2019年1月1日 Sepiolite is a typical fibrous Mg-rich silicate clay mineral, with the fiber length up to several micrometers. It is an end-member of the palygorskite/sepiolite polysomatic series, with the formula of Mg 8 Si 12 O 30 (OH) 4 (OH 2) 4 •8H 2 O [1].The channels with the size of 1.06 nm × 0.37 nm cross the fibrous crystals, which are formed by the linkage of continuous

L'un d'entre eux a fourni lui aussi des minéraux fibreux (attapulgite). Les lignites, quant à eux, étudiés du point de vue pollinique par J. Medus (1964) peuvent être rapportés au Miocène (Tortonien, Pontien) (Medus et Nonn, 1963 et Medus, 1964). Il y a donc toutes chances pour que les sédiments à attapulgite soient eux aussi aquitaniens.
세피올라이트 63800-37-3 - ChemicalBook
Sepiolite is similar to attapulgite but has an additional SiO4 tetrahedron at regular intervals on the chain, so that the united cell is about 50% larger than that of attapulgite; usually clay-like, nodular, and fibrous; also compact massive (meerschaum) or leathery (mountain skin)..

them compares sepiolite slurry with the other well known mud slurries, namely bentonite and attapulgite, Serpen et al. (1992). In their experimental work, they compared sepiolite mud with bentonite and attapulgite muds at room condition and obtained that sepiolite mud gave superior rheological and filtration properties for various salinities.
