How does iron - magnesium and feldspars crystallize from magma?
Feldspars are the first to crystallize at the eutectic point after which the temperature drops, thus crystallizing the iron - magnesium.
What is the first minerals to form when magma cools that are rich in iron calcium and magnesium?
The first minerals to form when magma cools and is rich in iron, calcium, and magnesium are typically olivine, pyroxene, and/or plagioclase feldspar. These minerals have high melting points and tend to crystallize early as the magma cools.
Why gabro color is black?
The igneous rock gabbro is black because its composition is mafic. Mafic rocks are low in silica and very high in magnesium and iron. It is the magnesium- and iron-rich content that causes its color to be black.
What type of magma would you expect to see after crystallization of minerals containing significant amounts of iron?
The type of magma you would expect to see after crystallization of minerals containing significant amounts of iron is likely basaltic magma. This is because minerals with higher iron content tend to form in basaltic magmas, which are rich in iron and magnesium.
What is the igneous rock that is dense and dark colored and forms from magma that is rich in iron and magnesium but poor in silica That has 8 letters?
The igneous rock you are referring to is basalt. It is a fine-grained, dense, and dark-colored rock that forms from low-silica magma rich in iron and magnesium.

Compare the ways in which ironmagnesium minerals and feldspars crystallize from magma?
In Bowen's reaction series, feldspar minerals go through a continuous change of composition, while iron-magnesium groups have an abrupt change of mineral types. When magma cools, the feldspars that form are calcium-rich. As cooling continues, the feldspars react with magma and the feldspar composition changes. The result is a zoned crystal with sodium-rich outer layers and calcium-rich core. For iron-magnesium minerals, when magma starts cooling, a mineral begins to crystallize. However, when the magma temperature drops, a whole new mineral begins to form. The previously formed minerals reacts with the magma and is converted into the new mineral.
What are the common elements in magma?
Silicon, aluminum, magnesium, iron.
Dense heavy dark-colored igneous rocks form from what magma?
Dense heavy dark-colored igneous rocks form from mafic magma, which is rich in iron and magnesium and has a relatively low silica content. This type of magma tends to crystallize into minerals like pyroxene, olivine, and amphibole, resulting in rocks like basalt or gabbro.
Why gabro color is black?
The igneous rock gabbro is black because its composition is mafic. Mafic rocks are low in silica and very high in magnesium and iron. It is the magnesium- and iron-rich content that causes its color to be black.

Can minerals crystallize out of magma when it melts?
Yes, minerals can crystalize when magma melts.
What process is required for minerals to crystallize to magma?
Minerals in magma crystallize through the process of cooling and solidification. As magma cools, atoms and ions within the molten rock arrange themselves into an ordered, repeating three-dimensional pattern, forming mineral crystals. The specific minerals that crystallize depend on factors such as temperature, pressure, and chemical composition of the magma.
What is the igneous rock that is dense and dark colored and forms from magma that is rich in iron and magnesium but poor in silica That has 8 letters?
The igneous rock you are referring to is basalt. It is a fine-grained, dense, and dark-colored rock that forms from low-silica magma rich in iron and magnesium.
What does more iron and magnesium make magma?
More iron and magnesium in magma can make it more dense and viscous. This can result in a thicker magma that is less likely to flow easily. It may also affect the melting temperature and can influence the type of volcanic eruptions that occur.
Do minerals crystalize out of magma when it melts?
No. Magma is already at least partially molten. Mineral crystallize when magma solidifies.
