1. Crystal Chemistry of the Erebus Lava Flows

Samples of Kenyte containing anorthclase and plagioclase feldspar crystals were collected from exposed lava flows at Cape Royds, Barne, Evans, Turks Head and the Dellbridge Islands. Structural studies by X-ray diffraction methods will be carried out on these feldspars to see if the Si/Al distribution in them can be determined, and if the crystallographic parameters can be used to correlate the flows.
