Superimpose the maps showing distribution of iron ore, manganese

Superimpose the maps showing distribution of iron ore, manganese, coal and iron and steel industry. Do you see ‘ any correlation? Why?

The iron and steel industries are located in the same regions of India where the iron ore, coal and manganese mines are located. As coal and manganese are required as inputs to the iron and steel industry, their availability in the same region saves on transportation costs as well as on ease of availability. So, it is profitable to locate these industries in the regions where these minerals are available.
