Experimental study on the solubility of $ Cr^{2+} $ in olivine, orthopyroxene and spinel solid solutions
Abstract Experiments have been performed on the system MgO-$ SiO_{2} $-Cr-O at 0–2.88 GPa and 1100–1450°C, focusing on the stability of $ Cr^{2+} $ in olivine (Ol), orthopyroxene (Opx) and spinel (Sp) and its partitioning between these phases. Analytical reagent grade chemicals, MgO, $ SiO_{2} $, $...

Analytical reagent grade chemicals, MgO, $ SiO_{2} $, $ Cr_{2} $$ O_{3} $, and Cr were used to make starting mixtures. Excess Cr (50%) was then added in these mixtures to ensure that the resultant phases were in equilibrium with the metal Cr. Flux of BaO + $ B_{2} $$ O_{3} $ (%) was added for facilitating experimental equilibrium and crystal growth. Cr was used as capsule material. All phases in the product were identified by X-ray and analyzed by electron microprobe. The contents of CrO in the different phases (Ol, Opx and Sp) were calculated according to stoichiometry. The obtained results of calculation indicate that $ Cr^{3+} $ in Ol and Opx is negligible. The experimental results show: (a) with increasing temperature and decreasing pressure, $ Cr^{2+} $ solubility in Ol, Opx and Sp increases; (b) with increasing temperature, the partitioning coefficient of Mg and $ Cr^{2+} $ between Ol and Opx decreases, that between Opx and Sp increases, and that between Ol and Sp remains almost unchanged; (c) the effect of pressure on all partitioning coefficients is negligible. | ||

All phases in the product were identified by X-ray and analyzed by electron microprobe. The contents of CrO in the different phases (Ol, Opx and Sp) were calculated according to stoichiometry. The obtained results of calculation indicate that $ Cr^{3+} $ in Ol and Opx is negligible. The experimental results show: (a) with increasing temperature and decreasing pressure, $ Cr^{2+} $ solubility in Ol, Opx and Sp increases; (b) with increasing temperature, the partitioning coefficient of Mg and $ Cr^{2+} $ between Ol and Opx decreases, that between Opx and Sp increases, and that between Ol and Sp remains almost unchanged; (c) the effect of pressure on all partitioning coefficients is negligible.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cr</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">solubility</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">olivine</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">orthopyroxene</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">spinel</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">experimental study</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">O’Neill, Hugh St. C.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Seifert, Friedrich</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Chinese journal of geochemistry</subfield><subfield code="d">Science in China Press, 1985</subfield><subfield code="g">16(1997), 2 vom: Apr., Seite 139-147</subfield><subfield code="w">(DE-627)130963208</subfield><subfield code="w">(DE-600)1066729-5</subfield><subfield code="w">(DE-576)077051459</subfield><subfield code="x">1000-9426</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:16</subfield><subfield code="g">year:1997</subfield><subfield code="g">number:2</subfield><subfield code="g">month:04</subfield><subfield code="g">pages:139-147</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">https://doi.org/10.1007/BF02843392</subfield><subfield code="z">lizenzpflichtig</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-GEO</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OPC-GGO</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_22</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_40</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4012</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">16</subfield><subfield code="j">1997</subfield><subfield code="e">2</subfield><subfield code="c">04</subfield><subfield code="h">139-147</subfield></datafield></record></collection>

Experimental study on the solubility of $ Cr^{2+} $ in olivine, orthopyroxene and spinel solid solutions |
| abstract |
Abstract Experiments have been performed on the system MgO-$ SiO_{2} $-Cr-O at 0–2.88 GPa and 1100–1450°C, focusing on the stability of $ Cr^{2+} $ in olivine (Ol), orthopyroxene (Opx) and spinel (Sp) and its partitioning between these phases. Analytical reagent grade chemicals, MgO, $ SiO_{2} $, $ Cr_{2} $$ O_{3} $, and Cr were used to make starting mixtures. Excess Cr (50%) was then added in these mixtures to ensure that the resultant phases were in equilibrium with the metal Cr. Flux of BaO + $ B_{2} $$ O_{3} $ (%) was added for facilitating experimental equilibrium and crystal growth. Cr was used as capsule material. All phases in the product were identified by X-ray and analyzed by electron microprobe. The contents of CrO in the different phases (Ol, Opx and Sp) were calculated according to stoichiometry. The obtained results of calculation indicate that $ Cr^{3+} $ in Ol and Opx is negligible. The experimental results show: (a) with increasing temperature and decreasing pressure, $ Cr^{2+} $ solubility in Ol, Opx and Sp increases; (b) with increasing temperature, the partitioning coefficient of Mg and $ Cr^{2+} $ between Ol and Opx decreases, that between Opx and Sp increases, and that between Ol and Sp remains almost unchanged; (c) the effect of pressure on all partitioning coefficients is negligible. © Institute of Geochemistry, Chinese Academy of Sciences 1997 |
