Igneous rocks are rocks formed from the crystallization of a liquid (molten rock). Igneous rocks may be divided into two categories. Intrusive or plutonic rocks crystallize from magma beneath the earth’s surface. Extrusive or volcanic rocks crystallize from lava at the earth’s surface.
Fractional crystallization is a method of refining substances based on differences in solubility. … If a mixture of two or more substances in solution are allowed to crystallize, for example by allowing the temperature of the solution to decrease, the precipitate will contain more of the least soluble substance.
How do the crystallization and settling of the earliest formed minerals affect the composition of the remaining magma? After the earliest formed minerals have settled, the resulting magma will be more felsic than the original magma.
Terms in this set (9) igneous rocks that form as magma cools underground are called intrusive rocks. when lava cools and crystallizes, it becomes igneous rock.
What is the process that is thought to generate most granitic magmas? A basaltic pond of magma becomes trapped below continental crust and partially melts this silica-rich crust into a granitic magma.
Fractional crystallization: Process in which different minerals crystallize from magma at different temperatures, removing elements from magma.
Of the common silicate minerals, olivine normally crystallizes first, at between 1200° and 1300°C. As the temperature drops, and assuming that some silica remains in the magma, the olivine crystals react (combine) with some of the silica in the magma (see Box 3.1) to form pyroxene.
When magma flows or erupts onto Earth’s surface, it is called lava. Like solid rock, magma is a mixture of minerals. It also contains small amounts of dissolved gases such as water vapor, carbon dioxide, and sulfur. The high temperatures and pressure under Earth’s crust keep magma in its fluid state.
Most of the minerals in the Earth have crystallized from something called magma. … When magma cools, the chemical components join together to build minerals. The minerals join together to form a rock. Other minerals, like halite (table salt), form when water solutions dry out.
The means that the overall composition of the magma near the top of the magma chamber will become more felsic, as it is losing some iron- and magnesium-rich components. This process is known as fractional crystallization.
