Each known mineral has a specific chemical composition.
The color of a mineral sample is determined by its chemical composition
the composition of luster is limstone
The chemical composition of a mineral is important because it helps identify the mineral and provides information on its physical and chemical properties. Understanding the composition can help determine how the mineral formed, where it is found, and how it can be used in various applications.
The Precambrian is a geological age, not a mineral.
It is a mineral or a number of minerals which are part of the composition of rock.
