    Clay is that size fraction of the soil that consists of particles of less than 2 m equivalent spherical diameter. The minerals that usually predominate in the clay fraction are termed clay minerals or phyllosilicates see Clay minerals silicates.Clay minerals are hydrous silicates or aluminosilicates, generally secondary, and they commonly form in nature by the alteration or weathering of ...

    Clay mineral - Origin | Britannica

    Clay mineral - Clay mineral - Origin All the clay minerals, with the possible exception of halloysite, have been synthesized from mixtures of oxides or hydroxides and water at moderately low temperatures and pressures. Kaolinite tends to form in alumina-silica systems without alkalies or alkaline earths. Illite is formed when potassium is added to such systems.

    Diagenesis is one of the most important factors that affects reservoir rock property. Despite the fact that published data gives a vast amount of information on the geology, sedimentology, and lithostratigraphy of the Ecca Group in the Karoo Basin of South Africa, little is known about the diagenesis of the potentially feasible or economically viable sandstones and mudrocks of the Ecca Group.

    It is a white or gray clay mineral, which is the chief constituent of kaolin clay. The precise chemical nature of the kaolin will be defined by the nature of the original feldspar, that is, whether it was aluminum, sodium, calcium or potassium rich, as these are the ions that will have been dissolved in solution.

    Clay minerals may be codeposited with sand grains as sandsized argillaceous intra and extraclasts and as flocculated clays. These sandsized argillaceous clasts are deformed by mechanical compaction into clay pseudomatrix. Detrital clay minerals may be incorporated into sandy deposits by bioturbation and infiltration of muddy waters.

    Halloysite and kaolinite occur in gneissic weathering profiles developed under a temperate climate in the Leucogia area of NE Greece. X-ray diffraction analyses of samples from three profiles of partially weathered gneisses have revealed that kaolinite becomes more abundant than halloysite with increasing intensity of the decomposition processes.

    Mineralogical analysis confirmed that biogenic plagioclase NaCa feldspar and illite were formed after bioreduction. Our work shows that the interaction between alkaliphile and iron-bearing smectite could account for low-temperature feldspar and illite formation and these minerals may be used as biosignatures in sedimentary rocks.
