Introduction To Minerals and Energy Resources
1. Introduction to Minerals/What is a mineral?:
- Minerals are homogeneous, naturally occurring substances with a definable internal structure.
- Found in varied forms:
a. Hardest: Diamond.
b. Softest: Talc. - Minerals are the building blocks of rocks, which can be single-mineral (e.g., limestone) or multi-mineral compositions.
2. Importance of Minerals:
- Daily Life Usage:
a. Minerals are essential for everything from a pin to a ship.
b. Used in construction (buildings, roads, railway tracks) and manufacturing (cars, buses, machinery).
c. Power sources like fuels are derived from the earth’s minerals. - Human Life Dependency:
a. Life processes depend on minerals; they enable the utilization of other nutrients.
b. Only 0.3% of nutrient intake comes from minerals critical for survival. - Cultural Significance: Minerals have been used historically for livelihood, decoration, ceremonies, and religious rites.
3. Properties of Minerals:
- Minerals differ due to physical and chemical conditions during formation.
- Properties used for classification:
a. Colour, hardness, crystal form, lustre, and density. - Minerals vary in abundance: Over 2000 minerals identified, but only a few are common in most rocks.
4. Geological Perspective:
- Formation of Minerals: A combination of elements forms specific minerals under certain conditions.
- Minerals in Rocks:
a. Rocks are combinations of minerals in varying proportions.
b. Example: Limestone contains a single mineral; others are multi-mineral.
5. Role of Geographers and Geologists:
- Geographers: Study minerals to understand landforms, distribution, and associated economic activities.
- Geologists: Focus on the formation, age, physical and chemical composition of minerals.
6. Applications and Daily Observations:
- Transportation Systems:
a. Buses, trains, and aeroplanes are made of minerals and run on mineral-derived fuels. - Toothpaste Ingredients:
a. Cleaning agents: Silica, limestone, aluminium oxide, phosphate minerals.
b. Fluoride: From fluorite to prevent cavities.
c. Whitening: Titanium oxide from rutile, ilmenite, anatase.
d. Sparkle: From mica. - Light Bulb: Investigate the variety of minerals involved in its creation.
- Plastics in Toothbrush: Derived from petroleum, showcasing the role of minerals in modern life.
7. Classification of Minerals:
- Minerals can be classified based on their geological formation, properties, and commercial uses.
8. Case Study from Text:
- Haban’s visit to Guwahati highlights the role of minerals in creating transportation systems (buses and trains made of iron, and aluminium).
- Minerals are indispensable in socio-economic activities, supporting daily life and industrial growth.
