| Purpose | Research |
| Objectives | The principal scientific aims of the programme were:
1. to investigate the continuation of the Great Glen Fault and associated faulting in the area from Lismore Island to south west of Colonsay - locating its position, finding whether it bifurcates, and elucidating its history of post-palaeozoic movements by determining the development of Mesozoic and younger strata on both sides of it; 2. making detailed investigations of the submerged Tertiary igneous centre near Stanton Banks which has been recognised from the I.G.S. aeromagnetic maps by the Geophysics Section of I.G.S. some years earlier. |
