Mapping and sampling of the Granite Harbour Intrusives from the Pipecleaner Glacier-Miers Valley area

Detailed mapping and sampling of the Granite Harbour Intrusives was carried out in the Pipecleaner Glacier area and in the Miers Valley forming an extensive petrological and structural study of various plutons forming part of the Granite Harbour Intrusives. The work was aimed at determining the actual size of the Bonney Pluton. Catacomb Hill, a north-south trending ridge approximately 4km long at the southern end of the Blue Glacier, was visited to compare the granitoids at this location those analysed previously from the Taylor Valley and Ferrar Glacier region to determine if they are completely separate suites. A representative number of samples of granitoids were mapped and collected for whole rock analysis by x-ray fluorescence analysis.
