Clays and clay minerals occur under a fairly limited range of geologic conditions. The environments of formation include soil horizons, continental and marine sediments, geothermal fields, volcanic deposits, and weathering rock formations.

Where does clay come from?
Clay comes from the ground, usually in areas where streams or rivers once flowed. It is made from minerals, plant life, and animals—all the ingredients of soil. Over time, water pressure breaks up the remains of flora, fauna, and minerals, pulverising them into fine particles.

Rice grows well in clay-like subsoil as the water retention capacity of the clayey soil is very high. Rice crop needs standing water.
What is clay soil good for?
“Clay soils hold huge amounts of plant nutrients because they have elevated cation exchange capacities,” said Brewer. This means they are able to hold on to nutrients, fertilizer and pesticides. Another plus for clay soils is that they hang onto water really well.
What fruit grows well in clay soil?
Many stone fruit trees like apricots and plums will do well in clay soils because they have a shallow root system. An apricot tree will get quite large and should be planted about 25 feet from other trees. Plant them the same way you would any other tree.

Is London built on clay?
Most properties in the Greater London area are built on London Clay, which is one of the most shrinkable of soil types of all as it’s highly susceptible to changes in volume caused by high water content.
Is there red clay in England?

Is clay a mud?
Simply put, clay is mud. … Clay is not a single mineral, but a number of minerals. Clay has a high Alumina (AL) and Slicia content. Clays can also contain other materials such as iron oxide (rust) and rock fragments.
What type of mineral is clay?
Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them.
What exactly is clay?
Clay is a soft, loose, earthy material containing particles with a grain size of less than 4 micrometres (μm). It forms as a result of the weathering and erosion of rocks containing the mineral group feldspar (known as the ‘mother of clay’) over vast spans of time.
