Clay mineral in paleosols at Visonta, Hungary
Clay mineral associations of a paleosol sequence in the roof strata of the lignite mine at Visonta were studied by means of XRD, ТЕМ, FTIR, DTA. Investigations show that several clay mineral phases (smectite, kaolinite, illite, vermiculite) are present together in all the strata. High charge montmor...

| Summary: | Clay mineral associations of a paleosol sequence in the roof strata of the lignite mine at Visonta were studied by means of XRD, ТЕМ, FTIR, DTA. Investigations show that several clay mineral phases (smectite, kaolinite, illite, vermiculite) are present together in all the strata. High charge montmorillonite oocurs in the present day soil, high charge beidellite is characteristic of the red paleosol and montmorillonite and beidellite are present together in the grey clays. This various clay mineralogy indicate complex genesis of the strata. |
