Abstract Using transmission electron microscopy we show that planar deformation lamellae occur within quartz in the substrate of a rock fulgurite, i.e., a lightning-derived glass. These lamellae exist only in a narrow zone adjacent to the quartz/fulgurite boundary and are comparable to planar deformation features (“shock lamellae”) caused by hypervelocity impacts of extra-terrestrial objects. Our observations strongly suggest that the lamellae described here have been formed as a result of the…

The response of zircon to the extreme pressures and temperatures of a lightning strike.

Zircon dissociation to ZrO2 and SiO2 is a high-temperature, relatively low-pressure phenomenon, consistent with previous suggestions that lightning strikes involve extreme temperatures as well as pressures greater than those usually generated in Earth's crust but rarely > 10 GPa.

Lightning-induced high temperature and pressure microstructures in surface and subsurface fulgurites

This work broadens the near-surface environments in which rock fulgurite has been reported, and provides a detailed description of microstructures that can be compared to those formed during other types of extreme metamorphic events.

Mineralogical and compositional features of rock fulgurites: A record of lightning effects on granite

Abstract Fulgurites are a naturally occurring glass formed when sand, rock, or soil is struck by atmospheric electrical discharges (lightning). The aim of this paper is to provide insights into the

Impact geologists, beware!

Impact geologists have long assumed that shock metamorphic features, such as planar fractures and Planar Deformation Features (PDFs) in quartz are reliable indicators of an extraterrestrial impact. A

The forensics of fulgurite formation

Natural disasters such as forest fires can result in extensive and costly property damage. These events may be the result of a human error or system failure triggered by electrical discharge, and in

Electric Discharge-Not an Impact Caused Formation Of Upheaval Dome, Canyonlands National Park, Utah

This paper will provide an argument that Upheaval Dome, Canyonlands National Park, Utah, USA is a product of Electrical Discharge Machining (EDM). Currently two theories remain from a myriad of

Effects of Lightning on the Magnetic Properties of Volcanic Ash

High-current impulse experiments were performed on volcanic ash samples to determine the magnetic effects that may result from the occurrence of volcanic lightning during explosive eruptions, finding that the saturation (i.e., maximum possible) magnetization increased, and coercivity decreased.

The occurrence of iron silicides in a fulgurite: Implications for fulgurite genesis

Rapidly formed eutectic textures are observed in Fe silicides in a fulgurite from Michigan. The 14 cm-diameter fulgurite was formed in sandy glacial till in 2014 near Houghton Lake, Michigan.



Lightning Strike Fusion: Extreme Reduction and Metal-Silicate Liquid Immiscibility

Thermodynamic calculations indicate that temperatures in excess of 2000 K and reducing conditions approaching those of the SiO2-Si buffer were needed to form the coexisting metallic and silicate liquids.

Shock metamorphism of quartz in nature and experiment: II. Significance in geoscience*

— The occurrence of shock metamorphosed quartz is the most common petrographic criterion for the identification of terrestrial impact structures and lithologies. Its utility is due to its almost

Shock metamorphism of quartz in nature and experiment: I. Basic observation and theory*

Abstract— Quartz, as a ubiquitous mineral constituent of the Earth's crust, displays the greatest variety of well-defined residual shock effects among all rock-forming minerals. It represents an

Deformation and transformation in experimentally shock-loaded quartz

AbstractSingle crystals of quartz, shock-loaded along the a axis to pressures of 22 Gpa, 24 GPa, 26 GPa and 30 GPa were examined by high-voltage transmission electron microscopy (TEM), scanning

Shocked quartz in Sahara fulgurite

Comparative strain analyses were performed on quartz crystals within a Sahara fulgurite using neutron diffraction experiments. Besides, 3D-μXRCT (three-dimensional micro X-ray computed tomography)

Unusual features caused by lightning impact in West Greenland

Two lightning impacts are described from an area near the Inland Ice in West Greenland. The first lightning blasted an outcrop of metacherts. It subsequently split into two branches, which traversed

The fulgurite of Torre de Moncorvo (Portugal): description and analysis of the glass

The fulgurite of Torre de Moncorvo (Portugal) was formed by lightning striking a small electricity pylon; it consists morphologically of a central cylinder with radial ramifications several metres

An Unusual Lightning Flash at Kennedy Space Center

A lightning flash that struck the 150-meter weather tower at Kennedy Space Center was studied by several research groups using varioul techniques and found the charged regions neutralized by the three return strokes were located within a horizontal layer between heights of about 6 and 8 kilometers.
