Iron oxide minerals are found in rocks around the globe. Some are magnetic, and some of them rust—especially when exposed to ...

“We were trying to create a replica Martian dust in the laboratory using different types of iron oxide. We found that ferrihydrite mixed with basalt, a volcanic rock, best fits the minerals seen ...

"Iron oxides trap phosphorus because they have different charges ... Because phosphorus is a finite resource—mined from ...

Social media has been flooded with photos from the beaches on Hormuz Island in Iran, where the sand has taken on an intensely ...

At some point, iron within rocks on Mars reacted with water or water and oxygen in the air, creating iron oxide — much in the same way rust forms on Earth. Over billions of years, the iron oxide ...

Scientists have uncovered that iron oxides, previously thought to trap phosphorus, actually help convert it into a ...

Mars’s red dust may contain ferrihydrite, an iron mineral that forms in water. This suggests ancient Mars had water for ...

the iron bound up in its rocks reacted with water and oxygen in the air, similar to how rust forms here on Earth. The resulting iron oxide was then broken down into dust and was spread around the ...

In the March 4, 2025, online issue of the journal Geology, Utah State University geoscientists Jordan Jensen and Alexis Ault ...

Scientists have a new theory on why Mars is red, and it may mean that water was more widespread on the planet than previously ...
