What is the difference between green and blue kyanite?
The difference between the green and blue kyanite is their colors.
Is kyanite a sedimentary rock?
No. Kyanite is a mineral.
What are two examples of index minerals?
kyanite and sillimanite
What is kyanite and how is it formed?
temperatures above 1100 °C kyanite decomposes into mullite and vitreous silica via the following reaction: 3(Al2O3·SiO2) → 3Al2O3·2SiO2 + SiO2
Are andalusite sillimanite and kyanite sedimentary rocks?
NO. These are purely metamorphic minerals and not rocks at all!They are found in metamorphic rocks of different environments and are pure alumino silicate phases.
What is the difference between green and blue kyanite?
The difference between the green and blue kyanite is their colors.
Is kyanite a sedimentary rock?
No. Kyanite is a mineral.
How do you differentiate sapphire and kyanite?
Kyanite is too soft for everyday and more importantly doesn't sparkle very well. On the other hand, Sapphire is lovely and clear whilst kyanite at first glance looks clear but on looking in detail in light, it will found to be flat. The colour of a Kyanite can be that of an expensive sapphire but put next to each other, there will be no comparison in clarity or depth.
What is the density of kyanite?
Kyanite has an average density of 3.61.
Is kyanite silicate or non silicate?
Kyanite is a silicate. Sometimes called an aluminiosilicate. It has a chmical composition of Al2SiO5 It has variable colors when found in nature- this is due to contamination with small amounts of metals ions such as iron, titanium.
Is kyanite magnetic?
no
Is Kyanite is an index mineral of a low grade metamorphism?
No, kyanite is an indicator of high pressure metamorphism.
From which language does the word Kyanite come from?
The word kyanite is derived from the Greek language. The Greek word it comes from is kuanos which means a deep blue color which is likely because of the lovely blue color of Kyanite.
What are examples of index mineral?
kyanite and sillimanite
Mineral starting with k?
Potassium
What is kyanite mostly used for?
Kyanite and its two related minerals, andalusite and sillimanite, are used primarily in the glass-making, metallurgy, refractory, and ceramic industries.
What are two examples of index minerals?
kyanite and sillimanite
