The use of Li/Ca, Na/Ca and Li/Mg ratios in biogenic aragonite exhibits high potential for reconstructing environmental parameters such as temperature and/or salinity. To date however, only a little is known about the mechanisms controlling the incorporation of monovalent metals such as Li and Na in aragonite. In this study, the effects of temperature and growth rate on Li and Na incorporation into abiotically precipitated aragonite were experimentally investigated. The results for aragonite overgrowths at 5, 15 and 25 °C and for the surface normalized growth rate range 10 ≤ ≤ 10 (mol/m/s) suggest that apparent distribution coefficients (i.e., ) of Li and Na are mainly controlled by mineral growth rate, whereas temperature has a minor effect. The combined effect of growth rate and temperature on and can be described as:

温度和矿物生长速率对非生物文石中锂和钠掺入的控制

在生物文石中使用 Li/Ca、Na/Ca 和 Li/Mg 比率在重建温度和/或盐度等环境参数方面表现出很高的潜力。然而，迄今为止，人们对控制文石中锂和钠等单价金属掺入的机制知之甚少。在这项研究中，实验研究了温度和生长速率对非生物沉淀文石中锂和钠掺入的影响。文石在 5、15 和 25 °C 下过度生长以及表面归一化生长速率范围 10 ≤ ≤ 10 (mol/m/s) 的结果表明，Li 和 Na 的表观分配系数（即 ）主要受矿物控制生长速度，而温度的影响较小。生长速率和温度对 和 的综合影响可描述为：
