Milford Gneiss with ultramafic mega-boudins

Dioritic Milford Gneiss with ultramafic and mafic mega-boudins. See orange-brown garnet shape, indicating the ultramafic rocks,  above the lake.

This photograph was reproduced in black-and-white in an article by Peter Blattner in GSNZ Newsletter 126, p. 34.
The ultramafic pods did not show up well in monochrome, so the photograph is reproduced here in colour. It has not been enhanced.

For comments and discussion on the significance of these ultramafic pods, you can email p.blattner_at_gns.cri.nz
