论文摘要
我们通过全场和平均田间建模研究了溶质阻力对富含橄榄石岩石的谷物生长（GG）动力学的影响。考虑到杂质在晶界迁移上施加的阻力，可以对橄榄石GG动力学的实验室和自然限制进行调解。溶质阻力是在完整的现场级别框架和平均场模型中实现的，该模型明确解释了晶粒尺寸的分布。在全场结果上校准了平均场模型后，这两个模型既能够再现实验室GG动力学，并预测与不同地质环境中橄榄岩Xenoliths中观察结果一致的晶粒大小。
We investigate the effect of solute drag on grain growth (GG) kinetics in olivine-rich rocks through full field and mean field modelling. Considering a drag force exerted by impurities on grain boundary migration allows reconciling laboratory and natural constraints on olivine GG kinetics. Solute drag is implemented in a full field level-set framework and on a mean field model, which explicitly accounts for a grain size distribution. After calibration of the mean field model on full field results, both models are able to both reproduce laboratory GG kinetics and to predict grain sizes consistent with observations in peridotite xenoliths from different geological contexts.
