It tells us if the rock is Mafic (dark) composed mostly of magnesium and ferrum Or Felsic, (light) composed mostly of silicates such as quartz and feldspbar, or intermediate, a mixture of the two.

Why are some igneous rock dark and other light?
The color will depend on the mineral composition of the magma.
What igneous rocks have a mineral composition between that of granitic and basaltic rocks?
Andesitic igneous rock.
How are basalt and granite different in their Orgin texture and mineral composition and how are they similar?
Both rocks are igneous rock but basalt is an aphanitic igneous rock while granite is a common type of felsic intrusive igneous rock.
How can the mineral quartz be an igneous rock?
Quartz is a rock-forming mineral--and can be found in all three rock types. There is no igneous rock formation that is exclusively composed of the mineral quartz.
Would mineral content classify an igneous rock?
No -- it's a type of rock, often a composite. Primay types are igneous (made by fire -- vulcanism), sedimentary (sea beds) and composite (a mixture of other types). In almost every case, all of these types are defined as how the substance at hand was created and in most cases they are not pure minerals.

Andesitic igneous rock.
How Does chemical composition affect the color of igneous rock?
The chemical composition of the rock affects the color of an igneous rockbecause some minerals like quartz change color becasue of t's own
What is the mineral composition of an intermediate igneous rock?
felsic and something else i do not remember the second one.
What characteristics determines the chemical composition of an igneous rock?
An igneous rock is any crystalline or glassy rock that forms from cooling of a magma. Color and texture help determine the chemical composition of the rock.
What determines the color of a igneous rock?
The composition of the magma or lava that it cools from.
How are basalt and granite different in their Orgin texture and mineral composition and how are they similar?
Both rocks are igneous rock but basalt is an aphanitic igneous rock while granite is a common type of felsic intrusive igneous rock.
What makes a igneous rock an igneous rock?
An igneous rock is formed through the solidification of molten material, either magma or lava, that cools and crystallizes. This process occurs below or on the Earth's surface. The mineral composition and texture of igneous rocks vary depending on factors such as the cooling rate and the composition of the molten material.
Is a igneous rock a mineral or rock?
You say it as ' Igneous ROCK ' and ask whether it is a rock..
What are two factors affect the type of igneous rock that is formed?
The mineral composition of the magma and the rate at which it cools determines what rock forms.
How can the mineral quartz be an igneous rock?
Quartz is a rock-forming mineral--and can be found in all three rock types. There is no igneous rock formation that is exclusively composed of the mineral quartz.
