John L Smellie
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, although alternating with subordinate thicknesses of strata derived from a predominantly granitoid source (Granite Harbour Intrusive Complex; GHIC). Above the 307 mbsf unconformities, the reverse situation occurs, with most sediments dominantly...
