Minerals :indespensable part of our lives
From a tiny Pintu a large building all are made from minerals the railway lines and the paving of the roads machinery to our made from minerals even the food we eat contain minerals in all the stages of development human beings have used minerals for their livelihood, decoration activity festivities our members comprisers of about 0.3% of our total intake of nutrients there so important that without them we should not be able to utilise the other 99.7% of the food step a stuffs

Minerals are found in nature in a variety of forms they are varied as they are found in different geological conditions.
Mode of occurrence
Minerals are usually found in yours the term Ore refers to combination of any mineral mixed with other elements minerals generally occurs in three forms these form against and metamorphic rocks igneous and metamorphic rocks minerals may occur in the cracks or joints of this rocks there formed when minerals in liquid oblique molten and gaseous forms are post upwards through hole towards the Earth surface a small occurrence are called when large currency are called loads in sedimentary rocks mineral sucker in beads or layers coal and some forms of iron ore cabin concentrated as the result of great heat and pressure Samundra Sar also from as a result of evaporation especially in arid regions residual mass it involve the decomposition of surface rocks and the removal of soluble constituent which leaves a residual mass of whether material containing or bauxite is formed in this way Alluvial deposits minerals in sands of Valley floor and the best base of Hills .
Theses deposits are called placer deposits.
e. g:- Gold, Silver etc
e) Ocean
Ocean water Kanchan vast quantities of minerals. example common salt bromine and manganese.
The ocean beds too are rich in manganese nodules.
