Abstract

The Niigata sand dunes are classified into three groups. The Recent Dunes I, II and III, in accordance with the geohistory of the formation. As a result of excavation and research in the sand dune area, we reached the following conclusions.<br>1. Relics of the beginnings of the early Jomon period were found on the Recent Dunes I-1 and of the late Jomon period were found on the Recent Dunes II. From this it may be inferred that these sand dunes were formed earlier than previous reports indicated.<br>2. Judging from the fact that the buried sand dunes were found under the alluvial plain, it was confirmed that those sand dunes were correlated with the Recent Dunes II.<br>3. As the result of heavy mineral analysis of sand grains of the Recent Dunes I-4 and II, we can hypothesize about the relation between the supply of sand grains and volcanic activity.
