由于对CO2地质封存背景下的地球化学CO2-流体-岩石相互作用的浓厚兴趣，越来越多的研究小组使用各种不同的实验方法来识别重要的地球化学溶解或沉淀反应，并在可能的情况下量化矿物或岩石蚀变的速率和程度。在这次实验室间对比中，11个实验室对三种造岩矿物样品的气-液-矿反应进行了研究。报告的结果指出，大多数团体在实验中的主要过程的鲁棒识别。从水相组成变化中得出的溶出速率总体上是一致的，但通过对反应池中随时间变化的参数进行类似的校正，可以减少变化。实验装置和程序以及数据校正的比较确定了未来气体流体岩石研究的潜在改进。
Due to the strong interest in geochemical CO2-fluid-rock interaction in the context of geological storage of CO2 a growing number of research groups have used a variety of different experimental ways to identify important geochemical dissolution or precipitation reactions and – if possible – quantify the rates and extent of mineral or rock alteration. In this inter-laboratory comparison the gas-fluid-mineral reactions of three samples of rock-forming minerals have been investigated by 11 experimental labs. The reported results point to robust identification of the major processes in the experiments by most groups. The dissolution rates derived from the changes in composition of the aqueous phase are consistent overall, but the variation could be reduced by using similar corrections for changing parameters in the reaction cells over time. The comparison of experimental setups and procedures as well as of data corrections identified potential improvements for future gas-fluid-rock studies.
