There is also a micro-granular variant of this type with porphyritic feldspars and hypersthene (bastite), and highly epidotized. An outcrop near the glacier (Fig. 5) consists of pyroxene-andesite of a type common among the older lava serie

There is also a micro-granular variant of this type with porphyritic feldspars and hypersthene (bastite), and highly epidotized. An outcrop near the glacier (Fig. 5) consists of pyroxene-andesite of a type common among the older lava series. It shows porphyritic feldspars (andesine), pale brown augite, and chlorite pseudomorphs after ortho- rhombic pyroxenes, in a very fine-grained intergranular ground-mass. The fourth specimen, from the shore, is an igneous breccia mainly composed of angular fragments of altered andesite, much epidotized, and peppered with cubes of secondary pyrites. Mr Ferguson's specimen of igneous breccia from the same locality, however, is rich in fragments of the more acid dacitic and rhyolitic lavas.
