WebThis oxygen atom is bonded to a hydrogen atom forming an OH group in the clay structure. Clays can be categorized depending on the way that tetrahedral and octahedral sheets are packaged into layers. If there is only one tetrahedral and one octahedral group in each layer the clay is known as a 1:1 clay. WebHow does kaolinite clay form? Plant Acids Some roots and decaying plants give off acids that also dissolve minerals in rock. When the minerals dissolve, the rock is weakened. Eventually, the rock breaks into smaller pieces. As the rock weathers, nutrients become available to plants. in custody brainerd mn
