| contents | Bulk chemistry (major and trace elements) of sand-sized samples from the CRP-2/2A drillhole provides evidence for a multicomponent provenance with changes in the component proportions throughout the sedimentary succession. Geochemical data evaluated in terms of element association and distribution and by means of cluster analysis reveal a provenance dominated by the granitoid basement with a significant contribution of MVG debris above ~310 mbsf. Chemical fingerprints of both basic and evolved MVG materials are recognized at different depths. Below ~310 mbsf the influence of Beacon sandstones becomes more marked, but there is geochemical evidence for influxes of detritus derived from Jurassic Ferrar Dolerites and Kirkpatrick basalt lavas. |
