Research Abstract

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.
