Data for: Modification of mantle rocks by plastic flow below spreading centers: Fe isotopic and fabric evidence from the Luobusa ophiolite, Tibet

The attached files present a systematic dataset of the Fe isotopic compositions of ophiolitic chromitites and dunites, both of our own and those published ones, and parameters for modeling the outward diffusion of Fe from olivine grains enclosed in chromite. Such a dataset has great implications for understanding how chromitites and their associated peridotites are physico-chemically modified by mantle flows. Please see detailed data interpretation in our paper “Modification of mantle rocks by plastic flow below spreading centers: Fe isotopic and fabric evidence from the Luobusa ophiolite, Tibet”, and contact us if there were any questions. Many thanks.

本附件所附文件提供了一套系统性数据集，涵盖本团队实测与已公开发表的蛇绿岩套铬铁矿矿石（ophiolitic chromitites）及纯橄榄岩（dunites）的铁同位素组成（Fe isotopic compositions）数据，同时包含用于模拟铬铁矿（chromite）包裹橄榄石颗粒（olivine grains）中铁元素向外扩散过程的相关参数。本数据集对揭示铬铁矿矿石及其伴生橄榄岩如何受地幔流（mantle flows）作用发生物理-化学改造具有重要科学意义。详细的数据解译内容请参阅本团队发表的论文《扩张中心下方塑性流变（plastic flow）改造地幔岩石：来自西藏罗布莎蛇绿岩（Luobusa ophiolite）的铁同位素与组构证据（fabric evidence）》（Modification of mantle rocks by plastic flow below spreading centers: Fe isotopic and fabric evidence from the Luobusa ophiolite, Tibet），如有任何疑问欢迎随时联系我们。非常感谢。
