Chlorine, lithium, and boron are trace elements in rhyolite but are enriched in groundwater flowing through rhyolite because they tend to partition into the fluid phase during high‐temperature fluid‐rock reactions. We present a large data set of major element and δ³⁷Cl, δ⁷Li, and δ¹¹B compositions of thermal water and rhyolite from Yellowstone Plateau Volcanic Field (YPVF). The Cl/B, Cl/Li, δ³⁷Cl (−0.2‰ to +0.7‰), and δ¹¹B (−6.2‰ to −5.9‰) values of alkaline‐chloride thermal waters reflect high‐temperature leaching of chlorine, lithium, and boron from rhyolite that has δ³⁷Cl and δ¹¹B values of +0.1‰ to +0.9‰ and −6.3‰ to −6.2‰, respectively. Chlorine and boron are not reactive, but lithium incorporation into hydrothermal alteration minerals result​s in a large range of Cl/Li, B/Li, and δ⁷Li (−1.2‰ to +3.8‰) values in thermal waters. The relatively large range in δ⁷Li values of thermal waters reflects a large range of values in rhyolite. Large volumes of rhyolite must be leached to account for the chloride, lithium and boron fluxes, implying deep groundwater flow through rhyolite flows and tuffs representing Yellowstone's three eruptive cycles (∼2.1 Ma). Lower Cl/B values in acid‐sulfate waters result from preferential partitioning of boron into the vapor phase and enrichment in the near‐surface water condensate. The Cl/B, Cl/Li, δ⁷Li (−0.3‰ to +2.1‰), and δ¹¹B (−8.0‰ to −8.1‰) values of travertine depositing calcium‐carbonate thermal waters which discharge in the northern and southern YPVF suggest that chlorine, lithium, and boron are derived from Mesozoic siliciclastic sediments which contain detrital material from the underlying metamorphic basement.

黄石高原火山场水热系统中氯，锂，硼与δ37Cl，δ7Li和δ11B的系统关系

氯，锂和硼是流纹岩中的微量元素，但在流经流纹岩的地下水中富集，因为它们在高温流体-岩石反应中倾向于分配到液相中。我们目前主要元件的一个大的数据集和δ ³⁷氯，δ ⁷ Li和δ ¹¹的热水乙组合物和从黄石高原火山字段（YPVF）流纹岩。的CL / B，CL /栗，δ ³⁷氯（-0.2‰至+ 0.7‰），和δ ¹¹ B（-6.2‰至-5.9‰）的碱性氯化值温泉水反映高温氯的浸出，锂，和从流纹岩硼具有δ ³⁷ Cl和δ ¹¹B值分别为+ 0.1‰至+ 0.9‰和-6.3‰至-6.2‰。氯和硼不是反应性的，但锂掺入热液蚀变矿物在大范围CL /锂，B /锂的结果S，和δ ⁷李（-1.2‰至+ 3.8‰）值在热水域。该范围相对较大δ ^7个温泉水的李值反映了大范围流纹岩的值。必须浸出大量流纹岩，以说明氯，锂和硼的通量，这意味着流经流纹岩和凝灰岩的深层地下水流代表了黄石的三个喷发周期（约2.1 Ma）。酸性硫酸盐水中较低的Cl / B值是由于硼优先分配到气相中以及近地表水冷凝物中的富集而产生的。该CL / B，CL /李δ ⁷立（-0.3‰至+ 2.1‰），和δ ¹¹ B（-8.0‰至-8.1‰）沉积钙碳酸盐温泉水，其放电在北部和南部YPVF表明氯，锂和硼是石灰的值源自中生代硅质碎屑沉积物，其中含有来自潜在变质基底的碎屑物质。
