Abstract: Field work was carried out on basement rocks in the St. Johns Range, McMurdo Dry Valleys. Rock samples of dyke swarms exposed in homogenous granite on the Kukri erosion surface were collected, granitoid bodies on the eastern ridges to the north and south of the Willis Glacier (Schist Peak) were mapped and the contact relationships and internal characterisitcs of plutons were studied and extensively sampled, the pluton boundaries on the ridges to the south and north of the Wheeler Valley were identified and mapped with detailed studies of the contact relationships and internal characteristics studied and related to those at Schist Peak and samples of several granites and an orthogneiss were collected for geochronological use.
