Figure 3. Examples of the thermomagnetic analyses of the Vendian rocks using the VFTB equipment (a and b) and of identifying magnetic minerals using the Lowrie method (c and d): (a) normal magnetization (Jr) curves and the curves of estimating the field of remanence coercivity (Hcr); (b) the curves depicting changes in the saturation magnetization (Js) in the course of heating and cooling (H denoting the saturation field value, Tc denoting the Curie temperature values); (c) isothermal magnetization curves; (d) the curves of the isothermal magnetization breakdown by temperature, the values of the magnetization field being 1 for the X, 2 for the Y, and 3 for the Z axis); Tub is denotes the value of the deblocking temperature.
