The reflectance curves (0.2-2.5 μm) of montmorillonite,halloysite,illite and vermiculite were measured before and after heating of the samples.The reflectance spectroscopic characters of the clay minerals mentioned above and their relation to the chemical composition of the clay minerals were studiel.The methods for identification of the main types and di- and trioctahedra of clay mineral and for distinguishing dominant clay minerals in soils according to the reflectance utrves of the soils are proposed.It is also suggested that the reflectance curves of soil profile can be used fir interpretation of the soil properties and its genetic characteristics.
