Oxide Class of Minerals

Geologists found evidence in the way enigmatic sandstones called Tava formed in the Rocky Mountains hundreds of millions of years ago.

In new research, University College London's Professor Mark Altaweel and his colleagues analyzed 32 inscribed baked bricks from Mesopotamia from the 3rd-1st millennia BCE (the reigns of 12 Mesopotamian kings).

NASA scientists revealed the sample collected by the OSIRIS-REx mission from near-Earth asteroid Bennu for the first time Wednesday.

NASA said during a live stream Wednesday that Bennu asteroid samples collected by the OSIRIS-Rex mission contain water, carbon and organic molecules - the building blocks of life.

The Zhurong rover has found evidence of water on dune surfaces on modern Mars by providing key observational proof of liquid water at low Martian latitudes, according to a study led by Prof. Qin Xiaoguang from the Institute of Geology and Geophysics (IGG) of the Chinese Academy of Sciences (CAS).

Rocks can hold clues to history dating back hundreds of millions of years.

Research led by Curtin University reveals that Earth's largest iron ore deposits—in the Hamersley Province of Western Australia—are about one billion years younger than previously believed, a discovery which could greatly boost the search for more of the resource.

Newfound rocks on Mars suggest the planet may have once sported an oxygen-rich atmosphere, making it more Earth-like and hospitable to life than previously thought.

Spectral analysis of the mystery asteroid Phaethon reveals its composition at last.

Satellites have relied on solar panels for decades to convert sunlight into electricity using photovoltaic cells, but damage from certain types of radiation can cause them to...

What is a mineral? By Donald Peck (further edits by other mindat.org members) There are several ways to define what a mineral is depending on how formal you want to be. A completely informal ...

Scientists in Japan have found a common substance that can reversibly and rapidly store and release relatively large amounts of low-grade heat without decomposing. The research could lead to more efficient reuse of industrial waste heat. The results were published in the journal Nature Communications and were a collaboration between scientists at Tohoku University's Institute for Materials Research and Rigaku…

Northwestern University-led researchers have discovered a new way that nature cycles phosphorus, a finding that uncovers a missing piece of Earth's puzzling phosphorus cycle.

Geologists uncovered ancient rocks in Greenland that bear the oldest remnants of Earth's early magnetic field. The results potentially extend the age of the Earth's magnetic field by hundreds of millions of years, and may shed light on the planet's early conditions that helped life take hold.

Oxides of tin (SnxOy) are found in many of modern technologies due to their versatile nature. The multivalent oxidation states of tin—Sn2+ and Sn4+—impart tin oxides with electroconductivity, photocatalysis, and various functional properties. For the photocatalysis application of tin oxides, a narrow bandgap for visible-light absorption is indispensable to utilize a wide range of solar energy. Hence, the discovery…

Samples of the near-Earth asteroid (162173) Ryugu were brought to Earth by JAXA's Hayabusa-2 spacecraft.
