Abstract: Attapulgite is of certain mineralogical features in chemical composition, X-ray diffaction and infrared spectrum. In Tarim basin, it is primarily distributed in Palaeogene, secondly in Cretaceous and Neogene. The formation is closely related to these geological factors such as arid-semi arid paleo-climate and water medium enriched with magnesian ions.

Key words: Tarim basin, clay mineral, attapulgite, mineral analysis, origin
