A view towards the north east of a complex relationship between gneiss, amphibolite and granite. The relationship between the gneiss and amphibolite is essentially that shown in MS-03. The light-coloured granite sheet clearly post-dates both these units since it cuts them and contains xenoliths of them. Note that the country rocks on the north-eastern margin of the granite sheet have been deformed, indicative perhaps of displacement along the line of the granite sheet. This is also indicated by the apparent dextral offset of the thick amphibolite unit.
