The rock is approximately 2.5 billion years old. Dark bands are iron oxides (hematite, magnetite), reddish bands are chert with iron oxide inclusions (jasper), and gold bands are amphibole and quartz.

Under the Earth’s surface, just above the planet’s iron metal core, lies the core–mantle boundary (CMB). This extreme region separates the planet’s outer core from the thick layer of molten rock ...

Using iron oxide to determine when the Nullarbor dried up was a very novel technique, said Tim Cohen, a geomorphologist at the University of Wollongong. "It's pretty unusual. This is the first ...

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, ...

People from cultures across the world have been looking at Mars since ancient times. Because it appears reddish, it has often been called the red planet.

Iron oxide, found in rust on old metal machinery, is the compound that colors rocks and dust on Mars’ surface reddish brown. Lars Hammar/Flickr, CC BY-NC-SA. In my current research on exoplanets ...

Iron oxide 'oxygen sponge' doubles green hydrogen production efficiency by targeting atomic-level active sites. by Pohang University of Science and Technology.

The rocks contain iron oxides that sank to the bottom of oceans long ago, forming dense layers that eventually turned to stone. The study published this week in Nature Geoscience suggests the iron ...
