In Oxisol which type of Clay is found

Oxisols are a soil order in soil taxonomy, for their occurrence in the tropical rainforest. The main processes of soil formation of oxisols are weathering, humification and pedoturbation due to animals.
Oxisols are specified by a thick subsurface layer that contains kaolin-group clay minerals ie. Kaolinite and metal oxides in a finely textured matrix with very little or no easily weathered silicates.
