Sedimentological investigation on 4 cores from the Antarctic continental margin, supplement to: Hillenbrand, Claus-Dieter; Ehrmann, Werner (2003): Palaeoenvironmental Implications from Tertiary Sediments of Kainan Maru Seamount and Northern Gunnerus Ridge. Antarctic Science, 15, 522-536

Claus-Dieter Hillenbrand & Werner Ehrmann
Sedimentary sequences spanning early Oligocene and Neogene time intervals were recovered with piston and gravity cores along erosional structures at northern Gunnerus Ridge and Kainan Maru Seamount in the southernmost Indian Ocean. Results of sedimentological investigations help to reconstruct the Cenozoic palaeoenvironment. Main emphasis was placed on grain size and clay mineral data. The clay mineral assemblages are dominated by illite and smectite. Chlorite and kaolinite occur in trace amounts. Whereas illite has a distinct...
