Quaternary (geological) maps, on both small and large scale, published in various countries (see references) are reviewed compared with the recently published Quaternay Maps of Japan, which comprise I. Landforms, Geology and Tectonics (1:1, 000, 000, three sheets) and II. Prehistoric Remains and Paleogeography (1:4, 000, 000, one sheet with four maps). These maps were compiled by an editorial committee of the Japan Association for Quaternary Research, and published by the University of Tokyo Press in July 1987.
Several general problems concerning Quaternary maps are discussed: (1) arrangement of legends and of time-space diagrams, (2) presentation of overlapping and underlying layers and topographic surfaces, (3) expression of denudational slopes formed during the Quaternary, (4) expression of submarine features, and (5) paleogeographic maps.
