The clay fraction of a Balmoral, Griffin and Clovelly soil was studied by selective dissolution analysis, cation exchange measurements, and thermogravimetric analysis. Amorphous material varying from 20% to 40% were present in all three soils. In general, the chlorite content varied between 20% and 35% while the kaolin content varied between 40% (Balmoral) and 15% (Clovelly). 10% to 20% mica was found in the Clovelly and Griffin soils, probably present as small isolated residual cores… CONTINUE READING
