The Caledonian and related geology of Scandinavia

The conference was introduced by M. Brooks, welcoming delegates to Cardiff, and was followed by a short session on basement geology. T. Emmett (CCAT Cambridge) described a series of dolerite dykes in the Jotun Nappe of S. Norway the geochemistry of which suggested that there had been a late Precambrian, pre-Caledonian extension of the Balto-Scandian continental margin. I. Bryhni (Oslo) followed with a description of the supracrustal rocks of the gneiss region of south Norway and the equivocal relationship of these rocks to the high pressure eclogitized rocks of the basement.
