Silicate minerals

TL;DR: In this article, the authors measured the U-series disequilibria of the main basaltic rivers from the Deccan Trap region (India) and found that the deformation of carbonates, releasing dissolved U at secular equilibrium, plays a key role in the preferential release of 234U from silicate minerals.

TL;DR: In this article, the acidized water glass (AWG) was used as a depressant for the substitution of soda ash plus sodium lignosulfonate (SLS) in fluorite flotation.

TL;DR: It is revealed that trichloroethylene (TCE) can be efficiently oxidized during the oxygenation of reduced nontronite at pH 7.5, whereas the reduction was negligible under anoxic conditions.

TL;DR: In this paper, the authors used density functional theory to calculate the Si isotope fractionation factors for mantle silicate minerals, including olivine, wadsleyite, ringwoodite, majorite, pyroxenes, garnet (pyrope), majorite and Mg-perovskite.

TL;DR: In this article, a double peak in the 1430-1515 cm y1 3 region in the FT-IR spectrum, attributable to the CO 2y group, showed that carbon dioxide is 3 present in the ground diopside, in the same form as in synthetic and natural silicate glasses after dissolution of CO at high temperatures and pressures relevant to the magma state.
