Dundurrabin Granodiorite under the microscope

3D Model

The Dundurrabin Granodiorite is a late Carboniferous member of the Hillgrove Plutonic Suite in the southern New England Orogen in eastern Australia. It is classified as an S-type granite and has a fairly simple mineral assemblage of quartz-plagioclase-biotite-microcline. The pluton was mildy deformed during the late Permian Hunter-Bowen Orogeny, giving rise to a weak foliation visible in hand specimen, and development of opalscent blue quartz and microcline replacing the original orthoclase.

This model has been generated from 161 images taken with an Olympus SC180 microscope camera attached to an SZ61TR stereo microscope. Images were taken by rastering across the surface. Each image is 18 MP and represents ~18×13 mm of the sample surface. Size of this surface is ~95×95 millimetres (front and left-hand edge in initial viewpoint). The model can be used to generate a flattened orthophoto of ~800 MP.
