Study Notes
Igneous Rock Formation
- Igneous rocks are formed when magma cools beneath Earth's surface through a process called plutonism.
- Magma cooling beneath Earth's surface results in larger crystals because the magma cools slowly, allowing minerals to grow larger.
Bowen's Reaction Series
- Bowen's reaction series is primarily concerned with the order of mineral crystallization from magma.
- Norman Bowen hypothesized that the main factor influencing the occurrence of certain minerals together in igneous rocks is the temperature of magma.
- Bowen conducted experiments with igneous rocks by heating and cooling them to simulate natural geological processes.
- Bowen's reaction series explains the order of mineral crystallization from magma, with minerals crystallizing at higher temperatures first.
Mineral Crystallization
- In Bowen's reaction series, minerals crystallize in a specific order, with olivine crystallizing at the highest temperatures in the discontinuous series.
- The mnemonic "Olive Pits Are Bitter" can be used to remember the order of minerals in the discontinuous series.
- In the continuous series, the primary mineral involved at the highest temperature is calcium-rich plagioclase.
Magmatic Differentiation
- Magmatic differentiation is primarily concerned with the process of magma differentiation and the resulting changes in mineral composition.
- During magmatic differentiation, crystals settle out of the magma, resulting in a change in the magma's composition.
- The result of magmatic differentiation is a change in the mineral composition of the resulting igneous rock.
- Magmatic differentiation explains the variation in mineral composition between different igneous rocks.
Bowen's Reaction Series Diagram
- The Bowen's reaction series diagram depicts the order of mineral crystallization from magma.
- The diagram shows the discontinuous and continuous series of mineral crystallization.
