(from wikipedia) Clay is composed primarily of fine-grained phyllosilicate minerals typically formed over long periods of time by the gradual chemical weathering of rocks (usually silicate-bearing) by low concentrations of carbonic acid and other diluted solvents.Some clay minerals are formed by hydrothermal activity. Clay deposits may be formed in place as …
