Notes on a geological sketch map of Coronation Hill area, Northern Territory

The area shown in the accompanying geological sketch map, No. NT63/9, was surveyed in 1953. The mapping was carried out by using a grid marked out with improvised survey pegs at intervals of 100' along magnetic bearings N-S and E-W. The average error in this grid was quite small. The datum for the grid was chosen to coincide with that of the base line of the Coronation Hill plane table survey. Contours are based on levels obtained by aneroid barometer.
