Dynamic provenance variations are deduced from sand-grain detrital modes in samples obtained from the CRP-2/2A drillcore. Below an important unconformity at 307 metres below sea floor (mbsf), sand grains in most of the sequence were dominantly derived from Beacon sandstone and Ferra dolerite sources...
