fulgorology

Fulgorology is the study of fulgurites, which are natural glass or glassy tubes formed when lightning strikes sand or soil. These fascinating geological formations are created by the intense heat and rapid melting of silica-rich materials, followed by quick cooling. The process essentially fuses the sand grains together, creating a hollow or solid structure that often resembles the branching path of the lightning strike itself.

Fulgurites can vary greatly in size, shape, and color depending on the composition of the ground struck and the characteristics of the lightning. They are typically found in sandy deserts, beaches, and areas with loose, unconsolidated soil. The color can range from white and tan to black and green, often reflecting the presence of impurities within the sand.

The scientific study of fulgurites, fulgorology, seeks to understand the electrical and thermal processes involved in their formation. By examining their morphology and composition, researchers can glean insights into the behavior of lightning, the properties of the materials they are formed from, and the geological conditions present at the time of the strike. Fulgurites are rare and often fragile, making them prized specimens for both scientific research and collectors.
