The effects of small amounts of H2O, CO2 and Na2O on the partial melting of spinel Lherzolite in the system CaO-MgO-Al2O3-SiO2 ± H2O ± CO2 ± Na2O at 1·1GPa
Abstract
<p>The effects of small amounts of H<sub>2</sub>O (<4wt % in the melt) on the multiply saturated partial melting of spinel lherzolite in the system CaO-MgO-Al<sub>2</sub>O<sub>3</sub>-SiO<sub>2</sub> ± Na<sub>2</sub>O ± CO<sub>2</sub> have been determined at 1·1GPa in the piston-cylinder apparatus. Electron microprobe analysis and Fourier transform infrared spectroscopy were used to analyse the experimental products. The effects of H<sub>2</sub>O are to decrease the melting temperature by 45°C per wt % H<sub>2</sub>O in the melt, to increase the Al<sub>2</sub>O<sub>3</sub> of the melts, decrease MgO and CaO, and leave SiO<sub>2</sub> approximately constant, with melts changing from olivine- to quartz-normative. The effects of CO<sub>2</sub> are insignificant at zero H<sub>2</sub>O, but become noticeable as H<sub>2</sub>O increases, tending to counteract the H<sub>2</sub>O. The interaction between H<sub>2</sub>O and CO<sub>2</sub> causes the solubility of CO<sub>2</sub> at vapour saturation to increase with increasing H<sub>2</sub>O, for small amounts of H<sub>2</sub>O. Neglect of the influence of CO<sub>2</sub> in some previous studies on the hydrous partial melting of natural peridotite may explain apparent inconsistencies between the results. The effect of small amounts of H<sub>2</sub>O on multiply saturated melt compositions at 1·1GPa is similar to that of K<sub>2</sub>O, i.e. increasing H<sub>2</sub>O or K<sub>2</sub>O leads to quartz-normative compositions, but increasing Na<sub>2</sub>O produces an almost opposite trend, towards nepheline-normative compositions.</p>
