(d) Collection of Samples

Samples of volcanic erratics, tills, "soil layers" and basement rocks were collected mainly from the Wright Valley. The tills are as yet poorly defined and are not known to be marine. Their mineralogy and chemistry will be the major laboratory study.

A sequence of algae samples has been collected from 10 surveyed bench levels above the north shore of Lake Vanda. A case for C¹⁴ dating will be made.
