This rock was found back in 2011, but since then it has not been possible to analyze its properties in detail. Now they
During the analysis of the properties, scientists found in itfour additional grains of zircon, a hard mineral known as a substitute for diamonds. With the help of it, it was possible to restore the history of temperatures and find out that it was heated to 2 370 ℃. The researchers worked in the impact crater of Lake Mistastin (Canada).
The article also notes that for the first time on thisThe site found reidites - minerals formed when zircon is subjected to high pressure and temperature. The team found three raidites still preserved in the zircon grains, and evidence that two more were once present but crystallized when temperatures exceeded 1,200℃, after which the raidite ceased to be stable.
This mineral allows researchers to betterdetermine pressure conditions. So they realized that the peak pressure was between 30 and 40 gigapascals. It is these pressure conditions that were created when a meteorite hit the surface. Certain minerals that are highly compressed by this event leave behind structures that can be studied.
The research team plans to extend this work to other impact craters on Earth.
