Kaolinite Cerámica Wiki Fandom

Kaolinite clay occurs in abundance in soils that have formed from the chemical weathering of rocks in hot, moist climates - for example in tropical rainforest areas. Comparing soils along a gradient towards progressively cooler or drier climates, the proportion of kaolonite decreases, while the proportion of other clay minerals such as illite (in cooler climates) or smectite (in drier climates) increases.

Kaolinite is a layered 1 : 1 clay mineral, the layer being made of two different sheets, a tetrahedral silica sheet and an octahedral alumina sheet. Large dipole-dipole interactions, in addition to a network of H-bonds, link the siloxane surface of a layer to the aluminol surface of another layer, making intercalation of guest species in kaolinite challenging. There is however a limited number of molecular units

Fossil hunting? Look for the clay halo YaleNews

12.06.2020  The researchers discovered that such traces of early life were encased in halos of the clay known as kaolinite. The presence of kaolinite suppressed the decay of the cells of these organisms — which include bacteria, fungi, and algae — enabling their fossilization. A similar association promoted the preservation of soft-bodied Cambrian animals such as those in the Burgess Shale of British Columbia.

Kaolinite occurs in a range of climates but dominates in deeply weathered soils, in soils of higher landscapes and in regions with more rain. Illite is present in varied landscapes and may be representative of colder, more arid climates, but may also be present in warmer and wetter soil environments. Smectite is often an authigenic mineral, formed from the weathering of basalt, but it also occurs on sediments
