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.

全面一致的矿物溶解速率数据库:第 III 部分:非硅酸盐矿物,包括碳酸盐、硫酸盐、磷酸盐、卤化物和氢氧矿物



本文介绍了如何创建一个一致的数据库,该数据库记录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)在水性流体中的远非平衡溶解速率。这项工作基于可用溶出速率数据的回归,作为 pH 和温度的函数归一化为其 BET 表面积,使用 Heřmanská 等人(2022 年、2023 年)中描述的方程进行。对于碳酸盐矿物,增加了一个附加项,以解释响应碳酸氢盐水和碳酸盐浓度增加而减慢的速率。所有速率方程都已合并到计算机可访问的数据库中,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。预计此类应用将导致我们对未来单个矿物的反应速率和天然水岩相互作用的理解取得进一步进展。
