项目摘要

This project is a study of hydrothermal alteration and weathering of large, subaerial peridotite massifs that form the mantle section of the Samail ophiolite in Oman. Peridotite is a rock comprised mainly of the mineral olivine (gemstone name, 'peridot'), and it comprises most of the Earth's upper mantle but is normally shielded from reaction with surface rocks by the oceanic and continental crust. Plate tectonic collisions coupled with erosion expose peridotite at the surface, where it reacts rapidly with surface waters. It is proposed to investigate formation of hydrated minerals and solid carbonate minerals via reaction of peridotite with near-surface waters in (a) active, ongoing low-T systems, probably at 30 to 60°C and involving meteoric water, and (b) older, fossil high-T systems which may have reached ~ 200°C, formed completely carbonated peridotites - in which all Mg and Ca are in solid carbonate minerals - called listwanites. The high-T system may have involved fluids from carbonate bearing metasediments beneath the ophiolite. They will constrain the temperatures, timing, and fluid composition of both the active low-T systems and fossil high-T systems through chemical and isotopic analysis. The goal is to constrain factors that control efficient carbonation of peridotite, expand thermodynamic models of phase equilibria incorporating solid solution models, and provide cross-calibration of isotope thermometers. It is hypothesized that complete carbonation of peridotite occurred at pressures, temperatures and fluid compositions close to the conditions at which olivine carbonation rates are maximized, and that rapid rates facilitate a positive feedback between volume change, reaction-induced cracking, permeability, and reaction rate. A key step in testing this hypothesis is to confirm preliminary inferences by the group about the conditions of peridotite carbonation. One might expect decreasing permeability and armoring of reactive surfaces to limit the extent of reaction, but natural peridotite carbonation can and does go to completion, in which all Mg and Ca (and much of the Fe) are incorporated in carbonate minerals. Similarly, addition of H2O commonly produces 100% hydration of Mg in large volumes of rock. This study will characterize the chemical and physical processes that lead to rapid, extensive peridotite hydration and carbonation.Reaction of CO2 from ground water or seawater with peridotite forms abundant carbonate minerals, in processes that are driven by a vast reservoir of available, chemical potential energy. Carbonation of the abundant mineral, olivine, is faster than for other abundant, rock-forming minerals. Recently, several papers have emphasized the potential for in situ carbonation of peridotite, either via reaction with injected, CO2-rich fluids, or simply via enhanced reaction with surface-derived seawater. Optimal peridotite carbonation conditions could yield CO2 uptake of ~ 1 billion tons/km3 of peridotite/yr, and could provide an enormous reservoir for up to ~ 100 trillion tons of CO2. Results of this study will facilitate future design of engineered, in situ techniques for in situ geological CO2 capture and storage (CCS). In particular, we need to learn how natural peridotite carbonation processes avoid potential limitations due to decreasing permeability and loss of reactive surface area during precipitation of carbonate minerals in pore space. If these negative feedbacks can be overcome in an engineered system, in situ storage in solid carbonate minerals may be cost competitive with more conventional injection of CO2 into subsurface pore space for CCS. In situ mineral carbonation poses fewer property problems and leakage hazards than injection of fluid into pore space, providing stable, inert, non-toxic storage.
该项目是对阿曼Samail蛇绿岩地幔部分的大型陆上橄榄岩的热液蚀变和风化作用的研究。 橄榄岩是一种主要由矿物橄榄石(宝石名称,'橄榄')组成的岩石,它包括地球上地幔的大部分,但通常被海洋和大陆地壳屏蔽,不与地表岩石反应。板块构造碰撞加上侵蚀使橄榄岩暴露在地表,在那里它与地表沃茨迅速反应。 建议通过橄榄岩与近地表沃茨的反应来研究水合矿物和固体碳酸盐矿物的形成:(a)活跃的、持续的低温度系统,可能在30至60°C,并涉及大气降水;和(B)较老的、化石高温度系统,可能达到~ 200°C,形成完全碳酸化的橄榄岩--其中所有的镁和钙都是固体碳酸盐矿物--被称为利斯特万岩。高温系统可能涉及蛇绿岩下含碳酸盐变质沉积物的流体。他们将通过化学和同位素分析来限制活跃的低T系统和化石高T系统的温度、时间和流体成分。 我们的目标是限制因素,控制有效的碳酸化橄榄岩,扩大相平衡的热力学模型,将固溶体模型,并提供交叉校准同位素温度计。据推测,橄榄岩的完全碳酸化发生在压力,温度和流体成分接近的条件下,橄榄石碳酸化速率最大化,快速的速度促进体积变化,反应诱导的开裂,渗透性和反应速率之间的正反馈。检验这一假设的一个关键步骤是确认小组关于橄榄岩碳酸化条件的初步推断。人们可能会期望降低渗透率和反应表面的装甲来限制反应的程度,但天然橄榄岩碳酸化可以并且确实完成,其中所有的Mg和Ca(以及大部分Fe)都被纳入碳酸盐矿物中。类似地,加入H2O通常在大量岩石中产生100%的Mg水合。本研究将描述导致橄榄岩快速、广泛水化和碳酸化的化学和物理过程。地下水或海水中的CO2与橄榄岩反应形成丰富的碳酸盐矿物,该过程由巨大的可用化学势能驱动。丰富的矿物橄榄石的碳酸化作用比其他丰富的岩石形成矿物快。最近,几篇论文强调了橄榄岩原位碳酸化的潜力,无论是通过与注入的富CO2流体反应,还是简单地通过与表面衍生海水的增强反应。最佳的橄榄岩碳酸化条件可产生约10亿吨/立方公里橄榄岩/年的CO2吸收,并可提供高达约100万亿吨CO2的巨大储库。这项研究的结果将有助于未来设计的工程,在原位技术,在原位地质二氧化碳捕获和储存(CCS)。特别是,我们需要了解天然橄榄岩碳酸化过程如何避免由于孔隙中碳酸盐矿物沉淀过程中渗透率降低和反应表面积损失而造成的潜在限制。如果这些负反馈可以在工程系统中被克服,在固体碳酸盐矿物中的原位储存可能比用于CCS的更常规的将CO2注入地下孔隙空间具有成本竞争力。原位矿物碳酸化比向孔隙空间注入流体造成的性质问题和泄漏危险更少,提供稳定、惰性、无毒的储存。
