lava magma that flows out onto Earth's surface.
igneous rock intrusive or extrusive rock formed from the cooking and crystallization of magma or lava
partial melting process in which different minerals melt into magma at different temperatures, changing its composition.
Bowen's reaction series sequential, predictable, dual-branched pattern in which minerals crystallize from cooling magma.
fractional crystallization process in which different minerals crystallize from magma at different temperatures, removing elements from magma.
intrusive rocks coarse-grained igneous rock that is formed when molten rock cools slowly and solidifies inside Earth's crust.
extrusive rock fine-grained igneous rock that is formed when molten rock cools slowly and solidifies inside Earth's surface.
basaltic rock rock that is dark colored, has lower silica contents, and is rich in iron and magnesium; contains mostly plagioclase and pyroxene
grantic rock light-colored rock that has high silica content, and contains quartz and potassium feldspar
texture the size, shape, and distribution of the crystals or grains that make up a rock.
porphyritic texture rock texture characterized by large, well-formed crystals surrounded by finer-grained crystals of the same of different mineral
vesicular texture a spongy-looking rock; lava whose gas bubbles do not escape.
pegmatite vein deposits of extremely large-grained minerals that can contain rare ores such as lithium and beryllium
kimberlite Rare, ultramafic rock that can contain diamonds and other minerals formed only under very high pressures.
