16. Structural Observations in the Robertson Bay Terrane and Their Implications

In the area measured, almost upright, steeply NE verging, open folds of some 100 m in amplitude characterize the style of the mainly single phase deformation. This confirms earlier observations in the adjacent areas of the Robertson Bay Terrane to the south and to the east. In accordance with the vergence, cleavage in average is dip­ ping steeply to the south-west (s: = 251/85, dip directions by CLAR compass.). Fold axes are plunging between 20" to the SE and20" to the NW (average 130/10).
