摘要: 坡缕石在化学成分、X射线衍射、红外光谱等方面都具有一定的矿物学特征。塔里木盆地坡缕石主要分布在下第三系,其次为白垩系和上第三系。坡缕石的成因与干旱-半干旱古气候和富含镁离子的水介质等地质条件有密切关系。

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
