Geochemistry: Rare mineral found on EarthVolcanic rocks from Israel contain the first known occurrence on Earth of a titanium-rich mineral called tistarite. The discovery suggests that deep-Earth chemistry may differ from what scientists had suspected....

New mineral resource assessments conducted by the United States Geological Survey identified significant resources outside of China. Although China is the world leader in rare earth production, they only control about 36% of the world's reserves. This provides an opportunity for other countries to ...
Computers might also boost efforts to find rare minerals. Researchers have proposed an artificial intelligence (AI) system that could study a database of rare earth minerals, recognize patterns, and then enable it to spot new potential matches. ...
Rare earth isn't actually rare — there's an estimated 99 million tons of it in the Earth's crust — though it is hard to find large quantities of the metal in one spot. Before about 1995, barely anyone paid attention to the mineral, but demand has skyrocketed since. Why? Because ...
The work estimates a Mineral Resource to a depth of ~500m below mean sea level (MSL). However, previous exploration drilling showed mineralization continues to about 1km MSL.According to the MRE, about 17% of the Total Rare Earth Oxide (TREO) content estimated at Fen is neodymium oxide (...

In the paper, a team of international researchers report the rare scientific discovery they found in the mine: a “super-deep” diamond encasing the mineral calcium silicate perovskite (CaSiO3), which is the fourth-most abundant mineral in the Earth but has never been found in nature until no...
