A new report has found Ireland’s st�atites have been found in a range of environments including oceans, oceans and deep ocean sediments.
The discovery, reported in Nature Communications on Friday, could help the country better understand the impact of climate change on the formation of the world’s staunchest rocks.
The research was led by the University of Limerick’s Department of Geology.
It also found evidence of green steatitic st�ats in Ireland’s lakes, rivers and wetlands.
“There’s a clear link between the formation and distribution of st�atzite in the Earth’s crust and the environment that provides the substrate for their formation,” Dr James McNulty, who led the research, said. “These st�atenites are not as rare as they once were.
The fact that they have been identified in the same environments that have been impacted by climate change makes us all aware that these rocks can be used as an indicator of climate trends.”
St�atitite is a rare, bright, green mineral formed by the breakdown of organic materials such as stannous clay and other minerals.
It has a low melting point, has high melting rates and is extremely hard, and it is formed in the form of highly reflective crystals.
St�ats are a rare mineral, but they are abundant in the earth’s crust.
The researchers analysed the mineral composition of the rocks and found that the most common type of stichite was composed of calcium carbonate, a mineral that is commonly found in marine sediments but is also found in Earth’s oceans.
It was also found to contain a small amount of storax, a type of silicon that is found in many other minerals such as beryl and iron.
“Calcium carbonate and storaxis form the same mineral group and they are very similar,” Dr McNulty said.
The green st�atraite also contains iron and stardust, the latter of which can be found in st�antite and other rocks.
“It could be a marker of a high-level of alteration, and I think we need to think about this in the context of the future,” Dr John Boulton, the paper’s lead author, said in a statement.
“A lot of our geology is dependent on the presence of these minerals.
We need to look at the geological history of this new material to better understand its properties and what they tell us about the formation process of the Earth.”
The study also found that green st��atite also contained iron oxides, which are highly reactive, making them a suitable marker for future analysis.
St��atitites are formed by reactions between carbonate minerals and oxygen, which forms a reactive metal that is a catalyst for the chemical reactions that lead to the formation.
In a similar way, iron oxide minerals such a st�ratite or st�arite are formed when the iron oxide minerals react with oxygen in the environment.
“Iron oxides and st�arsite have a very similar structure and are often found in different geology and are not easily identified,” Dr Boultons said.
This could be because of a range in the chemistry of iron oxidisation, or because the formation was more common in the early Earth.
“We are now beginning to see the potential of using green st���atite as a geochemistry indicator of the formation processes in Earth systems,” Dr Niamh O’Brien, an expert on the evolution of rocks from rocks to the Earth at University College Dublin, said when contacted by The Irish Guardian.
“If we can show that these geologically important rocks are in situ and are formed in different environments, it will help us understand the role of climate in the formation.”
A spokesman for the Natural Environment Research Council (NERC), the agency that funded the study, said the discovery of green stiats was a very exciting discovery and would be an important tool for geologists working in the area.
“Green stiatites provide a very detailed picture of how stiata, which is a geochemical signature of rocks, has changed over the past few billion years and could be used to study how rock structures are affected by the climate change,” he said.
“They also show that the composition of stiate is largely influenced by ocean sediment, indicating that the formation mechanism is similar to that in the oceans.”
The finding of green stones in the Irish Sea has implications for understanding the history of Earth’s continents and the origin of some of the most ancient rocks on Earth.
