Clay mineralogy of sediment core CRP-1, supplement to: Ehrmann, Werner (1998): Lower Miocene and Quaternary clay mineral assemblages from CRP-1. Terra Antartica, 5(3), 613-619

Werner Ehrmann
Clay mineral assemblages in lower Miocene and Quaternary sediments recovered at the CRP-1 drillsite, McMurdo Sound shelf, Antarctica, were analysed in order to reconstruct source areas of the sediments and late Cenozoic Antarctic icedynamics. The assemblages are dominated by smectite, illite and chlorite. Kaolinite occurs in trace amounts only. The lower part of the drillcore, below c. 70 mbsf, is characterised by high illite and chlorite, but low smectite concentrations. This assemblage is typical of...
