Abstract:
A new technique that coupled SHRIMP (Sensitive High Resolution Ion Microprobe) U-Pb analyses with Laser ablation ICP isotope analyses for detrital zircons enabled the provenance of sediments from the English Coast region to be better assessed than had been previously possible. Such analyses, combined with Sm-Nd, Sr and Pb analyses for the sediments and plutonic rocks that cut the sediments, enabled a better assessment of the affinity of the English Coast rocks.
