What mineral tends to form first in bowen's series?
Olivine
Is amethyst an rock or mineral?
Amethyst is a mineral, a form of quartz.
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 is argon used in its Natural mineral?
In its natural form, argon is a gas, not a mineral!
What is the mineral group for amethyst?
Amethyst, a form of quartz, is in the silicate mineral group.
What mineral tends to form first in bowen's series?
Olivine
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 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.
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?

The color of a mineral in powered form is called the mineral's?
Streak
Is amethyst an rock or mineral?

What does sodium form?
Sodium tends to form ionic compounds.
What minerals form?
Sapphire is a form of the mineral corundum.
2 processes involving solutions that form a mineral?
Two processes involving solutions that form a mineral:- precipitation- dissolution
How do you think the hardness and density of a mineral that form through metamorphism would compare to a mineral that form through evaporation?
By knowledge
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.
