The ice impurities are fractions of the atmospheric aerosol that have been deposited on the surface of the ice sheets via wet or dry deposition. In the study of ice core stratigraphy, insoluble microparticles are one of the components of ice impurities analyzed. Changes in impurity content of the ice core strata reflect change in atmospheric conditions of past climate. During the second half of the 20th century, scientists paid more attention to microparticle study in the polar ice, however many scientists started concern on the microparticel study on the Qinghai-Xizang plateau in the last ten years of the 20th century. As of now, there have been four ice cores and many snow samples that have been studied in microparticle on the Qinghai-Xizang plateau. The study is mainly focuses on calculating time by microparticle, microparticle concentration, size distribution, abrupt event record and relationship with soluble ions. This article reviews the methodologies and results of microparticle study on the Qinghai-Xizang plateau starting from last ten years of the 20th century, and some important tasks are also proposed, including (1) the studies of mineralogy and isotopic composition; (2) deposition process and post-deposition process; (3) the role in the microorganism research of ice-snow.
