What are minerals? On what basis can the minerals be identified? Give examples
Answers
Answer:
A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes. Examples include quartz, feldspar minerals, calcite, sulfur and the clay minerals such as kaolinite and smectite
Answer:
A mineral is, broadly speaking, a solid chemical compound that occurs naturally in pure form. ... In geology and mineralogy, the term "mineral" is usually reserved for mineral species: crystalline compounds with a fairly well-defined chemical composition and a specific crystal structure.
Minerals are classified on the basis of their chemical composition, which is expressed in their physical properties. This module, the second in a series on minerals, describes the physical properties that are commonly used to identify minerals. These include color, crystal form, hardness, density, luster, and cleavage.
