Squeezing water from a stone: H2O in nominally anhydrous minerals from granulite xenoliths and deep, hydrous fractional crystallization

This is a mineral chemistry dataset on lower crustal granulites from the State Line District kimberlite, Colorado, USA. We report mineral major element compositions and mineral water contents analyzed by SIMS at the Caltech Microanalysis Facility. The minerals included are garnet, orthopyroxene, and clinopyroxene, and accessory minerals.

本数据集为美国科罗拉多州State Line District金伯利岩中下部地壳麻粒岩的矿物化学数据集。我们报道了通过加州理工学院微分析设施采用二次离子质谱（SIMS）分析得到的矿物主量元素组成及矿物含水量。涉及的矿物包括石榴子石、斜方辉石、单斜辉石及副矿物。
