Figure 6. The typical thermomagnetic spectra of the goethite-hematite ferromagnetic rock association (silty clay of Samples 1 and 2), of the magnetite-maghemite-hematite association (sandstone of Samples 4, 7, and 8) and of the maghemite-hematite association (silty clay of Samples 5 and 6). The broken line shows the spectra of the second heating. (a) shows the Tatarian rocks at the Putyatino outcrop, (b) shows the outcrops of the Triassic (Indian) rock outcropping in the Shilikha area.
