This was the second season of a cooperative effort by GGU and the University of Liverpool which is aimed at determining the displacements and history of the boundary region. In addition to the writer, the following geologists participated in the mapping work: J. Grocott and D. Nash (University of Liverpool), C. Talbot (University of Dundee), and J. Diggens (Kingston Polytechnic). In addition G. Beckman and C. Morgan (Imperial College, London) carried out a palaeomagnetic sampling programme, and B. Scott (University of Edinburgh) a sampling programme on the kimberlitic dyke suite. Transport in the field was provided by the motor-boat 'Kimberlit' and two Zodiac infiatables, with some helicopter transport provided by Diapros Canada Ltd. which is gratefully acknowledged.
