Travertine deposits preserve an invaluable record of both ancient and modern fluid flow. The goal of this study is to reconstruct spatial and temporal patterns in travertine deposition associated with tectonic and climatic controls along the Lucero Uplift in New Mexico, USA. Uranium‐series ages of travertine deposits in the Lucero Uplift range from 0.94 ± 0.01 to 592 ± 110 ka, indicating that travertine formation has been episodically active since at least ∼600 ka. We find minimal evidence to attribute glacial and interglacial cycles to travertine formation in the Lucero Uplift. δ¹³C values in travertine deposits range from 2‰ to 9‰ (Vienna Pee Dee Belemnite), δ¹⁸O values range from 21‰ to 25‰ (Vienna Standard Mean Ocean Water). Positive correlation between travertine δ¹³C and δ¹⁸O values indicate travertine formation is closely associated with various degrees of CO₂ degassing. ⁸⁷Sr/⁸⁶Sr values in travertine deposits range from 0.714 to 0.717 and (²³⁴U/²³⁸U)_i values exhibit a remarkably wide range from 3.6 to 9.3, indicative of fluid‐rock interaction during deep crustal circulation in more radiogenic basement rocks. Reconstructed δ¹³C, δ¹⁸O, and (²³⁴U/²³⁸U)_i values in the inferred deep fluid sources showed systematic variations with travertine formation ages, while ⁸⁷Sr/⁸⁶Sr values remain relatively constant. Based on dating of undeformed travertine deposits, which overlie tilted Santa Fe Group units, and high (²³⁴U/²³⁸U)_i we infer that the Santa Fe fault has not produced a ground‐rupturing earthquake within the last 490 ± 52 to 592 ± 110 ka (2σ). Our study suggest that travertine formation is driven by fluid flow facilitated by tectonic and mantle structures.

美国新墨西哥州卢塞罗隆起的钙华沉积中沿圣达菲断层带的新构造学和深地壳流体循环的记录

钙华沉积物保留了古代和现代流体流动的宝贵记录。这项研究的目的是在美国新墨西哥州的卢塞罗隆起地区重建与构造和气候控制有关的钙华沉积的时空格局。卢塞罗隆起的钙华铀系列年龄在0.94±0.01至592±110 ka范围内，这表明钙华形成至少在约600 ka以来一直具有附加作用。我们发现极少的证据可以将冰川和冰川间的周期归因于Lucero隆起中的钙华形成。δ ¹³在石灰沉积物C值的范围从2‰至9‰（维也纳小便Dee箭石），δ ^18个O值的范围从21‰至25‰（维也纳标准平均海水）。钙华呈正相关δ ¹³C和δ ^18个O值指示石灰形成密切具有不同程度的CO相关的₂脱气。钙华沉积物中的⁸⁷ Sr / ⁸⁶ Sr值在0.714至0.717之间，（²³⁴ U / ²³⁸ U）_i值在3.6至9.3之间显示出很大的范围，这表明在地层深层循环中，在放射性更高的地下岩石中，流体与岩石之间的相互作用。重构的δ ¹³ C，δ ¹⁸ O，和（²³⁴ U / ²³⁸ U）_我在推断深流体源值显示出与石灰形成时代的系统变化，而⁸⁷ SR /⁸⁶ Sr值保持相对恒定。基于未变形石灰沉积物，其覆盖倾斜圣菲组单位，和高（约会²³⁴ U / ²³⁸ U）_我我们推断，圣达菲故障没有产生内最后490±52至592接地破裂地震± 110 ka（2σ）。我们的研究表明，钙华的形成是由构造和地幔结构促进的流体流动驱动的。
