Controlled cooling-rate experiments on olivine-hosted melt inclusions: chemical diffusion and quantification of eruptive cooling-rates on Hawaii and Mars

Electron microprobe measurements of experimental and natural melt inclusions and their host olivines. The data are presented as weight percent concentration profiles that extend from the enclosing olivine on one side of an inclusion, across the inclusion center, and then back out into the olivine on the opposite side. Experiments were conducted in a 1 atmosphere gas-mixing furnace and consisted of a 24 hour homogenization stage followed by a controlled cooling stage. We also present data from unheated samples from three locations: (1) Papakolea, Hawaii (Mauna Loa), selected from the same cache of olivine beach sands that were used as the starting materials for the experiments, (2) Kilauea Iki, Hawaii, and (3) the shergottite Yamato 980459.

本数据集收录了实验性与自然熔融包裹体的电子探针测量结果及其宿主橄榄石。数据以重量百分比浓度分布的形式呈现，范围从包裹体一侧的包围橄榄石，穿过包裹体中心，直至另一侧的橄榄石。实验在1大气压的气体混合炉中进行，包括24小时的均质化阶段，随后是受控冷却阶段。此外，我们还提供了来自三个未加热样本地点的数据：(1) 夏威夷帕帕科莱亚（莫纳罗亚），从与实验起始材料相同的橄榄石海滩沙中选取；(2) 夏威夷基拉韦厄伊基；(3) 石陨石亚马托980459。
