Lonsdaleite Diamonds formed by high energy event?

lonsdaleite diamonds canyon diablo meteor craterA recent study has concluded that the infamous impact mineral lonsdaleite or sort of diamond is a mineral changed by what science terms as a meteor impact.

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

Scientists have argued for half a century about the existence of a form of diamond called lonsdaleite, which is associated with impacts by meteorites and asteroids. A group of scientists based mostly at Arizona State University now show that what has been called lonsdaleite is in fact a structurally disordered form of ordinary diamond.

lonsdaleite diamonds fulgurites desert glassAre 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 diamonds formation mystery

lonsdaleite diamonds meteor impactLonsdaleite 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?

The intensity of heat and pressure decreased with distance from the impact point. At a distance of about 12 kilometers out from the point of impact, the conditions were probably still too severe for the formation and survival of diamonds.
The diamonds found today were probably formed in a thin zone of rock located about 12 to 13 kilometers out from the point of impact. This created a shell of diamond-bearing rock about 1 to 2 kilometers thick in the shape of a hemisphere around the point of impact. In this zone flakes of graphite in the Archean graphite-garnet gneiss were instantly converted into diamond.

Could Lonsdaleite diamonds have been the result of high energy electromagnetic forces during a discharge event? Could it be just the local minerals being transformed? Could all diamonds and minerals be formed in this way?

Natural forming Lonsdaleite diamonds?

It is also naturally occurring 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.
