英文摘要	On the basis of investigating the characteristics of the geological background, ore-forming stages and its geologic age, geochemistry and isotope of Targejia hot spring-type cesium deposit, this article systematically studies the characteristics of mineralogy and fabric of gyserite, which will show great significance for understanding ore-forming process of this deposit. The study indicates that the early stage contains a lot of Quartz, but the late stage only consists of opal. Grannular opal exists from early to late stages while colloform opal mainly occurs in the late stage. The cauliflower-liked, megagrained massive, pore and corrosion structures exist in early stage. Fine-grained massive and pore structure exist in late stage. In the 3nd stage, there is Denticula genus of diatom, which has the characteristics of low-temperature stage. From early to late stage, the content of SiO2 gradually falls while contents of (Na2O + Al2O3 + K2O +CaO) and Cs2O rise. The reason is that impurity components are not expelled from crystals with the falling degree of SiO2-ordering.
