The Electrical Origin of Kimberlite Pipes

Posted on --

Mined out kimberlite pipe, Kimberley Big Hole, Kimberley, South Africa.
Note the crater wall which is natural and formed by a “vortex” mechanism of unknown origin.
One of the more perplexing mysteries in geology is the mechanism behind kimberlite eruption at the Earth’s surface, because these eruptions have never been witnessed.
Historically, kimberlite eruptions tend to occur on the tectonically stable parts of the Earth’s landmasses, well away from the tectonically active zones where many active volcanoes are found, and from the stability of diamond-graphite pair we know they erupt catastrophically over a very short time, taking a matter of half a day from the initial melting in the mantle to eruption and solidification at the surface.
Another peculiarity these ancient volcanoes have lies in the close chronological association with global mass extinction events, where th--

I was quite amazed at how many kimberlite pipes there are even in Alberta but most arent diamondiferous.

My cook in the arctic was also the cook for Charlie Fipke who found the first diamond find in the NWT. He sounds like he was quite the character.
a short, absentminded Canadian geologist named Chuck Fipke. When he discovered diamonds in --, Northwest Territories, in 1991, he started the largest staking rush in North America since -- found gold in the Klondike a century earlier.
Fipke is a small man with a shaved head, a burnished tan, piercing blue eyes, and forearms like Popeye's. As a kid, his frantic start-stop mind made people think he was stupid. After getting his high school girlfriend pregnant, he agreed to marry her ... and then failed to show up for the wedding. (The couple eventually married after the baby was born.) He stutters and says "hey" in almost every sentence. He frequently loses his glasses and his keys, shows up late to appointments, and has a history of spending prodigious amounts of money in strip joints. His nicknames have included Captain Chaos and Stumpy.

Point Lake. Those were good days.

This sounds a bit like quacky science to me. Perhaps kimberlite pipes are found in geologically stable regions now, but that hardly means that they were geologically stable when the pipes were being formed. In fact is there any part of the world that has experienced geologic stability over the last few billion years?

Depends what your definition of stable is.

Another possibility is that these kimberlite pipes are what is today's hot spots from the heated interior. Not necessarily a Birkeland current strike but the release of super heated core energy again synchronizing with a reoccurring cosmic event.
