    en.wikipedia.org/wiki/Palygorskite Palygorskite or attapulgite is a magnesium aluminium phyllosilicate with 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.

    www.britannica.com/science/palygorskite Palygorskite, a fibrous magnesium aluminum silicate. The structure of palygorskite contains extended silicon-oxygen sheets, justifying the retention of the mineral in the layer silicate family, but the tetrahedral SiO4 groups forming these sheets are oriented in such a manner as to develop

    www.sciencedirect.com/topics/earth-and-planetary-sciences/palygorskite Palygorskite is a clay mineral characterized by a microfibrous morphology, low surface charge, high magnesium content, and high specific surface area (Singer, 2002). Palygorskite-containing soils occur almost exclusively in arid and semi-arid areas of the world.

    www.sciencedirect.com/topics/.../palygorskite Palygorskite is a hydrous silicate containing Mg, Al and Fe 3+, whereas sepiolite is almost a pure hydrous magnesium silicate. Pore water solutions of alkaline pH with high concentrations of dissolved silica and magnesium favor the formation of both minerals. Fine fibrous textures and overgrowths of siliceous tests and opal-CT attest to their ...

    virtual-museum.soils.wisc.edu/display/palygorskite Palygorskite. Palygorskite (formerly called attapulgite) is a lath-like or fibrous clay mineral with a structure consisting of short and alternating inverted 2:1 sheets or ribbons. These ribbons have an average width (along the Y direction) of two linked tetrahedral chains in palygorskite (and three linked chains in sepiolite).

    www.galleries.com/Palygorskite Palygorskite, also known as attapulgite, is an odd mineral. It forms matted felted masses that closely resemble woven cloth. In fact, an informal name for this natural fabric is "Mountain Leather" and appears with attached calcite crystals that look like interwoven glass beads.. Palygorskite is often classified as a clay mineral because it is present in some soils and behaves like many other ...
