  Minerals play an important role in forming rocks and shaping Earths surface When humans began making tools out of iron great progress was made in advancing the world through industries Below is a timeline showing how the value and uses of minerals have changed over time . A homogenous, naturally occurring substance with definable internal structure is called mineral. .. Mode of occurrence of minerals:. (1) In igneous and metamorphic rocks: The smaller occurrences are called veins and the larger occurrences are called lodes. They are usually formed when minerals in liquid/molten and gaseous forms are forced upwards through cavities towards the earth’s surface. Examples: tin, copper, zinc, lead, etc..
