G53 - Top Large Outstanding 22.8cm Fulgurite ("Petrified lightning") Collected in Algeria NWA Chondrite Polished Sections Here we present another relativelyFulgurites are natural tubes, clumps, or masses of sintered, vitrified, and or fused soil, sand, rock, organic debris and other sediments that can form when lightning discharges into ground. They can therefore be referred to as petrified lightning. They are classified as a variety of the mineraloid lechatelierite, although their absolute chemical composition is dependent on the physical and chemical properties of the usually granular crystalline
