Study Notes
- Minerals and energy resources are essential to daily life and economic development.
Minerals and Their Importance
- The Earth's crust consists of various minerals embedded in rocks.
- Minerals are extracted from these rocks after refinement.
- Minerals are indispensable, used in everything from pins to buildings.
- They're components of infrastructure, vehicles, and even food.
- Historically, minerals have been used for livelihood, decoration, and rituals.
- Toothpaste contains minerals like silica, limestone, and aluminum oxide for cleaning.
- Fluoride in toothpaste comes from fluorite and reduces cavities.
- Titanium oxide makes toothpaste white.
- Mica provides the sparkle
- Life processes require minerals, though they make up only 0.3% of nutrient intake.
- Without minerals, the body cannot utilize the other 99.7% of foodstuffs.
Defining and Classifying Minerals
- Geologists define a mineral as a homogenous, naturally occurring substance with a definable internal structure.
- Minerals vary widely, from diamond to talc, due to different formation conditions.
- Geologists classify minerals based on their properties like color, hardness, and density.
- Geographers study minerals to understand landforms and economic activities.
- Geologists study mineral formation, age, and composition.
Occurrence of Minerals
- Minerals are typically found in ores, which are mixtures of minerals and other elements.
- A mineral's content in an ore must be sufficiently concentrated for viable extraction.
- The formation type determines the ease and cost of mining.
Formation Types
- In igneous and metamorphic rocks, minerals occur in cracks, crevices, faults, or joints as veins and lodes.
- They form as liquid/molten and gaseous minerals cool and solidify while rising to the surface.
- Sedimentary rocks contain minerals in beds or layers, formed by deposition and accumulation.
- Coal and iron ore are concentrated through heat and pressure in horizontal strata.
- Evaporation in arid regions leads to the formation of gypsum, potash salt, and sodium salt.
- Decomposition of surface rocks and removal of soluble constituents leaves a residual mass of weathered material containing ores, e.g., bauxite.
Classifying Minerals
- Minerals are classified as Metallic, Non-Metallic, and Energy Minerals.
- Metallic minerals are further broken down into Ferrous, Non-Ferrous, and Precious.
