What scientists work in mining?
Mineralogists work in mining. Their object of study is called Mineralogy. There are some classes of mineralogy. Chemical, biomineralogy, Optical, / Physical, which includes crystal structure, crystal habit, twinning, cleavage, luster, diaphaneity, color, streak, hardness, specific gravity. / Chemical mineralogy focuses on the chemical composition of minerals in order to identify, classify and categorize them, as well as a mean to find beneficial uses from them. Biomineralogy is a cross-over field between mineralogy, paleontology and biology. Optical mineralogy is a specific focus of mineralogy that applies sources of light as a means to identify and classify minerals.
What does it mean to say that a mineral has a definite chemical composition?
In mineralogy, definite chemical composition refers to a characteristic that a substance must possess to meet the definition of a mineral. It is the narrow parameter of chemical compositions that a substance must have to be described as a particular mineral separate from other minerals.
What is an example of a polymorph?
A polymorph is defined as same composition, different chemical structures. Quartz, cristobalite, and tridymite are examples of polymorph because they are three different minerals with the same chemical composition. Graphite and diamond are also good examples of polymorphism. They both contain carbon atoms, but they have extremely different properties because of the condition in which they formed. Diamond forms where extreme pressures and temperatures produce its compact structure. On the other hand, graphite forms under comparatively low pressures and it has weekly bonded carbon sheets that create its greasy feel. The difference in conditions makes diamond much harder than graphite and graphite much more useful as a lubricant.
Why is the chemical composition of a mineral important?
it means a naturally-occaring, inorganic solid that has a crystal structure and a definite chemical composition
What is the Chemical Composition of Specularite?
Fe2O3
What forms when high temperatures and pressures combine to alter mineralogy or chemical composition of a rock without melting it?

What is a defintite chemical composition?
In mineralogy, definite chemical composition refers to a characteristic that a substance must possess to meet the definition of a mineral. It is the narrow parameter of chemical compositions that a substance must have to be described as a particular mineral separate from other minerals.
What are related to chemistry?
Chemistry is the study of chemical composition of materials, of chemical reactions, of the structure of molecules, of molecules synthesis, etc. Chemistry is close to physics, mineralogy, biology.

Is a liquid at normal temperatures and pressures a physical or chemical change?
This liquid is only a liquid, not a change.
Why do different liquids boil at different temperatures?
These liquids have different chemical composition and structure.

What is the lower mantle made of?
It is made up of a magnesium silicate mineral called Perovskite. For more information on the chemical composition and mineralogy of the mantle, please see the related question.
What caused a change in the chemical composition of coastal waters during Hurricane Floyd?
The difference would have been the water temperatures.
Is breaking a toothpick a physical or chemical change?
Yes; at very low temperatures toothpastes can be frozen.
