Kaolinite: The clay mineral kaolinite information and pictures

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

Introduction to Clay Minerals & Soils

Clay minerals are layer silicates that are formed usually as products of chemical weathering of other silicate minerals at the earth's surface. They are found most often in shales, the most common type of sedimentary rock. In cool, dry, or temperate climates, clay minerals are fairly stable and are an important component of soil.

Soils can be acid, alkaline or neutral. Soil pH influences nutrient absorption and plant growth. Some plants, like kūmara and potatoes, grow best in a more acidic soil (pH of 5.0–6.0). Carrots and lettuces prefer soils with a neutral pH of 7.0. Soils can become more acidic over time as minerals are leached away.
