Mineral from destroyed planet's core? + History of lost continent uncovered

Could This New Mineral Be From a Destroyed Planet’s Core?

EXCERPT: . . . Exactly how the mineral formed is speculative. Geoffrey Bonning, a planetary scientist at the Australian National University not involved in the study, tells Mannix that it’s likely that the meteorite comes from the interior of a planet that formed in our early solar system. As dust and rock coalesced into a planet, the core heated up producing minerals like edscottite. At some point, that planet likely bashed into another planet, a moon or massive asteroid that smashed it to bits. Those chunks, including the rock that produced the Wedderburn Meteorite, then ended up in the asteroid belt between Jupiter and Mars where it circled for billions of years before another collision sent it toward Australia.

Geologists uncover history of lost continent buried beneath Europe

EXCERPT: Forget the legendary lost continent of Atlantis. Geologists have reconstructed, time slice by time slice, a nearly quarter-of-a-billion-year-long history of a vanished landmass that now lies submerged, not beneath an ocean somewhere, but largely below southern Europe. [...] Greater Adria had a violent, complicated history, notes Douwe van Hinsbergen, a geologist at Utrecht University in the Netherlands.

It became a separate entity when it broke away from the southern supercontinent of Gondwana (which comprised what is today Africa, South America, Australia, Antarctica, the Indian subcontinent, and the Arabian Peninsula) about 240 million years ago and started to move northward, scientists believe. About 140 million years ago, it was a Greenland-size landmass, largely submerged in a tropical sea, where sediments collected and slowly turned into rock. Then, as it collided with what is now Europe between 100 million and 120 million years ago, it shattered into pieces and was shoved beneath that continent. Only a fraction of Greater Adria’s rocks, scraped off in the collision, remained on Earth’s surface for geologists to discover.

Another complication is that Greater Adria’s rocks are dispersed across more than 30 countries, in a swath from Spain to Iran. [...] In the new study, van Hinsbergen and his colleagues spent more than 10 years collecting information about the ages of rock samples thought to be from Greater Adria...
