Description:

During the International expedition of the research vessel Dmitry Mendeleyev three sectors of the Western Pacific Ocean were studied: Philippine Sea, Solomon Sea and Coral Sea. From these areas also the samples for the orientation were taken in order to do the mineralogical examination with them. Above all, X-ray diffraction technique was used beside the chemical analysis performed by electron microprobe analyzer. Quantitative evaluation of min eral components was carried out applying X-ray diffraction. Standardless technique based on the adiabatic principle enabled th e quantitative determination directly from the X-ray diffraction diagram. Generally, sheet silicates - above all smectite, chlorite, mica (illite) - play the leading role in the mineral composition of collected samples of muds taken from the ocean floor. Besi des, also minerals of terrigenous origin are present: quartz prevailing mostly over feldspars (plagioclase > K-feldspar). Amphiboles and pyroxenes occured, but not everywhere. Carbonate minerals (calcite >> aragonite) were found only in samples from Coral Sea., Karel Melka, Ferry Fediuk and Anna Langrová., and Obsahuje bibliografické odkazy
