Physical properties
Varied: Hardness ranges from Graphite (1-2) to Diamond (10). Includes metallic, glassy, and dull lusters; isometric, hexagonal, and monoclinic crystal structures.
Formation & geological history
Formed through diverse geological processes including igneous crystallization, hydrothermal veins, sedimentary deposition (coal), and metamorphic transformation under extreme pressure.
Uses & applications
Essential for global industry: energy production, construction, electronics manufacturing, precious jewelry, and large-scale metal fabrication.
Geological facts
This set illustrates the breadth of earth resources. For instance, Diamonds are the hardest natural substance, while Coal is a combustible sedimentary rock formed from ancient plant matter.
Field identification & locations
Identify in the field using cleavage, streak tests, and hardness checks. Found globally in specific geological environments like cratons (Diamonds) or sedimentary basins (Coal).
