Computer models in current use for describing water-rock interaction commonly involve the introduction of initially small amounts of rock into large volumes of water. Although this class of models has been very useful for the study of many types of geologic environments, this proposal suggests a new approach, where small amounts of water are put into a volume of rock. The conceptual difference between these approaches translates into a practical one where it is desirable to do calculations at low water-rock ratios, such as might be encountered in rock- buffered geologic environments including fracture development and vein formation or metamorphism.

目前用于描述水岩相互作用的计算机模型通常涉及将最初少量的岩石引入大量的水中。尽管这类模型对于研究许多类型的地质环境非常有用，但这项提议提出了一种新的方法，即将少量的水放入体积的岩石中。这些方法之间的概念差异转化为实际的差异，在低水岩比的情况下进行计算是可取的，例如在岩石缓冲的地质环境中可能遇到的裂缝发育和脉状形成或变质作用。
