Abstract: In this paper, the transverse distributive regularity and its controlling factors of clay minerals inTertiary System in Qaidam Basin was carried out. From the marginal facies to the centeral facies of theBasin, the ralative content of interstratified illite/smectite has a tedency of decrease and the ralative con-tent of illite increases obviously. In Neogene system, there are two types of combination of the clay min-erals. The one of them is the combination of randomly interstratified illite/smectite→illite→ chlorite→kaolinite in the marginal facies of the Basin. The other is the combination of ordered interstratified illite /smectite →illite → chlorite→ kaolinite in the central facies of the Basin. In Eogene System have two typesof combination. The one is the composition of ordered interstratified illite/smectite→ illite→ chlorite→kaolinite.The other is the combination without kaolinite. The distributive regularity of clay minerals in NeogeneSystem was controlled chiefly by arid-semiarid peleoclimate, composition of source rock and peleosedi-mentary environment. In Eogene System, because the sediments were buried very deep, it was controllednearly completely by digenesis, but the sedimentary environment still was a its important controlling fac-tor.
