摘要:

Polygonal ridge patterns with intervening hollows some 400 m across and with a relief of about 100 m are common as low hills on the northern dissected part of the Sepik piedmont. They are developed in Pliocene mudstone and sometimes in marl and greywacke. The crests of the highest flat‐topped hills have a veneer of Pleistocene fanglomerate on them.
