Seismic anisotropy has been widely observed in the crust and mantle due to the crystal preferred orientation (CPO) of highly anisotropic minerals such as amphibole, though it is poorly constrained ...

The mineral amphibole is made up of tetrahedral and octahedral structures linked together in a way that creates a series of rings. New research suggests those rings -- called A-sites -- could ...

Researchers at Brown have discovered that the lattice structure of minerals such as amphibole provides a way. Better yet, the multiple isotopes of noble gases could help scientists track volatiles ...

Crocidolite asbestos is a light blueish white, consists of long and thin fibres, and is known for being the most dangerous kind of asbestos. Chrysotile asbestos is white in colour and can be ...
