The clay mineral assemblage in an area of active deposition is dependent largely on the character of the source area This conclusion is based on a study of the clay mineralogy of sediments of the lower Mississippi River, the active delta region, the St Bernard Sub ,...
Kaolinite is a clay mineral, with a soft consistency and earthy texture It is easily broken and can be molded or shaped, especially when wet Kaolinite is a lackluster and uninteresting mineral on its own, but it occasionally forms interesting pseudomorphs, especially after feldspars It is also a common accessory to other minerals, including gem crystals in decomposing feldspar pegmatit...
clay A dried mineral clay under the names of sikor, mithi, pakhuri, and khatta, is sometimes used in Asia as a treatment for indigestion and a nutritional supplement, but can be toxic since it contains varying amounts of arsenic and lead...
Abstract Clay is an inherently occurring material constituted with fined-grained mineral The minerals are generally less than 2 microns and occur to be plastic in water content which solidify when dried...
Water saturated with CO2 at about 25??C was percolated through mixed beds of limestone or marble fragments and montmorillonite, illite and kaolinite in polyethylene tubes for six and fortyfive complete runs The leachates were analysed for SiO2, A12O3 and Fe2O3, but only SiO2 was found The minerals lost SiO2 in this order montmorillonite >kaolinite > illite...
The high ammonium environment associated with hydrothermal activity is expected to enhance formation of ammonium-bearing clay minerals, and then the d 15 N value of MN fixed in the clay minerals is possibly preserved a signal of pore fluid ammonium...
The precipitation of cements in quartzarenites and subarkoses deposited in a marine environment tends to follow a predictable pattern beginning with clay authigenesis associated with quartz and feldspar overgrowths, followed by carbonate precipitation...
