Teaching Students About Economic Geology

Economic geology is a sub-discipline of geology that deals with the distribution and use of Earth’s natural resources, such as minerals, rocks, and energy resources like oil, coal, and natural gas. It plays a crucial role in society as it provides valuable insights into the sustainable use of these resources to support the global economy. Educating students about this field instills an understanding of the importance of natural resource management and responsible consumption. This article will guide educators on how to teach students about economic geology effectively.

1. Start with the Basics

Introduce your students to the fundamentals of geology before delving into economic geology. Teach them about rocks, minerals, geological formations, and various types of geological processes such as sedimentation, glaciation, and metamorphism. These basic concepts will create a foundation for understanding complex topics related to resource extraction and their associated challenges.

2. Explore Different Types of Resources

Once students have grasped foundational geological concepts, start discussing the various types of resources essential to modern society. Examples include:

– Metallic resources: Iron, copper, gold
– Non-metallic resources: Salt, gypsum, silica sand
– Energy resources: Coal, oil, natural gas
– Water resources: Groundwater, surface water

Explain how these resources are formed over time through various geological processes and their relevance for human development.

3. Discuss Exploration Techniques

Explain how scientific methods are used to locate valuable resources that exist beneath Earth’s surface. Discuss techniques such as remote sensing (e.g., aerial photography and satellite imagery), seismic surveying (using sonic waves), aerial and ground magnetic surveys (detecting changes in Earth’s magnetic field), and core drilling (sampling rocks).

4. Resource Extraction Methods

Discuss the processes involved in extracting different resources from the Earth’s crust, including mining (open-pit and underground), drilling (for oil and gas), and quarrying (for stone and other building materials). Explain the benefits, drawbacks, and environmental impacts of these extraction methods.

5. Emphasize Environmental Considerations

Highlight the need for sustainable resource extraction to minimize adverse environmental impacts. Incorporate discussions about land degradation, waste disposal, water pollution, and other environmental problems related to resource extraction. Encourage students to think critically about how we can mitigate these issues through sustainable practices, such as recycling materials and adopting alternative sources of energy.

6. Case Studies

Incorporating specific examples and case studies from different parts of the world can help students develop a deeper understanding of how economic geology impacts various communities. Discuss historical and current examples of mining projects in different regions, their contribution to local economies, as well as their environmental and social impacts.

7. Encourage Critical Thinking

Help students analyze complex topics related to resource management by presenting them with real-world challenges faced by policymakers, industry professionals, and local communities. Encourage class discussions, debates, and written assignments that require students to consider perspectives from different stakeholders involved in natural resource management.


Integrating the study of economic geology into your curriculum not only provides students with a robust understanding of the Earth’s resources but also equips them with the knowledge to make informed decisions about the responsible use of these resources in their daily lives. By utilizing the tips discussed in this article, educators can engage students effectively in learning about this fascinating subject while fostering critical thinking skills vital for future scientific endeavors.
