In General, Which of the Statements Below Best Describe What

question 10

Multiple Choice

In general, which of the statements below best describe what happens in terms of composition as crystallization proceeds down the Bowen's reaction series (shown in the figure) ?

• A)The early-formed silicates are enriched in iron and magnesium, resulting in such rocks as andesite and granite. As crystallization proceeds, the later-formed silicates are enriched in sodium, potassium, and silicon, resulting in peridotite and basalt.
• B)The early-formed carbonates are enriched in calcium and carbonate, resulting in such rocks as limestone. As crystallization proceeds, the later-formed carbonates are enriched in fossils, resulting in fossiliferous limestone and coquina.
• C)The early-formed silicates are enriched in iron and magnesium, resulting in such rocks as peridotite and basalt. As crystallization proceeds, the later-formed silicates are enriched in sodium, potassium, and silicon, resulting in andesite and granite.
• D)The early-formed silicates are enriched in sodium, potassium, and silicon, resulting in such rocks as peridotite and basalt. As crystallization proceeds, the later-formed silicates are enriched in iron and magnesium, resulting in andesite and granite.
