The palygorskite (attapulgite) deposit in Georgia and Florida, United States, is over 60 km in length and may be one of the largest hormitic clay deposits in the world (Anon., 1978; Clarke, 1985). This deposit, which consists of 20-80% palygorskite (attapulgite) is thought to have resulted from marine sedimentation during the Miocene period (Harben

The smectic clays from Cabo de Gata region, Almeria, Spain, are composed mainly of montmorillonite, but they contain appreciable quantities of fibrous clay minerals, some of which are of the palygorskite type. However, there also is a mineral that has properties intermediate between those of palygorskite and sepiolite.

As nouns the difference between sepiolite and attapulgite is that sepiolite is (mineralogy) a hydrated magnesium silicate, claylike mineral used for carving into decorative articles and smoking pipes while attapulgite is (mineral) a clay mineral that is …
In attapulgite the strip width is of four tetrahedra and in sepiolite it is of six tetrahedra. The MgO 6 octahedra are arranged to give threefold strips leaving channels parallel to the fibre axis containing water molecules (Barrer, 1978). The idealised attapulgite composition for a half unit cell is Mg 5 Si 8 O 20 (OH) 2 (H 2 O) 4, 4H 2 O.
The outstanding absorption capacity of the special clays of the Sepiolite-Attapulgite group, allow us to elaborate a complete range of carriers with granular shape with low levels of dust generation.

Hydrothermal studies have failed to yield synthetic attapulgite or sepiolites in the system MgO-Al2O3-SiO2-H2O. However, the natural minerals can be decomposed to yield mont-morillonoids by mild hydrothermal treatment as low as 200°C and probably as low as 100°C. These data indicate that they are metastable and probably could not have formed at these temperatures.
Palygorskite or attapulgite is a magnesium aluminium phyllosilicate with the chemical formula (Mg,Al) 2 Si 4 O 10 (OH)·4(H 2 O) that occurs in a type of clay soil common to the Southeastern United States.It is one of the types of fuller's earth.Some smaller deposits of this mineral can be found in Mexico, where its use is tied to the manufacture of Maya blue in pre-Columbian times.
