The aim of this paper is to present a brief description of the field relations of the South-West Granite Complex in the Island of Jersey, as shown by recent field work, together with a short description of the granites themselves. The area to be described forms a dissected peneplain, probably of Pliocene age. The magnificent coastal sections from St. Aubin to La Carrière reveal the nature of the two granite intrusions, the first into Pre-Cambrian shales, which are found to the north and north-east of the area; and the second a newer granite intrusion into the older one. Inland, the scenery is less spectacular, but the path from St. Aubin to Corbiére, which follows the old railway track, contains many excellent exposures of granite and shales, together with granite-shale contacts in the valley west of St. Aubin. West of Pont Marquet it traverses open country with dune sand encroaching from St. Ouen's Bay.
