Abstract

In the Hong Kong area two high sea-level stages at 15 and 5–6 m P.D.1 are clearly marked. These appear to be the result of eustatic movements. A similar well-marked bench at —11 m P.D. represents a Late Pleistocene low sea level. At least one other period of low sea level, in which base levels were more than 60 m below P.D., occurred. Benches at 22 m, 40 m, and 71 m are found as remnants around most of the coast and are probably marine. Summit leveling at 130 and 230 m is common and may be marine or subaerial. A valley basement now abandoned at 430 m represents an old drainage line lightly incised into a subaerial surface indicated by summit heights of about 460m.
