Was this special granite rock, which is much less dense than standard granites, originally much deeper in the Earth’s crust and forced up to the surface by a meteor impact or could there be other possible processes that may explain how it was formed?
Unexpectedly, the researchers noted that rocks from peak rings “got fundamentally altered by their journey upward during the impact,” Gulick said. “They end up lower in density by a lot, with their porosity increasing from 1 to 2 percent to 10 percent.”
These changes may have proven critical for the evolution of life on Earth, and perhaps on other planets, Gulick said. “When you get rocks with 10 percent more pore space, microbial life living below the surface may find new habitats on the surface,” he said. “Our next area of research involves looking at whether ecosystems can get started by craters.”

In April and May 2016, an international team of scientists undertook an offshore expedition and drilled into part of the Chicxulub impact crater. Their mission was to retrieve samples from the rocky inner ridges of the crater — known as the ‘peak ring’ — drilling 506 to 1335 metres below the modern day sea floor to understand more about the ancient cataclysmic event.
Now, the researchers have carried out the first analysis of the core samples. They found that the impact millions of years ago deformed the peak ring rocks in such a way that it made them more porous, and less dense, than any models had previously predicted.

Chicxulub crater granite formation processes
- It is crater impact metamorphic granite rock brought up from the Earths crust and transformed during this process
- Transmutation by another process involving high levels of energy/forces that triggered metamorphism of the local rock and converted it in situ
- The formation of the geological feature, known as a crater, also changed or had to create the special low density granites (EU geology, shockwave geology, cymatics geology, electromagnetic geometry etc)
- Various rock types, strata, chemicals, combinations of these were part of the natural design of the formation to help create life including disaster species
