Economic Significance of Igneous Rocks
1)Since magma is the chief source of metal ores, many of them are associated with igneous rocks.
2)The minerals of great economic value found in igneous rocks are magnetic iron, nickel, copper, lead, zinc, chromite, manganese, gold, diamond and platinum.
3)Amygdales are almond-shaped bubbles formed in basalt due to escape of gases and are filled with minerals.
4)The old rocks of the great Indian peninsula are rich in these crystallised minerals or metals.
5)Many igneous rocks like granite are used as building material as they come in beautiful shades.
Economic Significance of Sedimentary Rocks
1)Sedimentary rocks are not as rich in minerals of economic value as the igneous rocks.
2)But important minerals such as hematite iron ore, phosphates, building stones, coals, petroleum and material used in cement industry are found.
3)The decay of tiny marine organisms yields petroleum. Petroleum occurs in suitable structures only.
4)Important minerals like bauxite, manganese, tin are derived from other rocks but are found in gravels and sands carried by water. Sedimentary rocks also yield some of the richest soils.

In this question, we are asked to talk about the economic significance of rocks.
- They serve as vast mineral storage facilities. They are where valuable metals such as gold, silver, platinum, etc. are found.
- They are a source of mineral fuel. They offer several stone varieties.
- Soil's primary constituent is rock.
- Rocks can also be found as ores, which are a source of several metals.
- Minerals like phosphates and nitrates are found in rocks.
- Rock weathering is the source of soil. Rocks are the source of almost all building materials used for constructing flooring, buildings, and paving roads.
- They provide precious metals including gold, platinum, and other metals.
- Minerals and rocks are everywhere around us. They are a part of daily life and aid in the development of new technology.
- We use rocks and minerals for things like construction, cosmetics, transportation, infrastructure, and appliances.
- People need to eat minerals every day to be healthy and build their bodies.
