Abstract
CLAY MINERALS OF THE TURONIAN ROCKS IN THE VICINITIES OF ANNOPOL ON THE VISTULA RIVER
Summary
In the Turonian rocks occurring at the walls of the Vistula River valley, near Annopol, between Jakubowice and Opoczka, beside carbonates (calcite, dolomite) and free silica (quartz, chalcedony, opal), also clay minerals have been observed.
On complex methods such as colorimetric analysis, thermal-differential analysis, x-ray analysis and electron- microscope analysis, the polymineral character has been ascertained of the rocks examined. Among clay minerals, hydromica (illite) and montmorillonite play the main parte there. Kaolinite occurs as slight admixture, only.
Examinations of physical and mechanical properties of the Turonian rocks have shown that differences in behaviour of the rocks under water saturation, resulting in swelling, contraction, compression strength and softening, depend upon the content of clay minerals, mainly that of montmorillonite.
