Geochemical investigations of elements in sediment core CRP-1 from the Ross Sea, Antarctica, supplement to: Bellanca, Adriana; Neri, Rodolfo; Palumbo, B (1998): Provenance of CRP-1 drillhole fine-grained sediments, McMurdo Sound, Antarctica: evidence from geochemical signals. Terra Antartica, 5(3), 639-643

Geochemical data are presented for samples from strata, mainly of Miocene age, in the Cape Roberts-1 core (western McMurdo Sound, Antarctica) to assess the sediment provenance. Bulk (major and trace element) chemistry together with bulk mineralogy of fine-grained sandstones, siltstones, mudstones, and diamictites indicate that chemical alteration of source materials, fractionation due to sedimentary sorting, and diagenetic effects were not significant in the Cape Roberts sediment history. Relevant geochemical parameters are consistent with the Cape Roberts sediments being derived mainly from the crystalline basement and the Beacon Supergroup. On the basis of element distributions, an additional contribution from the Ferrar Dolerite and, mainly above about 60 m, influxes of detritus derived from basanitic to intermediate members of the McMurdo Volcanic Group are recognised.
