidify below Earth's surface; and 2) extrusive igneous rocks such as andesite, basalt, obsidian, pumice, rhyolite and scoria that solidify on or above Earth's ...

Introduction to Rocks — [email protected]

Most rocks on Earth are ultimately derived from magma or lava that cooled to form, respectively, extrusive or intrusive igneous rocks. (Exceptions include chemical and organic sedimentary rocks). For example, most of the grains that form beach sand (which might one day become sandstone) are derived from weathered and eroded igneous rock.

Types of Rocks - West Allegheny School District

It is an intrusive rock, meaning that it crystallized from magma that cooled far below the earth's surface. G ranites usually have a coarse texture (individual minerals are visible without magnification), because the magma cools slowly underground, allowing larger crystal growth. It is the most common igneous rock.

DK Science: Rocks - Fact Monster

Magma loses heat when it moves upwards at weak spots, such as cracks, in the crust. Extrusive igneous rocks form when magma reaches the surface and cools quickly. Fast cooling produces fine-grained rocks. Intrusive igneous rocks form when magma cools slowly underground. This allows the minerals to grow into coarse grains.

What is the texture of intrusive igneous rocks ...

If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. The slow cooling process allows crystals to grow large, giving the intrusive igneous rock a coarse-grained or phaneritic texture. The individual crystals in phaneritic texture are readily visible to the unaided eye.
