Chlorite is a common rock-forming mineral that is found in a variety of geologic environments including diagenetic, low- to high-grade metamorphic, and hydrothermally altered rocks with different bulk rock compositions. It displays a wide range of non-stoichiometric compositional variations depending on bulk rock composition and physicochemical conditions prevailed at the formation. The variation of chemical composition in chlorite, therefore, is useful to take off the information on the physicochemical conditions of the formation ; the use of chlorite composition for estimating the formation temperature is called chemical chlorite geothermometry. We developed a convenient geothermometer applicable to low-temperature chlorites and also verified the validity by applying it to several fields in the present study.

绿泥石是一种常见的造岩矿物，存在于各种地质环境中，包括成岩、低级至高级变质和具有不同整体岩石成分的热液蚀变岩石。它显示了广泛的非化学计量组成的变化，这取决于散装岩石成分和物理化学条件普遍在形成。因此，地层中化学成分的变化对于获取地层物理化学条件的信息是有用的;使用地层成分来估计地层温度被称为化学地层地质测温法。研制了一种适用于低温亚氯酸盐的简便型地温计，并将其应用于多个领域，验证了其有效性。
