Retention of the pristine hydrogen isotope composition (expressed as δD) formed during mineral formation in equilibrium with water is the basis for any paleoenvironmental reconstructions and for tracing mineral reactions using hydrogen (or H and O) isotope composition in kaolinite. Not only do post-formation reactions cause partial equilibration with ambient water, altering the pristine signature, but also result in the decoupling of H and O diffusion.

高岭石中氢同位素交换的动力学和 δD 特征保留随地质时间的变化预测


在矿物形成过程中形成的原始氢同位素组成（以 δD 表示）与水保持平衡，这是任何古环境重建和使用高岭石中的氢（或 H 和 O）同位素组成追踪矿物反应的基础。形成后反应不仅会导致与周围水的部分平衡，从而改变原始特征，而且还会导致 H 和 O 扩散解耦。
