Welcome to the Second Gallery featuring
The Rebersburg Fulgurite

The Rebersburg Fulgurite was discovered near Rebersburg, Miles Township, Centre County, Pennsylvania in November 2015. The result of a massive lightning strike, the fulgurite formed what can only be described as an obsidian tree, wide at the base with a diminishing diameter farther from the initial strike, with bifurcating branches along the main trunk. This is the largest fulgurite ever discovered in Pennsylvania and it may well be one of the largest fulgurites discovered in the world. Some specimens on this page have extremely rare iron silicide nodules. Testing confirms the mineral Gupeiite which was previously known only to occur from extraterrestrial sources.

Geochemical analysis of iron silicide nodules and rock samples was performed at the West Chester University Center for Microanalysis and Imaging Research and Training (CMIRT) using an FEI Quanta 400 environmental scanning electron microscope and an Oxford Instruments Aztec X-ray Energy Dispersive Spectrometer (EDS).
Test results have been published by the Pennsylvania State Geological Survey in the Pennsylvania Geology Magazine Spring 2023 featured article,
The Rebersburg Fulgurite, available at the DCNR website.

All specimens of the Rebersburg Fulgurite have been sequentially numbered, labelled, photographed, and cataloged by Penn Minerals, including those gifted to Lehigh and West Chester University. Specimens offered here are guaranteed authentic, included in the catalog, and only available through Penn Minerals.
