Abstract We report results from multi-anvil (MA) and laser-heated diamond anvil cell (LH-DAC) experiments that synthesize high-pressure phases, including bridgmanite, ferropericlase, stishovite, and ultramafic liquid, in the presence of an argon-rich fluid. The goal of the experiments is to constrain the equilibrium distribution of argon in magma ocean environments. Argon concentrations in LH-DAC experiments were quantified by electron microprobe analysis, while argon concentrations in MA experiments were quantified by laser-ablation mass spectrometry and electron microprobe analysis. Our LH-DAC experiments demonstrate that argon solubility in ultramafic liquid is near or above 1.5 wt.% at conditions between 13–101 GPa and 2300–6300 K. Argon concentrations in bridgmanite and ferropericlase synthesized in LH-DAC experiments range from below detection to 0.58 wt.%. Argon concentrations in bridgmanite and ferropericlase synthesized in MA experiments range from below detection to 2.16 wt.% for electron microprobe measurements and laser-ablation measurements. We interpret this wide range of argon concentrations in minerals to reflect the variable presence of argon-rich fluid inclusions in analytical volumes. Our analyses therefore provide upper limit constraints for argon solubility in high-pressure minerals ( D bridgmanite − melt Ar D ferropericlase − melt Ar

岩浆海洋结晶过程中氩气的不相容性

摘要 我们报告了多砧 (MA) 和激光加热金刚石砧座 (LH-DAC) 实验的结果，这些实验在富含氩气的情况下合成高压相，包括桥锰矿、铁镁石、stishovite 和超镁铁质液体。体液。实验的目标是限制岩浆海洋环境中氩气的平衡分布。LH-DAC 实验中的氩浓度通过电子微探针分析进行量化，而 MA 实验中的氩浓度通过激光烧蚀质谱和电子微探针分析进行量化。我们的 LH-DAC 实验表明，在 13-101 GPa 和 2300-6300 K 之间的条件下，氩在超基性液体中的溶解度接近或高于 1.5 wt.%。在 LH-DAC 实验中合成的桥锰矿和方镁石中的氩浓度范围从低于检测到 0.58 wt.%。在 MA 实验中合成的桥锰矿和方镁石中的氩浓度范围从低于检测到电子微探针测量和激光烧蚀测量的 2.16 wt.%。我们解释了矿物中这种广泛的氩浓度，以反映分析体积中富氩流体包裹体的可变存在。因此，我们的分析为氩在高压矿物中的溶解度提供了上限约束（D 桥锰矿 - 熔体 Ar D 铁方镁石 - 熔体 Ar 我们解释了矿物中这种广泛的氩浓度，以反映分析体积中富含氩的流体包裹体的可变存在。因此，我们的分析为氩在高压矿物中的溶解度提供了上限约束（D 桥锰矿 - 熔体 Ar D 铁方镁石 - 熔体 Ar 我们解释了矿物中这种广泛的氩浓度，以反映分析体积中富含氩的流体包裹体的可变存在。因此，我们的分析为氩在高压矿物中的溶解度提供了上限约束（D 桥锰矿 - 熔体 Ar D 铁方镁石 - 熔体 Ar
