Your blood is also red because of a mixture of iron and oxygen in a molecule called hemoglobin. So in a way, the ancient ...

Moab makes for the perfect homebase to explore the Southwest's iconic red rocks landscape. Here's what to know about camping.

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

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.

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 waves of colourful rock within the specimen are made up of black and red bands of iron oxide (mostly haematite and some magnetite), interspersed with lighter sedimentary rock (silica). Scientists ...

Huge iron ore deposits in Western Australia's Hamersley Province formed when major tectonic events led to the breakup of supercontinent Columbia and to the amalgamation of Australia.

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 ...

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

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 ...
