MECHANOCHEMICAL IMMOBILIZATION OF COPPER BY DIOCTAHEDRAL AND TRIOCTAHEDRAL SMECTITES
, 2012 Clay minerals have revealed highly potential in soil remediation due to their low cost, availability, and low toxicity. Mechanochemical processes allow to activate chemical reactions by inducing different kinds of mechanical stress and without any ...

Vermiculitization of phlogopite in Metagabbro, central Turkey
, 2001 Dioctahedral vermiculite occurs in an isolated metagabbro klippe (Kurancali Metagabbro) that belongs to the Central Anatolian Ophiolites from central Turkey. Both the metagabbro and the structurally underlying high-grade metamorphic rocks are intruded by

Rietveld refinement of chapmanite SbFe2Si2O8OH, a TO dioctahedral kaolinite-like mineral
, 1998 Chapmanite, Sb(OH)Fe2(SiO4)2 is a rare mineral that generally occurs as yellow coatings on rocks from antimony mines. The very small dimensions of the crystals prevented X-ray single-crystal study of the mineral whose structure was derived through high ...

Relationships between composition and structure in Fe-rich smectites
, 1983 Chemical and erystalloehcmical properties of natural dioctahedral Fr smectites formed by weathering of basaltic rocks in the Beriei-Euganei Area, northern Italy, were investigated. It was found that: (i) the b-dimension could be correlated both to Fe3+/E
