Comparative Crystal Chemistry of Dense Oxide Minerals

Oxygen is the most abundant element in the Earth, constituting about 43 percent by weight of the crust and mantle. While most of this mass is incorporated into silicates, the next most abundant mineral group in the planet is the oxides. The oxide minerals are generally considered to be those oxygen-based minerals that do not contain a distinct polyanionic species such as OH, CO3, SO4 PO4, SiO4,...

The Crystal Structure of Minerals

From crystal to glass-like thermal conductivity in crystalline minerals.

The ability of some materials with a perfectly ordered crystal structure to mimic the heat conduction of amorphous solids is a remarkable physical property that finds applications in numerous areas of materials science, for example, in the search for more efficient thermoelectric materials that enable to directly convert heat into electricity. Here, we unveil the mechanism in which glass-like t...

THE CRYSTAL CHEMISTRY OF Li-BEARING MINERALS WITH THE MILARITE-TYPE STRUCTURE: THE CRYSTAL STRUCTURE OF END-MEMBER SOGDIANITE

The crystal structure of end-member sogdianite from the Dara-i-Pioz alkaline massif, northern Tajikistan, a 10.1240(3), c 14.3198(5) Å, V 1271.1(1) Å3, space group P6/mcc, Z = 2, has been refined to an R index of 2.0% using 576 observed (|Fo | > 4sF) reflections collected with single-crystal diffractometer with MoKa X-radiation. Electron-microprobe analysis gives a composition (Zr1.98 Hf002)S2....
