The authigenic clay minerals are composed of the following: illite-smectite mixed layer, illite, kaolinite, and chlorite (not detected in the samples). The dominant clay minerals are illite/smectite mixed layer, illite, and kaolinite respectively. The I/S mixed layer occurs as irregular flakes ...
Clay is a fine-grained natural material (soil or rock) comprising one or more minerals with small amounts of organic materials and metal oxides. Geologic clay deposits are mostly composed of phyllosilicate minerals, depending on the composition of the original materials. Clay can have different col...
structures of clay minerals In clay minerals the tetrahedral sheet is always combined with an octahedral sheet A cation (Al+3, Mg+2, Fe+2 etc. but not Ca+2, Na+1, K+1) is surrounded by 6 neighbors (oxygens or hydroxyls) Minerals composed of octahedral sheets. Brucit Mg3(OH)6 ...
This chapter discusses the applications of clays and clay materials as drugs. Clay minerals are efficient against several aggressors that cause major disorders of the gut. These beneficial effects of clay minerals (on the gastrointestinal mucosa) are associated with two mechanisms of action: (1) ...
The meaning of CLAY is an earthy material that is plastic when moist but hard when fired, that is composed mainly of fine particles of hydrous aluminum silicates and other minerals, and that is used for brick, tile, and pottery; specifically : soil compo
The abundance of smectite limits the application of some Koutaba and Marom clays for structural ceramics, while the high Fe2O3 contents (>8%) in some Bangourain clays indicate that some pre-treatment might be necessary prior to use.Clay MineralsMEFIRE, A. NKALIHFOUATEU, R....

Clay minerals such as kaolinite, smectite, chlorite, micas are main components of raw materials of clay and formed in presence of water. A large number of clays used to form the different structure which completely depends on their mining source. They ar

Clay mineralsAlbianParis BasinVocontian BasinPalaeoclimateHigh-resolution clay mineral analyses were performed on lower and middle Albian deposits from the Paris and Vocontian basins in order to specify the weathering conditions that prevailed at that time. The clay mineral assemblages are composed of ...
