Figures & data
Figure 1. Location of Colville Knolls and other selected bathymetric and geological features of the region. Background image is global multi-resolution topography (http://www.geomapapp.org; Ryan et al. Citation2009). Cross section of dredge sites based on multibeam data from Nathaniel B Palmer 9504 cruise. Geological features based on Isaac et al. (Citation1994) and Leonard et al. (Citation2010). Sample sites from Adams et al. (Citation2012, Citation2013). VDLL = van der Linden Lineament of Sutherland (Citation1999). CAVT = one of the cross-arc volcanic trails of Wright et al. (Citation1996).

Figure 2. Plane-polarised light image of thin section of dated sample R24690 (P78547). Image height c. 20 mm.
Figure 3. Detrital zircon age spectra. A, histogram, probability density function and significant component ages of Colville Knolls greywacke sample R24690. B, probability density function references of three North Island Cretaceous volcaniclastic greywacke sandstones R23783 and 23787 from Great Barrier Island (Adams et al. Citation2013) and R24204 from Whanarua Bay (Adams et al. Citation2012).
