What mineral tends to form first in bowen's series?
Olivine
What mineral tends to form last in Bowen's series?
Quartz.
Is amethyst an rock or mineral?
Amethyst is a mineral, a form of quartz.
How are minerals formed in igneous and metamorphic rocks?
Minerals form in igneous rock as magma or lava cools. The minerals will form from the available chemicals in the magma as their crystallization temperature is reached. The sequence of mineral crystal formation from magma is described in the Bowen's Reaction Series. Metamorphic rock minerals are aligned, altered, or recrystallized from existing rock minerals due to the effects of heat and/or pressure.
How many densities can a given mineral have?
That depends on which form of the mineral. Some minerals have several forms, and the densities vary as the form does.
How can bowens reaction series determine the silica content in magma?
Higher silica contents will be in the igneous rocks that form with lower temps. Ones that form earlier in the series like olivine have lower percentages of silica.
What mineral tends to form last in Bowen's series?
Quartz.
What mineral tends to form first in bowen's series?
Olivine
How long does it take a mineral to form?
The chemical reaction that forms the product mineral happens almost instintaneously, but for great amounts of the mineral to form depends on how much of your reactants are present, the temperature, and many other factors. Some take a few seconds and some take millions of years to form a set mass of your mineral.

What is Bowen's reaction series about?
The purpose of Bowen's Reaction Series is to visually represent the conditions under which different igneous rocks form in an organized way that is easy for the viewer to understand. Bowen's Reaction Series is important to geologists because it helps them understand the order in which specific minerals were created.
What is the first minerals tends to form by Bowen's Series?
Bowens' Reaction Series measures the melting points of various silicate minerals, with the ones with highest melting points at the top. So as a completely moltenmagma containing all these minerals cools down, the first to crystallise are:ABOUT 1400 CELSIUSOlivinePyroxene (e.g. augite)Amphibole (e.g. hornblende)Biotite micaOrthoclase feldsparMuscovite micaSilica (e.g. quartz).ABOUT 800 CELSIUSNotice I've deliberately left out plagioclase feldspar because plagioclases of different composition crystallise out at different temperatures. Calcium-rich plagioclase crystallises out at about the same temperature as olivine (mineral 1), but sodium-rich plagioclase crystallises out about the same temperature as biotite mica (mineral 4). All plagioclase crystallises out at a higher temperature than orthoclase (mineral 5).So in answer to your question the first minerals to form as a magma cools are olivine and calcium-rich plagioclase feldspar, at around 1400 Celsius.

In bowens reaction series how do the tetrahedra in feldspar differ from those of silicates?
The simple answer is... Feldspar has a much higher complex and stable tetrahedral orientation in comparison to that of any other Silicate variation higher up on the reation series latter. Feldspar is one of the most stable variations in orientation of, what boils down to, silicate tetrahedra. Because Feldspar is technically a form of silicate tetrahedra orientation, I am assuming you are asking how the silicate tetrahedra orientations vary from its most simple (i.e. Olivine) to its mosts complex (i.e. quartz/FELDSPAR) forms. Esentially a Silicate Ion SiO4^-4 is the most basic building block of FELDSPAR. Knowing this, as you move from the top of Bowen's reaction series, we see a gradual stabilization of the various Silicate tetrahedral orientations. These orientations include (in order of stability/complexity): [TOP OF REACTION SERIES] Individual (Singular form) Silicate Tetrahedra (i.e. Olivine) Chain (Linear form) Silicate Tetrahedra (i.e. Pyroxine) Double Chain (Bilinear form) Silicate Tetrahedra (i.e. amphibole) Sheet Silicate Tetrahedra ('2-D' form) (i.e. Mica: Biotite or Muscovite) Framework Silicate Tetrahedra ('3-D' form) (i.e. FELDSPAR) [BOTTOM OF REACTION SERIES]
How do you determine a mineral’s streak?
The color of a mineral in powdered form is called the mineral's Streak
Why is water a mineral?
Water is not a mineral but water does form minerals.
The color of a mineral in powered form is called the mineral's?
Streak
