fulgurite
Definition
Noun: - A geological formation: "Fulgurite" refers to a hollow, glassy tube or crust formed when lightning strikes sandy soil or rock, fusing the silica into a vitrified (glass-like) structure. These formations are often tubular or branching, resembling roots or veins, and are found in deserts, beaches, or other sandy areas.
Usage Examples
- (A natural glass tube formed by lightning.)
- (Geological formations used for research.)
Advanced Usage
- "Fulgurite as a fossilized lightning strike": In geological contexts, fulgurites are sometimes described as "fossilized lightning" because they preserve the shape and energy of a lightning discharge.
- The fulgurite found in the desert was over a meter long, a rare and well-preserved example of a lightning strike. (A large, intact fulgurite.)
