Quick Answer: This coal rock specimen set shows successive stages of coalification, from peat and lignite through to bituminous coal, for teaching how fossil fuels form from organic sediment over geological time.
Product Description
The Coal Rocks Fossil Energies set provides real specimens illustrating the coalification process, the gradual transformation of plant matter into coal under heat and pressure over millions of years. By comparing specimens at different stages, students can observe visible differences in colour, texture, and density that correspond to increasing carbon content and energy value.
The set supports coursework on sedimentary and organic geology, the formation of fossil fuels, and the broader carbon cycle, and works well alongside lessons on stratigraphy since coal seams form within layered sedimentary sequences.
Specimen Details
| Detail | Description |
|---|---|
| Product Type | Coal specimen set illustrating coalification stages |
| Subject Focus | Fossil fuel formation, organic sedimentary geology |
| Recommended Level | Secondary and introductory university geology/earth science |
| Storage | Dry, labelled tray; some specimens are friable and should be separated |
Applications
- Teaching the coalification sequence from organic matter to coal
- Fossil fuel formation and organic sedimentary geology lessons
- Comparative specimen study of coal rank and carbon content
- Supporting stratigraphy and carbon cycle coursework
Care & Handling
Lower-rank specimens such as peat or lignite tend to be softer and more friable than higher-rank coal, so handle them gently and keep each stage in a separate labelled compartment. Store the set in a dry area, since moisture can accelerate deterioration of lower-rank organic specimens.

Frequently Asked Questions
1. What does this set teach?
It teaches coalification, the process by which plant material is transformed into coal over geological time through the combined effects of heat and pressure.
2. What stages of coal formation does the set include?
It includes specimens representing different points along the coalification sequence, allowing students to compare texture, colour, and density as coal rank increases.
3. Why do the specimens vary in hardness?
Lower-rank specimens such as peat or lignite are less compacted and more friable, while higher-rank coal is denser and harder, reflecting the degree of transformation.
4. Is this set suitable for stratigraphy lessons?
Yes, since coal seams form within layered sedimentary sequences, the set pairs well with lessons on stratigraphy and sedimentary basin formation.
5. What level of course is this set suited to?
It suits secondary school and introductory university geology or earth science courses covering fossil fuel formation and organic sedimentary geology.
6. How should the specimens be stored?
Store them dry, in a labelled tray with each stage kept separate, since lower-rank specimens are more fragile and can deteriorate with moisture exposure.
