Ch. 5 Igneous rocks Earth Science
Bowen's reaction series
sequential, predictable, dual-branched pattern in which minerals crystallize from cooling magma
fine-grained igneous rocks that cool quickly on Earth's surface
the process wherein different minerals form at different temperatures
formed from the crystallization of magma
coarse-grained rocks that cool slowly beneath Erath's surface
magma that flows out onto the Earth's surface
the process whereby some minerals melt at low temperatures while other minerals remain solid
light-colored rocks that have high silica content and contain quartz and the feldspars orthoclase and plagioclase
rare ultramafic rock that can contain diamonds and other minerals formed only under very high pressures
dark-colored rocks that have low silica content and are rich in iron and magensium.
vein deposits of extremely large-grained minerals that contain rare ores such as lithium and beryllium
rock texture characterized by large, well-formed crystals surrounded by finer-grained crystals of the same material
igneous rocks with low silica content and very high levels of magnesium and iron.
