A thirteen day excursion to Britain during September 1975 provided the opportunity to visit briefly the major outcrops of late Precambrian rocks of England, Scotland and Wales. These included (l) a fossiliferous vulcano-sedimentary sequence at Charnwood Forest, (2) the Dalradian Supergroup of the Scottish Highland including very late Precambrian stromatolites and tillites, (3) the Moine succession that underlies the Dalradian, (4) the late Precambrian Stoer and Torridon Groups of redbed clastics that unconformably overlie Lewisian basement meta-morphics west of the Moine Thrust, (5) the latest Precambrian eugeosynclinal Monian Supergroup of Anglesey, including a melange containing stromatolitic limestone and (6) the ?latest Precambrian or Cambrian Longmyndian succession of shallow water clastics and volcaniclstics. Research in Precambrian and early Palaeozoic acritarchs in the Torridon and Stoer Groups and the Dalradian Supergroup indicates the potential for similar studies to be carried out in the Adelaide Geosyncline.
