| Geologically the axes from the New Guinea Highlands comprise thermally metamorphosed basalt, chert and greywacke depending on quarry source. |
| Higher vapour pressures would be generated in sediments of low permeability, such as mudstones, which would account for sills being more commonly found in shale and greywacke. |
| The group includes melange which consists of greywacke, limestone, pillow lava, gabbro and serpentenite blocks in a black shale matrix. |
