Experimental synthesis of Fe-bearing olivine at near-solidus temperatures and its decomposition during longtime heating
نویسندگان
چکیده
Several investigations have demonstrated that olivine may be used to simulate geochemical and cosmochemical reactions. Since in extra-terrestrial samples has varying forsterite numbers natural contains inevitable impurities, synthetic with the requisite number been prepared for various experimental research. This study aimed synthesize Fe-bearing via experiments conducted at near-solidus temperatures elucidate formation decomposition mechanisms of obtained olivine. Specifically, we attempted Fo60 (Forsterite = 100 × Mg/(Mg + Fe) 60) using a mixture analytical-grade SiO2, MgO, Fe2O3. To clarify stability olivine, temperature range (1350–1500 °C) heating durations (1.5 h or 15 h) were controlled under constant oxygen fugacity QFM-1 log units.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Methane generation during experimental serpentinization of olivine.
Oze et al. (1) observed generation of methane (CH4) during experimental serpentinization of olivine, and use the results to make inferences about sources of methane in natural serpentinites. Their data interpretation, however, is directly contradicted by results of prior studies, critically undermining the credibility of their conclusions. Several prior studies conducted using experimental meth...

Temperatures, heating rates and vapour pressures in near-surface snow at the South Pole
A finite-volume model is used to simulate 9 years (1995–2003) of snow temperatures at the South Pole. The upper boundary condition is skin-surface temperature derived from routine upwelling longwave radiation measurements, while the lower boundary condition is set to the seasonal temperature gradient at 6.5m depth, taken from prior measurements at the South Pole. We focus on statistics of tempe...
