Abstract

This paper describes the creation of a consistent database of the far-from-equilibrium dissolution rates in aqueous fluids of the major non-silicate minerals including carbonates, sulfates, phosphates, oxides and hydroxides. This work, based on the regression of available dissolution rate data normalized to their BET surface area as a function of pH and temperature, was performed using equations described in Heřmanská et al. (2022, 2023). For carbonate minerals, an additional term was added to account for the slowing of rates in response to increasing aqueous bicarbonate and carbonate concentration. All rate equations have been incorporated into a computer accessible database allowing for the direct application of these rates to assess the temporal evolution of chemical mass transfer in laboratory and field-based systems. It is anticipated that such applications will lead to further advances in our understanding the reaction rates of individual minerals and of natural water-rock interaction in the future.

一个全面和一致的矿物溶解率数据库：第三部分：非硅酸盐矿物，包括碳酸盐，硫酸盐，磷酸盐，卤化物和氢氧化物矿物

本文描述了主要非硅酸盐矿物（包括碳酸盐、硫酸盐、磷酸盐、氧化物和氢氧化物）在含水流体中非平衡溶解速率的一致数据库的创建。这项工作基于对可用溶解率数据的回归，将其归一化为其BET表面积作为pH和温度的函数，使用Heřmanská等人（2022,2023）中描述的方程进行。对于碳酸盐矿物，增加了一个额外的术语，以说明随着碳酸氢盐水溶液和碳酸盐浓度的增加，速率变慢。所有速率方程都已纳入计算机可访问的数据库，允许直接应用这些速率来评估实验室和现场系统中化学传质的时间演变。预计这些应用将导致我们对未来单个矿物和天然水岩相互作用的反应速率的进一步了解。

期刊介绍： Chemical Geology is an international journal that publishes original research papers on isotopic and elemental geochemistry, geochronology and cosmochemistry. The Journal focuses on chemical processes in igneous, metamorphic, and sedimentary petrology, low- and high-temperature aqueous solutions, biogeochemistry, the environment and cosmochemistry. Papers that are field, experimentally, or computationally based are appropriate if they are of broad international interest. The Journal generally does not publish papers that are primarily of regional or local interest, or which are primarily focused on remediation and applied geochemistry. The Journal also welcomes innovative papers dealing with significant analytical advances that are of wide interest in the community and extend significantly beyond the scope of what would be included in the methods section of a standard research paper.
