The late Mesozoic Marum and Papuan ophiolites of Papua New Guinea dip from the continental margin towards accreted Paleogene island-arcs and appear to represent frontal-arc basement emplaced as a result of a mid-Tertiary continent/arc collision.

This report is a summarised account of an investigation into the heavy mineral content of three bores, put down by the Roma Blocks Oil Company. The positions of the bores and a short account of the geology of the area are given, together with results of the work to date, and an evaluation of the prospects of correlation by petrological means.

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.
