Identifying a mineral might sound straightforward: analyze its chemistry, compare it to known minerals and voilà. But for geologists, this process can be a time-consuming puzzle requiring specialized expertise and a lot of manual calculation. Now, a team of researchers at Rice University’s Department of Earth, Environmental and Planetary Sciences has developed MIST — Mineral Identification by Stoichiometry — the first online tool capable of automatically identifying hundreds of different mineral species from their chemical composition using a carefully designed rules-based algorithm.

A new study, led by University of Hawai‘i at Mānoa oceanographers, revealed that the ocean is acidifying even more rapidly below the surface in the open waters of the North Pacific near Hawai‘i. 

More trees will cool the climate and suppress fires, but mainly if planted in the tropics, according to a new UC Riverside study. 

The subducted oceanic crusts are regarded as the major source of lower-mantle heterogeneity. However, the limited knowledge about the physical properties of major components in the subducted oceanic crusts prevents us from fully understanding the complex features of the related geophysical anomalies. Here, we comprehensively investigated the phase transition of (Al, H)-bearing stishovite at simultaneously high P-T conditions. These results contribute to our understanding on the complex depth distribution of the mid-lower mantle seismic scatterers.
