The perfect attapulgite crystal is the ctahedral extremes, while sepiolite is the magnesic and dioctahedral extreme [[9], [10]]. There is a continuous polysomatic series between the two extremes. Attapulgite should be a ctahedral mineral, in which the octahedral sites are all occupied by Mg 2+ ions.
