| 1. | As a follow-up to our investigations a tentative programme is suggested for VUWAE 16 for 1971-72. This is to examine the volcanics exposed above 2,000 ft altitude at Cape Crozier, when photographs will then be available from U.S. Geological Survey. A visit to the Upper Koettlitz Glacier region could also be incorporated into this expedition to search for kenyte outcrops presumed to exist on Mts. Morning and Discovery. The source of the kenyte in moraines in the Lower Taylor Valley and at Black Island is presumed to have come from the Koettlitz region, but now some confirmation is required of this assumption by the early geologists. Examination of rock types on the flanks of Mt. Discovery could also be encompassed on this expedition, enabling a petrologist to carry out the first detailed sampling of this area. Collection of these samples could prove a valuable contribution in the understanding of the geochemistry of the McMurdo Volcanics and may also reveal some extremely important outcrops of kenyte. It is this type of "specific problem" research which is required in the future to solve the more
