Slicing Up the Rocks. However, the people who study how these rocks form take it at least one step further and that is looking at rocks under the microscope.

Today, rocks can function as both a carbon source and sink. "Many people, including myself, considered metamorphic decarbonation to be a background process in the recycling of carbon," Penman said.

Researchers from Queensland's James Cook University found rare metamorphic diamonds in rocks along the Clarke River Fault, west of Paluma in the state's north, according to Science Advances Journal.

“In some places, there are metamorphic diamonds which you can’t even see with a microscope. You just see a reading in the rock which indicates they are in there,” the scientist said.

Microdiamonds in metamorphic rocks are important minerals because they form in ... 2023 — Scientists have discovered a new layer of partly molten rock under the Earth's crust that might ...

ONE of the world’s most difficult to find diamonds has been discovered in North Queensland.

These minerals are found in metamorphic rocks – rocks transformed by heat, pressure or both. One of the great joys in studying metamorphic rocks lies in microanalysis of their minerals.
