Solarium is a chemical found in most sun-dried sand, but it has also been found in other sandstones and has been found on rocks and in the earth’s crust.

Now, researchers from the University of Queensland say that its presence in sandstone is not due to an organic compound, but rather is due to a chemical reaction between the particles.

“This is the first study to show that this is a simple, natural reaction that occurs in the sand and not some kind of organic compound,” Dr Matthew MacGregor, one of the study’s authors from the Department of Geology and Geophysics, said.

“Our study shows that the chemical reaction that produces this material is a natural reaction.”

Dr MacGregore said that the study was the first to show the mineral was a natural compound.

“There is no organic compound present in the solarium material,” he said.

The team found that the reaction occurs when the sun’s ultraviolet rays strike the sand, releasing chemicals and a mineral called silicate that reacts with the organic compound.

The reaction then produces a new mineral called calcium oxide.

“We have found that calcium oxide is a mineral that is stable at low temperatures, at very low pressures and very high pressures, so it’s really the highest concentration of calcium oxide that we have seen,” Dr MacGrego said.

Dr Macgregor said that it was not the first time solarium had been found.

“It’s not the only mineral in the world with a very low concentration of the mineral, but we have a lot of other things like bauxite, which is another mineral that has a higher concentration of silicate in the material, and that’s something that is quite rare,” he explained.

“But when you have a mineral like this, you have to look at it with a bit of scepticism, because there’s not that much information out there.”

Dr McGregor said the study did not mean that solarium could be used in Australia, as there was no scientific evidence to support its use in the industry.

“The research has shown that the material has a good thermal stability, which makes it an ideal mineral for use in commercial production of solarium,” he added.

“However, there is still some research to be done to understand exactly how the material is produced and whether it’s a biodegradable or toxic material.”
