Description
Summary:The compositional record of the AND-2A drillcore is examined using petrological, sedimentological, volcanological and geochemical analysis of clasts, sediments and pore waters. Preliminary investigations of basement clasts (granitoids and metasediments) indicate both local and distal sources corresponding to variable ice-volume and ice-flow directions. Low abundance of sedimentary clasts (e.g., arkose, litharenite) suggests reduced contributions from sedimentary covers while intraclasts (e.g., diamictite, conglomerate) attest to intrabasinal reworking. Volcanic material includes pyroclasts (e.g., pumice, scoria), sediments and lava. Primary and reworked tephra layers occur within the Early Miocene interval (1093 to 640 metres below sea floor mbsf). The compositions of volcanic clasts reveal a diversity of alkaline types derived from the McMurdo Volcanic Group. Finer-grained sediments (e.g., sandstone, siltstone) show increases in biogenic silica and volcanic glass from 230 to 780 mbsf and higher proportions ... : Supplement to: Panter, Kurt S; Talarico, Franco M; Bassett, K; Del Carlo, Paola; Field, B; Frank, T; Hoffmann, Stefan; Kuhn, Gerhard; Reichelt, Lucia; Sandroni, Sonja; Taviani, Marco; Bracciali, Laura; Cornamusini, G; von Eynatten, Hilmar; Rocchi, Sergio; SMS Science Team (2009): Petrologic and geochemical composition of the AND-2A Core, ANDRILL Southern McMurdo Sound Project, Antarctica.
