Lightning shocked quartz

Should some meteorite impact shocked quartz and glass be credited as formed by lightning discharges?

Dr Jay Melosh - Purdue University Distinguished Professor in the Department of Earth, Atmospheric, and Planetary Sciences - expands on the implications of a University of Pennsylvania 2017 paper. Melosh suggests that some meteorite glass found around the world might be the results of transformation by current, heat, shockwaves by the event.

Especially the Argentine Pampas where lots of meteorite glass sites could instead be electrochemical transmutation of elements?

Argentine Pampas lightning glass?

electrochemical geology lightning meteorite glassThis finding is important because there are now several reports of evidence for shock features in fulgurites. Gieré et al [Gieré et al., 2015] identified PDFs (Planar Deformation Features) in undoubted rock fulgurites from France, indicative of pressures up to about 10 GPa.

More enigmatic occurrences include the Edeowie glasses in Australia, which are attributed to an impact [Haines et al., 2001], but for which no evidence of a crater exists, and glasses from the Argentine Pampas [Schultz et al., 2004] that, if taken at face value, would imply impact rates vastly higher on the Pampas than anywhere else on Earth. Could these latter two reports really be reflecting lightning strikes, rather than meteorite impacts?

... Given the other peculiarities of fulgurites, this should not be impossible, but it will serve as a reminder that on Earth, meteorite impacts are among the most rare of geologic events. On our planet, lightning strikes more often than meteorites.

Thanks to Society for Interdisciplinary Studies news for bringing this to attention.

Argentine Pampas meteorite glassFulgurites have also been made artificially by strong electrical discharges and so their origin is not controversial.

They form when cloud-to-ground lightning strikes the Earth’s surface, generating air temperatures up to 100,000 K from currents that range upwards of 30 kA in cm-diameter channels with linear energy densities of a few MJ/m. Energies of this order can easily melt rocks on the surface, locally raising them to temperatures exceeding 2000 K.

The issue here, however, is not whether lightning can create high temperatures, but whether it can also generate pressures equal to those achieved in meteorite strikes.

Mineralogical transformations

electrochemical geology Lightning geology electric universe theory'Shocked' quartz comes in several varieties, depending upon the peak pressures involved. The lowest pressures that can produce features considered diagnostic of impact create “planar fractures” that form at pressures from 5 to 8 GPa [Stöffler and Langenhorst, 1994].

... 'Planar Deformation Features (PDFs)' form at higher pressures (7 to 30 GPa) and mineralogical transformations to high pressure phases Stishovite (12 to 15 GPa) and Coesite (> 30 GPa) occur at still higher pressures. Shock melting requires pressures in excess of about 50 GPa [Stöffler and Langenhorst, 1994].

Does ground to air lightning transform the ground?

Change the current, energy and can you scale the formations of fulgurites and glass?

Fulgurites, pipes, kimberlite diamond pipes, breccia pipes, seams, viens, metals. Glass, quartz and more precious gem stones.

planar deformation lamellae quartzFor our field site, we selected a lightning-struck basaltic outcrop at the Grimes Point archaeological site in Nevada. Grimes Point may hold the highest concentration of paleo-Indian petroglyphs in the United States. The selected outcrop is a boulder ~1 m in diameter and height and bears a petroglyph depicting a lightning strike on a vertical face. After subtracting the background magnetic field measured >20 cm from the outcrop, the residual magnetic field anomaly shows a clear channel of high intensity that traces the path of the current that flowed from the location of the lightning strike at the top of the outcrop to the ground.

Can Lightning Strikes Produce Shocked Quartz?

H J Melosh was involved in a previous 2012 paper on electromagnetic geology through lightning and possible lightning discharge shock metamorphism of quartz rock.

plasma Lightning geology electric universe theoryThe results illustrate that in most of the simulated cases maximum pressures outside the lightning channel do not exceed 10 GPa and shock heating alone appears insufficient to melt quartz. The fusing of quartz in “typical” fulgurite formation must instead be due to slower (but still rapid) heat transfer from the vaporized channel, which is neglected in our simple model.

However, in very high-energy, short-duration, narrow-channel lightning strikes maximum pressures can exceed 10 GPa in a narrow zone outside the lightning channel. These pressures may be sufficient to cause shock metamorphism of quartz .
Can Lightning Strikes Produce Shocked Quartz?

Mineralogical transformations shocked quartzUsing 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 fulgurite-producing lightning strike. This event must have generated a transient pressure pulse, whose magnitude, however, is uncertain at this stage.

Or other strikes as mentioned in what might be plasma inspired mythology, the old thunderbolts of the gods?

There are other theories that have been suggesting grander importance for the role of electric strikes in various scales in transforming the elements of our planets and all other planets geology.

With proposals in our recent past of inter planetary electrical discharges (through space plasma) which makes up over 95% of the observable universe.

Speeded up or very shortened chronology for different scenarios of Jumping Jupiters, Grand Tack Hypothesis and Nice models could mean these events happened in humans living memory. Most of our planets geology, even its surfaces, seem to be amazingly fresh looking, young.
