Lonsdaleite Diamonds Fulgurites Desert Glass

Lonsdaleite also called hexagonal diamond in reference to the crystal structure, is an allotrope of carbon with a hexagonal lattice.

In nature, it forms when meteorites containing graphite strike the Earth. The great heat and stress of the impact transforms the graphite into diamond, but retains graphite's hexagonal crystal lattice.

Lonsdaleite diamonds has been found around the Tunguska Event, Canyon Diablo (Barringer/Meteor Crater in Arizona), Popigai crater and other 'impact' craters or areas.



Are diamonds and minerals formed by mega electrical discharges or events in and on the earths surface?

Comet/meteor impacts in deserts are said to create desert glass. Lightning strikes (plasma) can create fulgurites.

Could desert glass be due to a plasma discharge? Could a bigger electromagnetic discharge transform/deform minerals into diamonds or diamonds that are already there into Lonsdaleite diamonds?

Lonsdaleite is basically a normal diamond but geology theory suggests it is a mineral changed into a Lonsdaleite diamond due to shock/energy/pressure, most likely from a meteor impact.

Geology theory says that diamonds are formed deep underground due to the intense heat/energy/pressure needed to transform rock into diamonds.



Then they just happen to rise and use to be found glittering on the surface or now just below the surface or on the seabed floor. Could it be the earths material/minerals transformed by a shock event?

Lonsdaleite naturally occurs in non-bolide diamond placer deposits in the Sakha Republic. Material with d-spacings consistent with Lonsdaleite has been found in sediments with highly uncertain dates at Lake Cuitzeo, in the state of Guanajuato, Mexico, by proponents of the controversial Younger Dryas impact hypothesis.

Its presence in local peat deposits is claimed as evidence for the Tunguska event being caused by a meteor rather than by a cometary fragment.

Lonsdaleite is simulated to be 58% harder than diamond on the <100> face and to resist indentation pressures of 152 GPa, whereas diamond would break at 97 GPa. This is yet exceeded by IIa diamond's <111> tip hardness of 162 GPa.
