Authentic Exogenic Fulgurite Whispy Letter " J"
Authentic Exogenic Fulgurite Whispy Letter "J"
The full story is written up in Rocks & Minerals, Sep/Oct 2004, Vol. 79, No. 5, pp334-340, and it is authentic! Most of this material is in private collections or museums.
When lightning strikes the earth's surface and melts the materials it contacts, the remains are collectively known as fulgurites. Their classification has generally been limited to forms that form below the surface of the ground as soil, rock, sand, or clay fulgurites. In 2004 there was the first documentation of "exogenic fulgurites," those formed from lightning striking vegetation and causing the heated, liquefied remains to be ejected into the atmosphere. During their descent, while cooling, these exogenic fulgurites mimic the shape of the original material.
So why aren't these more common? Although "a lightning strike" is commonly used to describe all lightning only about 25% of all lightning events worldwide are cloud to ground. The other 75% is cloud to cloud or inter-cloud.
Perhaps most exogenic fulgurites, when found, can also be misinterpreted as anomalous material and discarded. This might be why there is not much talk about them or more "finds," as people simply don't recognize what they are.
The odd contortions and shapes of the specimens make them an interesting addition to a serious collection of geological oddities and a real scientific contribution to understanding lightning's action on above ground materials.
This is a fantastic, very detailed and unique specimen.
