P(論文) The sediment core DVDP 14 of 28m in length was drilled at the center of the dry basin in North Fork located 1.5km from the western edge of Lake Vanda, which is marked by a great fluctuation in water level during the past lake history, as has been pointed out by the previous studies. Preparing 35 samples from the core at different depths and subjecting them to sieving (mechanical and micro), size frequency distributions were investigated and depositional environments were analyzed by their vertical profiles, whereby it was inferred that the lucustrine and the aeolian deposition alternated with each other, corresponding to the pluvial condition (warm climate; higher water level) and the dry condition (cold climate; lower water level) in the lake area. departmental bulletin paper
