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?
Olivine is the first mineral to crystallize as the mineral first to crystallize is the last to melt.
Why can minerals that form early in fractional crystallization grow distint?
They form more euhedral shapes because they are the first to crystallize, and don't have to compete for room.
How does fractional crystallization lead to magmatic differentiation?
As a magma crystallizes it undergoes fractional crystallization in which mafic minerals crystallize first and felsic minerals crystallize last. Therefore, as fractional crystallization occurs the magma becomes increasingly less mafic and increasingly more felsic. The viscosity also increases as a magma becomes more felsic.
Which mineral crystallize first from magma?
Sulphur

What would be one of the first minerals to crystallize from liquid rock in a mafic igneous sill?
Olivine
What is Bowen's reaction series?
Bowen's Reaction scale lists the order in which minerals crystallize. Olivine or ultramafic minerals are the first to crystallize. They do so at high temperatures, whereas quartz is the last to crystallize, and at low temperatures. Through Bowen's many studies, he found that the order of magma from high to low temperature is ultramafic, mafic, intermediate, and felsic. Plagioclase feldspar follows the crystallization of olivine.

Who discovered minerals?
Olivine... if you can find on the internet the "Bowens Reaction Series" paper, it will tell you that Olivine is the first to crystallize
The first feldspars to form are rich in what element?
calcium
First to crystallize a virus?
Wendell Stanley
Which mineral crystallize first from magma?
Sulphur
Do rocks with higher melting points crystallize first?
yes
How is partial melting related to fractional crystallization?
Partial melting occurs in rocks because the different minerals that compose rocks have different melting points. For example, felsic minerals (e.g. quartz and feldspar) melt at around 700 degrees Celsius while mafic minerals (e.g. pyroxene and olivine) melt at around 1200 degrees Celsius. Therefore, felsic minerals will melt first leaving the mafic minerals solid.Fractional crystallization occurs when minerals from a magma cool and crystallize out of the magma. The first crystals to melt in partial melting will be the first minerals to crystallize out when the magma begins to cool. Therefore, mafic minerals will crystallize first, followed by felsic minerals.Both partial melting and fractional crystallisation tend to produce a more felsic magma than their source rocks.The difference is simply that they are the reverse of one another, heat it up, cool it down. Things that melt first solidify last and separate from one another.
