Abstract: Mineral particle is an important component of atmospheric particulate matters. The characteristics of mineral phase composition and micromorphology have important significance for researching on the mechanism of harm to human bodies, and have valuable information such as source and compositional variation of the particulate matter. From 1980s to present, the development of study on the composition and micro-morphology of mineral particles in China's atmospheric particulate matter can be generally classified into three periods (before 2000, 2000-2010, 2010-2017), based on the continuous exploration and improvement of research methods and techniques, and variation of research objects. Generally, research objects are changed from total suspended particles, to PM2.5 particles, even to less than PM2.5 particles in terms of particle size, and from bulk particles to individual particles in terms of analyzing objects. In addition, researches on mechanisms of the transformation of primary minerals and the formation of secondary minerals have been continuously paid attention to. Especially, we have proposed that the study on the partly sulfurized primary minerals and secondary sulfate particles is one of the most important research directions in future.
