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.

实验成因与天然熔体包裹体（melt inclusions）及其寄主橄榄石（host olivines）的电子探针（Electron Microprobe）测试数据。本数据集以重量百分比浓度剖面形式呈现，剖面轨迹从包裹体一侧的寄主橄榄石起始，横穿包裹体中心后延伸至另一侧的橄榄石内部。实验于1大气压气体混合炉内开展，实验流程依次包含24小时均质化处理阶段，随后进入受控冷却阶段。本数据集同时收录了三处未受热样品的测试数据：(1) 夏威夷冒纳罗亚火山帕帕科莱阿（Papakolea, Hawaii (Mauna Loa)），样品取自本次实验起始原料所用橄榄石海滩砂的同一储藏堆；(2) 夏威夷基拉韦厄伊基（Kilauea Iki, Hawaii）；(3) 辉玻无球粒陨石（Shergottite）Yamato 980459。
