Detrital modes for the sand-size fraction in 24 samples from the CRP-1 drillcore are described. Most samples are largely composed of quartzo-feldspathic detritus sourced dominantly from Palaeozoic granitoids and quartzose sedimentary sequences. Minor contributions from basic lamprophyre dykes, felsi...
