Research team is delving into history, exploring events that occurred hundreds of millions of years ago. A potential crater over 370 miles (600 kilometers) wide in central Australia may transform our knowledge of Earth’s geological past.
Researcher Daniel Connelly and Virginia Commonwealth University’s Arif Sikder, Ph.D., believe they have found evidence to support the existence of MAPCIS – the Massive Australian Precambrian-Cambrian Impact Structure – which is a nonconcentric complex crater that could provide new insights into the geological and biological evolution of our planet.
“Working on the MAPCIS project has been an incredible journey,” said Sikder, an associate professor in the Center for Environmental Studies, a unit of VCU Life Sciences. “The data we’ve gathered offers a unique glimpse into the forces that have shaped our planet, and I’m excited about the future research this discovery will inspire.”

This September, Connelly will make a presentation in Anaheim, California, at Connects 2024, the Geological Society of America’s annual meeting. In August, he presented at the 37th International Geological Congress 2024 in Busan, South Korea. According to researchers, the impact occurred at the end of the Ediacaran period, within the Neoproterozoic Era, which spans from 1 billion to 538.8 million years ago.
Geological Evidence of the Impact
Among the geological evidence they have uncovered to support the age, size, and location of the impact are massive deposits of pseudotachylite breccia, or melt rock, near the crater center. The researchers found shocked minerals, including lonsdaleite, or shocked diamond, in the deposits, along with impact level amounts of iridium.
“The discovery of MAPCIS is a testament to the power of collaborative research,” Connelly said. “Our findings not only highlight the significance of this impact structure but also open new avenues for understanding Earth’s geological past.”

Seeing it all cleaned up like that, it looks like a car my mother had.
My Mother the car, not exactly a hit :) My Mother the Car is an American fantasy comedy that aired for a single season on NBC between September 14, 1965, and April 5, 1966.
Not sure I can do that, good sir. Seems like it might just easily another orifice, however, located as it is down there.

Yours doesn’t have a “Trump” sticker.
It’s obvious.
Gaze at your naval. Look at the picture.
Assuming that you’re an innie.
If you’re an outie you might need to gaze at someone elses.
And if you’re still not convinced, gaze at your other orifices and see which one you think matches best.
Because they have Good aim
That one in AZ is special, though. You see how close it came to the gift shop?
A taxpayer grant?
The military is even worse. I once attended a high level classified briefing at Patterson AFB. Lots of generals and other senior officers. I could not understand half of what they were talking about because of all the acronym. Might as well been in a foreign language.
During one of the breaks I mentioned it to one of the junior officers. A short time later he handed me a two page cheat sheet with all the acronyms explained so I could follow the briefing.
I guess I was not the first to mention the problem.
Like most things, why is this an either/or proposition?
An asteroid big enough to blast out a 370 mile-wide crater? Man, our distant ancestors had all the luck. They didn’t have to try to vote out their liberals.
You mean continental drift theories?
Well, it either initially happened relatively quickly, or has been happening very slowly for millennia.
Can't really be both ("freeze, put your hands up").
I’ll have to get back to you.
Good question...
Daily drive and a fast Sunday driver sweet.(drag races)

I saw the same thing in the private sector in commercial mortgage banking.
All newbies were handed a glossary of terms as part of the on-boarding process.
It ran about ten pages single spaced—hundreds of terms and acronyms.
Every sector speaks its own language in this highly specialized world.
