Abstract

Dr F. Moseley thought that Dr Brown should be congratulated on completing this phase of research and writing up the results so quickly. The traverse, although limited by time and terrain, had proved to be a most meaningful one.

Another set of rocks, not specifically referred to by Dr Brown, had been collected from a suite of dykes which penetrated basalts on the other side of the glacier and Dr Moseley wondered whether they could have any relationship to the Lilloise Complex. Dr Moseley said he had begun to examine these rocks, but had not been so purposeful as Dr Brown, and had so far only made a general examination of thin sections. Nevertheless there was considerable variety which seemed to some extent to match that displayed by the plutonic complex. There were pure olivine rocks, serpentinized olivine, olivine clinopyroxene rocks, clinopyroxene brown amphibole calcic plagioclase rocks, and every gradation between. There was also more straight forward dolerite and, perhaps significant, an apparent absence of syenite. Would Dr Brown care to comment ?

Dr Moseley also said he would like to comment on the financing of expeditions such as Lilloise Expedition and others of similar style. It can be appreciated that funds are scarce and have to be shared between competing claims, but it seemed to be a false economy to provide just enough to get an expedition to the rock and then back home. A little extra would have made it possible to add several weeks to the field
